Sir Isaac Newton is well-known for his scientific contributions, but his Christian theology is far less well-known. Although Newton never published his beliefs during his lifetime, he spent an enormous amount of energy studying the scriptures, church history, historical theology, and specifically, the doctrine of the Trinity. Interestingly, he appears to have come to many of the very same conclusions I have regarding the developments taking place in the Nicene era, and to have come to many of the same doctrinal conclusions I have as well.
Because Newton didn’t publish his views on doctrine, the large body of primary sources we have on his beliefs primarily come from his own personal notes. These are not easily available, and as such, finding reliable information on what he actually believed has been a task I have found somewhat difficult.
Thankfully, this essay gives a thorough overview of Newton’s beliefs, and is rich with quotations from the primary sources. The author’s analysis is also cogent and thought-provoking. I highly recommend this, for those who are interested:
