Yes, I agree that the trinity appears to have been accepted by Christians from the beginning. It would be a lie to say otherwise. I accept the trinity without reservation.
And considering your issue about me not giving Jesus glory, here's what i believe. Jesus is eternally God. Through Him the Father created the world. In Him the world holds together. Somehow, he emptied Himself and came to earth as a man born of mary, yet He was still God. He lived a perfect mortal life, died a sinless sacrifice and was raised up from the grave. He ascended back to the Father and continues to reign as God.
What other glory did you think I was not attributing to Him?
