Well that's news to me! No true Christian teaching can contradict the Bible, and no teaching that isn't in the Bible is binding on the conscience of true Christians.

Hardly. The Trinity is a fundamental doctrine of Christianity, but is never mentioned in the Bible.

It is the answer to a paradox: if Jesus is a God, and his father is a God, but the OT claims there is only one God, how can this be?

The answer adopted by the Church is the Trinity. It is important to note that it is an logical extrapolation and not expressly described anywhere in the Bible.

How about "in the beginning was the Word of God, and the Word was with God"

Uh, maybe it is... check here One God or three?

You're party right, partly wrong.

Although the word 'trinity' is not found in the bible, neither an overt discussion about the concept, the existence of the trinity is still fully supported in both the Old and New Testaments.

If you're truly interested in what the Bible has to say, and don't mind doing a little reading as homework, I can recommend the following article by Arnold Fruchtenbaum, and Jewish man who recognizes Jesus as the Messiah. He's laid out the proofs of the trinity as well as anyone I know:

The Trinity, Part One by Arnold Fruchtenbaum

The Trinity, Part Two by Arnold Fruchtenbaum

Besides this article, there are tons of discussions and studies outling why we believe in the three persons of the trinity who are the one true God. Continue to do research and you will find a lot of good reading.

Of course, if you're not interested in what the Bible has to say, but merely want to spout your unfounded, unresearched opinions as fact, you can do that, too.
