“If you address as Father the One who impartially judges according to each one’s work, conduct yourselves in fear during the time of your stay on earth;” 1 Peter 1:17 NASB
“For not even the Father judges anyone, but He has given all judgment to the Son,” John 5:22 NASB
Here we read from Peter, firstly, that the Father judges men impartially; then we read from John, that the Father judges no one, but has given all judgement to the Son. Is there disagreement between Peter and John? Does scripture contradict itself? Not at all; but rather, the difficulty is resolved when we read “Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, 31 because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.” Acts 17:30-31 NASB; and, “And He [the Son] commanded us to preach to the people, and to testify that it is He who was ordained by God to be Judge of the living and the dead.” Acts 10:42 NASB
What we have then, is this: scripture says that God, the Father, judges all men; and yet, in another place, it says He judges no one at all. Unless we will say that these statements contradict one another, we must acknowledge each to be speaking in a different sense; one speaks of God judging all men indirectly through Christ, through Whom are all things 1 Cor 8:6. The Father is the ultimate Cause of all judgement, and all judgment is according to His will and command, although it is executed through the Son. And so the Son said “I can do nothing on My own initiative. As I hear, I judge; and My judgment is just, because I do not seek My own will, but the will of Him who sent Me.” John 5:30 NASB. The Father then may truly and rightly be said to “impartially judge according to each one’s work”, because He so judges mediately, through the Son, Who judges not on His own initiative, but according to the will and command of the Father.
On the other hand, the Son has all judgement given to Him by the Father, and the Father judges no one, in this second sense, in reference to immediate action, since the Father immediately judges no one, but all immediate judgment is given to the Son. For the Son clearly says that He does not judge according to His own initiative but according to the will of the Father; and so the Father judges through the Son, and so, Himself truly judges all- not immediately and directly, but mediately, through the Son, the one Mediator between God and man. Meanwhile the Son alone judges immediately and directly. Since all things from God through Son, so God judges through Son, the Son judging according to the will and command of the Father. The Son alone, however, judges immediately, and in that immediate sense, God judges no one.
We can apply this same sort of logic reasonably to all things that God does through His Son. So there is shown a significant difference between the actions of God and of His Son towards creation; the Father acts towards creation mediately, the Son both immediately, and through the Holy Spirit. The Holy Spirit only acts immediately towards the universe, never through another person of the Trinity. So the actions of the persons are not entirely identical, but each acts towards creation differently and distinctly. This shows that the Father, Son, and Holy Spirit are distinct individual beings, or persons.
In all this we still see that the persons are united in their actions; the one God, the Father, works through His only-begotten Son, and the Son through the Holy Spirit. This is the pattern of all God’s great works toward the universe: all things are from Him, through His Son. “Yet for us there is one God, the Father, of whom are all things, and we for Him; and one Lord Jesus Christ, through whom are all things, and through whom we live.” 1 Corinthians 8:6 NKJV. God created the universe through His Son; God upholds the existence of the universe through His Son; God rules over all things through His Son; God reconciles all things to Himself through His Son; and as we read above, God judges the world through His Son. In the immediate and most high sense, as being the Supreme Cause and Instigator of all these things, the Father is the one Creator, the one Sustainer, the Only Ruler, the Only Savior, and the one Judge of the universe; performing all these actions through the mediation of His Son.
And in the same manner as that judgement was spoken of, we might reasonably speak of any of these acts of God; God, the Father, alone in truth performing all these actions, not immediately and directly, but through the mediation of His only-begotten Son, Who acts upon the universe directly and immediately, according to the will and command of the Father. And so the Son, and not the Father, is the immediate Creator, Sustainer, Savior, and Judge of the universe; in this immediate sense the Father creates no one, sustains no one, saves no one, and judges no one, in the whole of the universe that is through His Son. And so, we see the distinct roles of each person; and we see that although God acts through His Son, and His Son acts on His behalf, and according to His will and command, the roles, and so, the actions, of each person, within these greater works are distinguished from one another.
We cannot speak of the Father as the immediate worker of any of those works; nor can we speak of the Son as the ultimate cause of any of those works. The Father alone is the one from Whom are all things; and the Son alone the one through Whom are all things. Therefore the actions of the persons are shown to be distinct and different; the one working mediately and indirectly, the other working immediately and directly on the universe. As mentioned earlier, this distinction in action proves that God and His Son are distinct persons; the Father, the one God, and His only begotten Son, the Lord Jesus Christ, are two distinct rational individual beings, not one and the same. Otherwise, if They were the same, one could not be said to do something through the other; and one could not be said to be the one from which an action was, the other the one through Whom an action was performed, unless They are two really distinct persons.
