DID the early Christians teach the Trinity?

I don't know if it did or not. Quite frankly, I think this is another of the "man's interpretation" things that has cause us to have so many different religions. Keep in mind, that no where in the Bible does Christ or God ever state that their had to be a specific group of doctrines in order for people to follow Christ. The only real doctrine in the belief in Christ as the Savior. (By the way, I was raised Lutheran)
