Sorry jaybird, but you are uninformed. The doctrine of the Trinity as we know it today dates back well BEFORE the 1st century. It is deeply rooted in the normative theology of the Second Temple era Judaism dating back to 500 BC and is ultimately revealed in the New Testament and gradually ARTICULATED in respons to the attacks of heretics.
In the Aramaic Targums which was the common language translation of the Old Testament, used by Jesus Christ and his disciples, the personal appearances of YHWH were IDENTIFIED with, "the Angel of the Lord" and identified as, "the Word" of the Lord, (Aramaic; the Memra).
When the Apostle John wrote in the first verse of his gospel, "and the Word was God", he was NOT invenbting a new theoilogical concept. He was simply stating what was already ovvious to informed Jews of the time, though he used the Koine Greek cognate for "memra" and that is "logos", the "Word." His ultimate point, however, is that the One identified as "the Wor4d" is the One who ultimately became flesh and dwelt among us" (John 1:14) Jesus of Nazareth. Obviously you are unaware of this fact and it is hardly new.
While this is not a fully articulated trinitarian doctrine, it IS the ancient, pre-Christ5ian root of the trinitarian revelation which antedates Christianity itself and ultimately became the definitive theology, which distinguishes authentic, apostolic, biblical and ultimately ORTHODOX, 1st century Christianity. The ancient Jewish theology of "the intermediary" greatly antedates and obviates the 19th century unitarian theology of today's CULTS. But the doctrine of the trinity was indeed represented by 1st centure Christian writers who, along with the Bible itself, simply RECOGNIZED that there is ONE God, while explicitly identifying that ONE God as three persons. It was Tertullian that formulated the word "trinity" at around 200 A.D. well before these so-called councils of Rome met.
This is one of the reasons I started the two threads on "Who is Jesus Christ," "Can the Trinity be Biblically Proven" and my thread on "Who is the Angel of the Lord." As I keep saying, please check out what I'm saying with what the Bible teaches. I am not (like you and some others around here) just giving my opinions on issues. Do your homework!
IN GOD THE SON,
