John says nothing about being synonymous with God in someone's eye.
He states Christ our Lord is God.
He has been God from the beginning.
All things were created by him.
..... if you read it that way.
Hundreds of millions of bible-readers don't.
I read the bible for myself, never having been indoctrinated, and never came across the 'trinity'. Nowhere did anything in it say to me 'Jesus is God'. The word for 'him' is the same word for 'it', and can be read as such, and thus, the translation goes 'all things were created by it (God's word)', which is what Genesis says.
That is one perspective, just as yours is another. Many believe in each. Which one is correct? is an irrelevant question at present, because both 'sides' consider ours correct, and can 'prove it' to at least ourselves.
You can believe what you like, as can I. The point is, both beliefs exist, both beliefs can be shown, and both 'sides' are committed.
I've heard the arguments for both a thousand times, and then a thousand more.
This is just more 'my opinion is better than yours'. Christian denominations have struggled and strifed over this for two thousand years and I doubt either of us is highly qualified enough to settle this debate. To be frank, it is a fairly pointless one considering I will only manage to see flaws in your argument as you inevitably will in mine, and we will go nowhere except against one another.
You couldn't change my mind about this if I gave you a month of Sundays, and I'd bet that you feel similarly.
So let's let it lay.
