Fascinating. We all interpret and emphasize things a little differently I guess, but I definitely see the relevance of Constantine and the Arian priest (Arianism by the way is totally different from Aryanism but I think others have defined that already) Constantine and Arius, for whom Arian doctrine was named, as a HUGE part of early Christian history and early Church history. Had the councils ruled differently, in favor of Arius, for example, the Church would have taught non-Trinitarian doctrines. Please read the book When Jesus Became God: The Struggle to Define Christianity during teh Last Days of Rom but Richard E Rubenstein. 1999 by Harcourt Press. It's a fascinating and well documented account of how the early church arrived at and settled on the doctrine of the Trinity, the controversy, the organizational politics and the Roman empire politics, the machinations, schemes, etc. Regardless of your theological position, and your committment to it, please do read it, it explains so much and will fill you in on why people are saying all these things in contrast to your beliefs. Plus the historical narrative is just so interesting.
