You already know this...John 8 'Before Abraham came to be, I am'. Obviously Jesus was born after Abraham, right?
And of course, John 1 'In the beginning was the Word, etc, 'and the Word became flesh'.
Well, John 8 has been interpreted by 'before abraham, I am '(in priority). Different translations come up with different senses. The 'in priority' translation makes better sense.. Of the other points about I AM when it ocmes to time sense, the arians believe he was just responding the the asserstion that he wasn't old enough to have seen abraham.. . One point.. the 'ego emini' being used is not the 'divine' 'ego emini on ho' that was used by God.
As for 'Logos', I think the gnostics got it right there. Logos is talking about the 'wisdom of god', not god itself. That is the concept that was brought to the table by Philo Judas when he melded the "Logos" of the greeks with jewish concepts in about 30-40 ad. If you read John in a non-tritarian terms, Jesus is "the one sent".. the wisdom of god. Not God.
I personally think that the Trinity is a way to keep the idea of Jesus being God,and the 'god is one'. I think it is hard to explain because
it just doesn't make sense.
