Christ is our saviour, and he reconciles to God through the gospel, although the word is not his own, he says this himself. But what he speaks he receives from the father and only speaks what the father gives him to speak.Jesus is the way, the truth and the life and the only way to the father is through him.
As you say, it says in the Bible there is only one mediator between God and man and our mediator is the man Christ Jesus. So Christ isn't God as he is the mediator between us and God. And when we pray we pray to the father through him, everything is now done through Christ, because God has set Christ at his right hand and has given him authority over everything in heaven and in earth.
But I would have you know that the head of every man in Christ and the head of the woman is the man and the head of Christ is God. (1 Corinthians 11:3).
Aren't God and Christ actually titles and positions that have meaning? My point being is that in a sense God may not be Christ and Christ may not be God, in the same sense that Sheriff is not Judge and Judge is not Sheriff. The point being here is that while roles may not be identical to each other, the same person might fill both roles.
Jesus can be both LORD and Christ.
