Is Jesus God in John 1:1 That Says “and the Word was God”?

If yes, then there are two Gods in the passage: Jesus and the God who was with him. And with that, Christianity ceases to become a monotheistic religion anymore, but a polytheistic one.

Could this be explained away by that mind-boggling doctrine called trinity which is not in the bible?

The book offers two clean interpretations, both of which do not undermine the oneness of God.
