Saint Thomas' Doctrine of the Trinity

At the request of a brother seminarian, I'm going to try to put in concise terms my understanding of St. Thomas' teaching on the Trinity. I'm mostly posting this here to remind myself that I had set out to do this so that when I come across this months after forgetting this project, I may then resume. Yes, I think it may be a very long time before I finish, and I have great doubts that I will. I think the final project will be very short if it comes out and perhaps obscure due to my attention to things I find interesting rather than to what is most essential. May God bless my endeavors nonetheless! Saint Thomas, pray for us!
