I know the word "Trinity" is not found in the Bible. To be crystal clear, I am most interested in the genesis of the formation and trinitarian teachings. Any references to a book, websites, quote of the fathers, etc., would be helpful.

Please share the historical facts with some references, please! If you are not sure or have historical facts, feel free to pass this thread. At least, for this thread, take a little time and do some research before responding. I would appreciate it greatly. It's alright if you don't have anything concrete to add at this time. When you do so, please share, in light of what is requested.

What are the basics of the Athanasian Creed? Is this the creed upon which the entirety of the Roman Catholic faith is built? Does the Athanasian Creed (Roman Catholic Creed) say that the one God is three divine personalities in one indivisible substance or essence?

The three in one God idea came from Athanasius, whose teacher was Origen, who “believed in the doctrine of Purgatory, transubstantiation, transmigration of the soul and reincarnation of the soul. The Scriptures were not literal.” — (See Dr. Ken Matto, Origen's Gnostic Belief System). Happy searching. CM
