Highlights from Maximinus’s Debate With Augustine

The debate between Augustine of Hippo and Maximinus the Homoian is well worth reading for anyone interested in understanding the theology of either Augustine or the Homoians. Maximinus’s lengthly explanations of his views provide one of the best primary sources we have on the details of fifth-century Homoian trinitarianism. It is noteworthy for its close resemblance to the theology of prominent second and third-century church fathers such as Justin Martyr and Novatian of Rome. Below are a few brief selections from Maximinus’s portion of the debate.

These excerpts show, among other things, that Maximinus and the Homoians at large, as represented by the ecumenical council of Arminium, were not Arians, as they are so often slandered as being. The thematic stress on the Father’s supremacy and infinitude, although something Arians agreed with, can be seen in the ante-nicene fathers going back to Novatian, Irenaeus, and Justin Martyr; it is by no means a mark of Arianism.

Maximinus said:

“In the case of God you should use a worthy comparison. I am, of course, displeased and pained at heart over what you go on to say, namely, that a human being generates a human being, a dog a dog. You should not use so foul a comparison for such greatness.†106

15, 7. “Who does not know that God begot God, that the Lord begot the Lord, that the King begot the King, that the Creator begot the Creator, that the Good begot the Good, that the Wise begot the Wise, that the Merciful begot the Merciful, and that the Powerful begot the Powerful? In generating the Son, the Father took nothing away from the Son. He is not envious, but as the source of goodness he begot this great good.†107 All of creation bears witness to his goodness, in accord with your statement, which I highly praise.†108 You drew from the divine scriptures the words, From the creation of the world his invisible reality, having been understood, is seen through those things that have been made, even his everlasting power and divinity (Rom 1:20).”

“Moreover, it is proper and a mark of order that you employ worthy comparisons. After all, you are speaking of God, of that immensity, to which, even if one draws a comparison as great as possible in terms of human thought or even in accord with the authority of the divine scriptures, one finds that the comparison is inadequate in every respect to him who is incomparable.

15, 10. “In accord with the testimonies that I have produced, I say that the Father alone is the one God, not one along with a second and a third, but that he alone is the one God. If he alone is not the one God, he is a part.†122 I deny, after all, that the one God is composed of parts; rather, his nature is unbegotten, simple power. The Son before all ages is himself begotten as power. The apostle spoke of this power of the Son, When you and my spirit are gathered together with the power of the Lord Jesus (1 Cor 5:4). I state and profess what the holy gospels teach us. I state and profess that the Holy Spirit is also power in his proper character. The Lord bore witness concerning him, when he said to his disciples, Remain in the city of Jerusalem, until you are clothed from on high with power (Lk 24:49).

15, 12. “The apostle says, The blessed and alone powerful, the King of kings. He calls the Father alone powerful, not because the Son is not powerful. Listen to the Holy Spirit crying out and bearing testimony to the Son, Lift up the gates, you†125 princes; be raised up, eternal gates, and the king of glory will enter. He continues, Who is this king of glory? Listen to the answer, The Lord strong and powerful (Ps 23:7-8). How can he fail to be powerful, when every creature proclaims his power?

15, 13. “How can he fail to be wise, when the Holy Spirit cries out in praise of his wisdom and says, How magnificent are your works, O Lord! You have made all things in wisdom (Ps 103:24). Since all things were made through Christ, the Holy Spirit undoubtedly praises him when he says, You have made all things in wisdom. Since that is so, we must ask how blessed Paul can say, The blessed and alone powerful. In my opinion, he calls him alone powerful, because he is alone incomparable in power. In awe before his incomparability, the prophet said, O God, who is like you? (Ps 82:2). Do you want to know that he alone is powerful? Look at the Son and admire the power of the Son. Recognize in the Son that the Father is alone powerful, because he has begotten one so powerful. In his immense power the Father begot the powerful creator.†126 In his power that he received from the Father, the Son did not create the creator, but established creation. He says, All things have been handed over to me by my Father (Mt 11:27). In awe of this power of God the Father, Paul said, The blessed and alone powerful. Job was a powerful and true man. We read, That man was a true and just worshipper of God, and in further describing his region, it says that he was powerful and great among all those in the East (Jb 1:1.3). How then can the Father alone be powerful? It says alone, because no one is comparable to him, because he alone has such greatness, such might, such power.

“In the same way, the blessed apostle Paul proclaims that the Father alone is wise, when he says, God who alone is wise (Rom 16:27). But we must look for an explanation of why he alone is wise, since Christ is also wise. You have already cited Christ the power of God and wisdom of God (1 Cor 1:24). We too have given testimonies that he created all things in wisdom. But the Father alone is truly wise. We believe the scriptures, and we venerate the divine scriptures. We do not want a single particle of a letter to perish, for we fear the threat that is stated in these divine scriptures, Woe to those who take away or add! (Dt 4:2). Do you want to know how great is the wisdom of the Father? Look at the Son, and you will see the wisdom of the Father. For this reason Christ himself said, One who has seen me has also seen the Father (Jn 14:9). That is, in me he sees his wisdom; he praises his might; he glorifies the Father who, one and alone, has begotten me, one and alone, so great and so good before all ages. He did not look for material out of which to make him, nor did he take someone as an assistant. Rather, in the way he knew, he begot the Son by his power and his wisdom.†127 We do not profess, as you say when you falsely accuse us, that, just as the rest of creation was made from nothing, so the Son was made from nothing like a creature. Listen to the authority of statement of the Synod; for our fathers in Ariminum said this among other things, ‘If anyone says that the Son is from nothing and not from God the Father, let him be anathema.’†128 If you want, I will offer testimonies. For the blessed apostle John speaks as follows, One who loves the Father also loves him who was born from him (1 Jn 5:1).

“This is painful to hear, for you do not compare that great magnificence to the nobility of the soul, but to the fragility of the body. Flesh is, of course, born from the body, a bodily offspring. But the soul is not born from a soul. If, then, our soul generates without corruption and passion, not experiencing any lessening or any defilement, but lawfully in accordance with God-given rights generates an offspring, in wisdom giving its consent to the body,†130 it itself remains whole. How much more will the omnipotent God do so?†131 I said just before that words fail us in every human comparison with God,†132 though we try to put it as best we can. How much more incorruptibly has the incorruptible God the Father begotten the Son? He has, however, begotten him. Note my carefulness, for I have the testimonies of the holy scriptures, Who will tell of his generation? (Is 53:8). He begot as he willed, as one with power,†133 taking nothing away; he begot one with power without any envy entering in.

“You say that God is one. Show me whether the Father and the Son and the Holy Spirit are one God or whether we should call the Father alone God, whose Son, Christ, is our God. Are you urging us to profess one God the way the Jews do? From the subjection of the Son, are we not shown, as the Christian faith holds, that there is one God whose Son is our God, as we have said? Believe Paul that the Father and the Son are not a single one (unus), as he proclaims in nearly every letter. He says, Grace and peace to you from God our Father and the Lord Jesus Christ (Rom 1:7; 1 Cor 1:3; 2 Cor 1:2; Gal 1:3 and Eph 1:2). He also says, One is God the Father, from whom are all things, and we are in him,
and one is the Lord Jesus Christ, through whom are all things, and we are in him†166 (1 Cor 8:6). This is the one whom we Christians preach as the one God, and the Son proclaims that he is good, when he says, No one is good save the one God (Mk 10:18). It is not that Christ is not good, for he says, I am the good shepherd (Jn 10:11). It is not that the Holy Spirit is not good; hear the prophet as he cries out, Your good Spirit will lead me in the right path (Ps 142:10). Hear too the witness of the Savior who says, A good man brings forth good things from the treasure of his heart (Lk 6:45). Moreover, every creature of God is very good. If a creature is good, if man is good, if the Holy Spirit is good, if Christ is good, we must investigate how there is one who is good. The Savior, of course, said, No one is good save the one God, because he is the source of goodness and has received his goodness from no one. Christ has received his goodness from his Father so that he is good, and every good creature of God has received through Christ its goodness. But whether it is the Son or those who were made through him, each has drawn his goodness from that one source of goodness in accord with the measure of his faith. But the Father has received his goodness from no one. Thus Christ says, No one is good save the one. In that way, then, there is one God, because there is one who is incomparable, because there is one who is immense, as we have already stated.†167
15, 24. “We do not deny that the Son loves the Father, for we read the scripture, So that this world may know that I love the Father, and I do just as he has commanded me (Jn 14:31). It is clear that the Son is loved and loves and that he carries out the commandment of the Father, as he says. Thus they are one, in accord with his words, The Father and I are one (Jn 10:30). Insofar as he says, He who has seen me has also seen the Father (Jn 14:9), we must believe with certain faith that he who sees the Son sees and understands the Father through the Son.

15, 25. “You professed that the Father is greater on account of the form of the servant.†168 That strikes me as quite foolish. We know that you also said that he was made less than the angels in the form of the servant.†169 You have not sufficiently proclaimed†170 the glory of God in professing that the Father is greater than the form of the servant. Even the angels are greater than the form of the servant. Christ did not come to teach us that the Father is greater than the form of the servant. Rather, the Truth came to us to teach and instruct us that the Father is greater than the Son and greater than this Son who is the great God. We glorify the Father and profess that he is greater than the great God; we proclaim that he is higher than the high God. Is this the honor we owe to God that the Father is greater than the servant form?

15, 26. “You say that the divinity showed itself to the Patriarchs, and just before that you said that the divinity was invisible.†171 The Father, who is invisible, surely did not show himself. Otherwise, if we say that the Father was seen, we make a liar of the apostle, who says, No human being has seen him or can see him (1 Tm 6:16). Moreover, we find ourselves not only in opposition to the New Testament, but we are equally in opposition to the Old Testament as well. After all, Moses speaks this way too, No one can see God and live (Ex 33:20).

“This same Moses wrote in the Book of Genesis that from that first man up to the incarnation it was always the Son who was seen. If you demand testimonies, you have, of course, the passage in which the Father speaks to the Son, Let us make man to our image and likeness. There follows, And God made man (Gn 1:26-27). Which God made him if not the Son? You yourself have explained this in your treatises.†172 This Son, then, who is the prophet of his Father, also said, It is not good that man be alone; let us make a helper for him like him (Gn 2:18). This Son appeared to Adam in accord with what we read that Adam said, I heard your voice as you walked in paradise, and I hid myself because I was naked. You certainly have what God said to him, And who told you that you were naked unless you have eaten from that tree about which I commanded you that you not eat? (Gn 3:10-11). This God was seen by Abraham;†173 if you are willing to believe, the only-begotten God himself declared in the gospel that the Son was seen by Abraham. He said, Abraham, your father, rejoiced to see my day, and he saw it and he was glad (Jn 8:56). This Son was also seen by Jacob in the form in which he was to come, that is, in the form of a man; he is found to have wrestled with Jacob as a foreshadowing of what was to come. Jacob said, I have seen the Lord face to face, and my life has been preserved, and the name of this place was called The Vision of God. The God, who wrestled with Jacob, foreshadowing what we see fulfilled in the passion of Christ, attested to this. He said to Jacob, Your name will no longer be called Jacob, but your name will be Israel (Gn 32:28), that is, one who sees God. We prove that he was seen in the New Testament as well. The apostles said of him, And we have seen his glory, the glory as if of the Only-Begotten by the Father (Jn 1:14). But, if you claim, as you try to do, that the Father was seen, all the scriptures are for you filled with lies. Paul proclaims that the Father is invisible, and in the gospel the Lord affirms it.

“You often make the accusation against us that we boldly and presumptuously say things that we should not say. That will be up to the judgment of the reader to test. After all, we do not speak to obtain praise from someone, but out of the desire to strengthen the brotherhood we have. Perhaps you wanted to challenge us to make an answer so that those you have observed to belong to us might agree, as I said, with what you profess. For this reason, I had to answer you on account of the fear of God. It was not only by your words that you tried to take from me the discipleship of these men; you also gave me your treatise to which I had to answer those things which you have professed concerning the invisibility of the omnipotent God. Though with another intention, still in your own words, you stated that the Holy Spirit was seen in the form of a dove as well as in the form of fire and that the Son was seen in the form of man, but that the Father was seen neither in the form of a dove nor in the form of a man. He never turned himself into any forms and is never changed. Scripture says of him, I am who I am, and I have not changed (Ex 3:14 and Mal 3:6). The Son who, of course, had already been established in the form of God has, as you have stated, taken the form of the servant, but the Father has not. Likewise, the Holy Spirit took the form of the dove, but the Father did not. Acknowledge, then, that there is one who is invisible; there is one who is incomprehensible and immense. I pray and desire to be a disciple of the divine scriptures; I believe that Your Holiness recalls that I earlier gave the response that, if you produced the evidence that the Father and the Son and the Holy Spirit have one power, one substance, one deity, one majesty, one glory, that, if you state this from the divine scriptures, if you produce any passage of scripture, we are eager to be found disciples of the divine scriptures.”

“I, Maximinus, bishop, have signed this.”

Testimonies of Early Church Fathers In Favor of Sola Scriptura

The early church fathers express a wide range of views on many topics. Issues of authority and how doctrine was to be determined valid, and the role of scripture, like other topics, saw a variety of views. While not necessarily ubiquitous throughout the early church fathers, several fathers ranging from the ante-nicene through post-nicene eras spoke in favor of what is basically ‘sola scriptura’.

They did not, of course, speak of it by that name. In short, for them, it was the principle that in order for doctrines to be established as true, they must be demonstrated from the scriptures. This idea of demonstration is simply that a given doctrinal proposition must be proven from the scriptures, either by way of an explicit testimony, or else as a necessary deduction from them, in order to be accepted by Christians as true. That it come from an esteemed person or an ecclesiastical authority is not enough- it must be demonstrated from the scriptures, these fathers argued.

The first father worth mentioning here will probably come as a surprise in this list to many, Irenaeus of Lyons, because one of the things he is enduringly remembered for is articulating a view called ‘apostolic succession’, which is often appealed to as an alternative to sola scriptura. Certainly to say that Irenaeus believed sola scriptura would be false- but he is worth mentioning here, because even as the father perhaps best known for extolling the importance of ecclesiastical tradition in determining true doctrine from false, yet he also took the effort to write an excellent work, Demonstration of the Apostolic Preaching, in which sets out to prove what the apostles taught from the scriptures. He relies on oral ecclesiastical tradition as his source for what the apostles preached- but then sets out to painstakingly demonstrate each point of what they taught from the scriptures of the Old and New Testaments.

This is noteworthy, because it shows the great value that Irenaeus placed on scripture, and the importance he saw in actually proving the church’s traditions from the scriptures. Were the church alone without the scriptures sufficient to establish the truth of the apostles’ doctrines, one would not expect anyone to bother taking the trouble to go about proving that the various points of doctrine they taught can be demonstrated to be true from the holy scriptures- yet Irenaeus did just that. This shows us that even while Irenaeus held a very high view of the church and her tradition, even he saw it as of great importance to show people that the church’s faith can be known to be true on the basis of demonstration from the scriptures.

The next father we come to is Clement of Alexandria. In Clement of Alexandria’s Stromata, Clement takes up the theme of the ‘true gnostic’. The heresies in modern history known as “Gnosticism” were among the greatest threats that faced the church of his day. The Gnostic heretics claimed that by following the teaching of their various sects, people could gain hidden knowledge of the truth. The selling point of these heresies was that in order to have knowledge of the truth, one must leave the church and go to heretics to receive special esoteric knowledge handed down to them by the apostles. Knowledge of the truth then, was not, according to them, available to all Christians.

Clement responded brilliantly to this by arguing that the true ‘gnostic’ (knower, possessor of knowledge) was the faithful Christian, who gains a true and certain knowledge of the truth by way of demonstration from the scriptures, not those who joined various sects hoping to gain esoteric knowledge. Clement wrote, in Book 7, Chapter 16:

“But those who are ready to toil in the most excellent pursuits, will not desist from the search after truth, till they get the demonstration from the Scriptures themselves… He, then, who of himself believes the Scripture and voice of the Lord, which by the Lord acts to the benefiting of men, is rightly [regarded] faithful. Certainly we use it as a criterion in the discovery of things. What is subjected to criticism is not believed till it is so subjected; so that what needs criticism cannot be a first principle. Therefore, as is reasonable, grasping by faith the indemonstrable first principle, and receiving in abundance, from the first principle itself, demonstrations in reference to the first principle, we are by the voice of the Lord trained up to the knowledge of the truth.

For we may not give our adhesion to men on a bare statement by them, who might equally state the opposite. But if it is not enough merely to state the opinion, but if what is stated must be confirmed, we do not wait for the testimony of men, but we establish the matter that is in question by the voice of the Lord, which is the surest of all demonstrations, or rather is the only demonstration; in which knowledge those who have merely tasted the Scriptures are believers; while those who, having advanced further, and become correct expounders of the truth, are Gnostics. Since also, in what pertains to life, craftsmen are superior to ordinary people, and model what is beyond common notions; so, consequently, we also, giving a complete exhibition of the Scriptures from the Scriptures themselves, from faith persuade by demonstration.” (Stromata, Book 7, Chapter 16)

This excellent quote sums up the patristic doctrine of sola scriptura. It is not a doctrine that denies all ecclesiastical authority; it is not a doctrine that disvalues ecclesiastical traditions and teachers as aids; but it is a true and logically irrefragable principle, that we must be trained in a knowledge of the truth by the voice of the Lord in the scriptures, by seeing all doctrines we hold demonstrated from the holy scriptures. We cannot safely accept any opinion as true merely on human testimony; we must have it from God, in the holy scriptures. This way alone can an actual knowledge of the truth be ordinarily obtained, rather than merely holding uncertain opinions and theories.

Clement of Alexandria’s principle of sola scriptura was not novel to him alone (although it does not seem to have been universally held, either). Cyril of Jerusalem also witnessed to this same principle in the fourth century. His excellent catechetical lectures, which should be required reading for any student of theology or church history, bear several references to this same principle:

“Have thou ever in thy mind this seal, which for the present has been lightly touched in my discourse, by way of summary, but shall be stated, should the Lord permit, to the best of my power with the proof from the Scriptures. For concerning the divine and holy mysteries of the Faith, not even a casual statement must be delivered without the Holy Scriptures; nor must we be drawn aside by mere plausibility and artifices of speech. Even to me, who tell thee these things, give not absolute credence, unless thou receive the proof of the things which I announce from the Divine Scriptures. For this salvation which we believe depends not on ingenious reasoning, but on demonstration of the Holy Scriptures.” (Cyril, Archbishop of Jerusalem, Catechetical Lecture 4)

“For my part, I have ever wondered at the curiosity of the bold men, who by their imagined reverence fall into impiety. For though they know nothing of Thrones, and Dominions, and Principalities, and Powers, the workmanship of Christ, they attempt to scrutinise their Creator Himself. Tell me first, O most daring man, wherein does Throne differ from Dominion, and then scrutinise what pertains to Christ. Tell me what is a Principality, and what a Power, and what a Virtue, and what an Angel: and then search out their Creator, for all things were made by Him. John 1:3 But you will not, or you can not ask Thrones or Dominions. What else is there that knows the deep things of God 1 Corinthians 2:10-11 , save only the Holy Ghost, who spoke the Divine Scriptures? But not even the Holy Ghost Himself has spoken in the Scriptures concerning the generation of the Son from the Father. Why then do you busy yourself about things which not even the Holy Ghost has written in the Scriptures? Thou that know not the things which are written, busiest you yourself about the things which are not written? There are many questions in the Divine Scriptures; what is written we comprehend not, why do we busy ourselves about what is not written? It is sufficient for us to know that God has begotten One Only Son.” (Lecture 11)

“Neither today will we use the subtleties of men, for that is unprofitable; but merely call to mind what comes from the divine Scriptures; for this is the safest course, according to the blessed Apostle Paul, who says, Which things also we speak, not in words which man’s wisdom teaches, but which the Holy Ghost teaches, comparing spiritual things with spiritual. ” (Lecture 17)

“And it is enough for us to know these things; but inquire not curiously into His [the Holy Spirit’s] nature or substance : for had it been written, we would have spoken of it; what is not written, let us not venture on; it is sufficient for our salvation to know, that there is Father, and Son, and Holy Ghost.” (Lecture 16)

Throughout his lectures, Cyril urges his students to test what they hear from ecclesiastical authority by scripture, and accept only what they see demonstrated to be true from it. Likewise, his lectures are replete with admonitions for his hearers to limit themselves strictly to what God has revealed in the holy scriptures, without going beyond it. Only what is demonstrated from scripture is known- therefore, one must limit themselves to those doctrines they see demonstrated.

Cyril taught this in the midst of the raging trinitarian controversies of the fourth century. In that context, he gave clear evidence of his consistency to these principles by refraining from teaching at all on the ‘ousia’ of the Son in relation to the Father, and the nature of the Holy Spirit, instead merely limiting his teaching to his students to what could truly be demonstrated from the scriptures.

Finally, we come to Maximinus the Homoian in the post-nicene era. In the fifth century, bishop Maximinus publicly debated Augustine of Hippo respecting their differing understandings of the Trinity. Throughout the debate, Maximinus constantly appeals to the scriptures as the determinative source of Christian doctrine, rather than philosophical conjectures. As a Homoian, Maximinus’s position seems characteristic of the outlook of the churches among the Vandals and Goths in general; Christian doctrine must be strictly limited to what can be known to be true by way of demonstration from the scriptures. For this reason, the doctrine of the co-essentiality of the Son and Holy Spirit with the Father was deemed to be inappropriate as a part of the Christian dogma- it was a theory which could not, in their view, be demonstrated true from the Holy Scriptures.

These churches held to the decision of the ecumenical councils of Arminium and Seleucia, which declared that:

“the word ‘substance,’ which was too simply inserted by the Fathers, and, not being understood by the people, was a cause of scandal through its not being found in the Scriptures, it has seemed good to us to remove, and that for the future no mention whatever be permitted of the ‘substance’ of the Father and the Son. Nor must one ‘essence’ be named in relation to the person of Father, Son, and Holy Ghost. And we call the Son like the Father, as the Holy Scriptures call Him and teach”

Maximinus echoes this insistence on sticking to what can be demonstrated from the scriptures, and not going beyond that, throughout the debate:

“If you produce from the divine scriptures something that we all share, we shall have to listen. But those words which are not found in the scriptures are under no circumstance accepted by us, especially since the Lord warns us, saying, In vain they worship me, teaching human commandments and precepts” (Mt 15:9).”

“I wanted the decree of the Council of Ariminum to be present, not to excuse myself, but to show the authority of those fathers who handed on to us in accord with the divine scriptures the faith which they learned from the divine scriptures.”

“My reply is clear: I believe that there is one God the Father who has received life from no one and that there is one Son who has received from the Father his being and his life so that he exists and that there is one Holy Spirit, the Paraclete, who enlightens and sanctifies our souls. I state this on the basis of the scriptures. At your bidding, I will follow up with testimonies.”

“The authors of religion never resort to false accusations. You asked for testimonies in order that I might show by testimonies what I have professed, and you yourself have professed three that are the same and equal, the Father and the Son and the Holy Spirit. And, though you professed that the three are equal, you now turn around and produce the testimony of the divine scriptures that pertains not to their equality, but to the singleness of the omnipotent God, that there is one author of all things.†28 You take precedence by your age and have greater authority; hence, go first and show by testimonies that there are three equals, three omnipotents, three unbegottens, three invisibles, three incomprehensibles. Then we would have to yield to these testimonies. But if you cannot give an account of this from the divine scriptures, then I must produce testimonies to the extent that you want for everything I have said in the foregoing: either that the Father alone receives his life from no one or that the Son†29 has received his life from the Father, as I have professed, or what I have said of the Holy Spirit.”

“You yourself are caught doing what you blamed in us. It is certain, as the divine scripture warns us, that with much talking you will not escape sin, but that you will be wise, if you spare your lips. Even if one produces testimonies from the divine scriptures all day long, it will not be truly counted against one as wordiness. But if one uses some literary skill or cleverness of mind and makes up words which the holy scriptures do not contain, they are both idle and superfluous.”

“Those who read can test whether I made this point on my own authority and with many words, as you charge, or whether I have answered with the authority of the divine scriptures.”

“You say that the Holy Spirit is equal to the Son.†91 Provide the scripture passages in which the Holy Spirit is adored, in which those beings in heaven and on earth and under the earth bend their knee to him. We have learned that God the Father is to be adored from the exclamation of blessed Paul, Therefore, I bend my knees to the Father of our Lord Jesus Christ, from whom all fatherhood in the heavens and on earth has its name (Eph 3:14-15). By the authority of the holy scriptures we adore the Father; likewise, taught by these divine scriptures we worship and adore Christ as God. Do the scriptures anywhere say that the Holy Spirit should be adored? If the Father bore witness to him to that effect, if the Son did so, if he himself has made such claims concerning himself, read it from the scriptures against what we have said.”

“We believe the scriptures, and we venerate the divine scriptures. We do not want a single particle of a letter to perish, for we fear the threat that is stated in these divine scriptures, Woe to those who take away or add! (Dt 4:2).”

“We ought to accept all the things that are brought forth from the holy scriptures with full veneration. The divine scripture has not come as a source of our instruction so that we might correct it. How I wish that we may prove to be worthy disciples of the scriptures!”

“I pray and desire to be a disciple of the divine scriptures; I believe that Your Holiness recalls that I earlier gave the response that, if you produced the evidence that the Father and the Son and the Holy Spirit have one power, one substance, one deity, one majesty, one glory, that, if you state this from the divine scriptures, if you produce any passage of scripture, we are eager to be found disciples of the divine scriptures.”

Doctrinal truth, for Maximinus, was to be found in the holy scriptures. Anything not demonstrated from the scriptures, could not be considered to be known, but merely an opinion, and unworthy of being counted a part of Christian dogma.

It is noteworthy, in all these examples, that Clement, Cyril, and Maximinus all had doctrine in view when they spoke of ‘sola scriptura’, and insisted on the Christian principle that all things must be positively demonstrated from the scriptures in order to be accepted as true. In respect to practices, rites, and ceremonies, there is no evidence that these fathers took the same view. There seems to be things in the lectures of Cyril, at least, which would indicate that he was willing to accept various practices on the basis of tradition alone. But doctrine was to demonstrated strictly from the scriptures, and was not to be accepted otherwise.

Such a distinction in principle respecting doctrine compared to practice may have appeared to make more sense in that ancient era. The churches were still relatively close to the apostles, and there may have been greater hope of traditions genuinely reflecting apostolic practice than later eras would have. Regardless of what these fathers thought one way or the other, ordinarily the only way to know with certainty that a given practice is really an apostolic tradition, is to see that demonstrated from the scriptures.

However it is also simply possible that, as many Protestants believe today and since the Reformation, practices were considered by these fathers to fall within the specific purview of the church, and thus, since the church has liberty in such matters, demonstration of specific rites and practices was not considered necessary, as it was with doctrine. Rites, ceremonies, and practices, after all, deal with what is permissible in the life of the church; doctrine deals with what is true and believed by the church. These two different questions, of what is permissible in practice, versus what is true in doctrine, have often been treated as distinct within Protestantism, and there is no reason to think these church fathers were any different, adopting the rites and ceremonies of their times and the churches they were in, while insisting that doctrinal truth required not merely church sanction, but demonstration from the scriptures, so that what is believed can be known to be true, rather than merely supposed.

The doctrine of sola scriptura, then, is certainly no Protestant invention. It is a necessary principle, and one taught by several notable fathers of the ancient churches, that every point of doctrine must be demonstrated to be true from the holy scriptures in order to be accepted. Our beliefs must not, like those of the world, be founded on mere opinion and speculation, but on knowledge; we must be ‘true gnostics’, knowing the truth with certainty because we have seen it demonstrated from the infallible and inspired holy scriptures, and have so been taught it by the Lord Himself.

EDIT 9-18-18: Hippolytus also provides another witness to sola scriptura:

“There is, brethren, one God, the knowledge of whom we gain from the Holy Scriptures, and from no other source. For just as a man, if he wishes to be skilled in the wisdom of this world, will find himself unable to get at it in any other way than by mastering the dogmas of philosophers, so all of us who wish to practise piety will be unable to learn its practice from any other quarter than the oracles of God. Whatever things, then, the Holy Scriptures declare, at these let us look; and whatsoever things they teach, these let us learn; and as the Father wills our belief to be, let us believe; and as He wills the Son to be glorified, let us glorify Him; and as He wills the Holy Spirit to be bestowed, let us receive Him. Not according to our own will, nor according to our own mind, nor yet as using violently those things which are given by God, but even as He has chosen to teach them by the Holy Scriptures, so let us discern them.” (Against the Heresy of One Noetus)
