Ancient Monarchians and Trinitarians

BobDylan

1. The fully developed doctrine of the trinity was referenced in these early church writing from the first two centuries... (writing a., writing b. and writing c.)...

The trinity was first referenced by Justin Martyr and Tertullian in (I think) the 2nd century...

I would argue that even today there is no such thing as "fully developed doctrine" because even to trinitarians it isn't the most sensible statement (3 persons in 1 person, etc.)

2. The doctrine of the trinity was established as the official dogma of the "real" church (by that time the Roman Catholic chruch) by the Council of Constantinope in 381 AD....

it was officially adopted in 325 AD at Nicea and added to in 381 at Constantinople...

both to eliminate Arians (it didn't work in 325)... Both to confirm the oneness of God...

3. Between the years of 400AD to 1500AD the real believers were called _________ and were located ________ (etc. etc. etc.)

This isn't answerable by him or you... HOWEVER, the way the church structure worked, there was never universal absolute agreement between "churches" (read: cities) until much later... Really, not even today is there completely 100% agreement between churches in different regions within the Roman Catholic Church (and that isn't even including the Greek Orthodox and Russian Orthodox and all the other Catholic splits that exist)...

It would be really easy for a church to preach what most Protestant groups preach by and large thorugh most of the dark ages and not get found out...

I'm not sure they could have preached what we preach and not been found out, though....

(I know these weren't addressed at me, but I'm really interested in this topic and have wanted to jump in for a couple days now...)
