1 Timothy 2:5says that it's the man Jesus, who was the mediator between God and men.
“For there is one God, and there is one mediator between God and men, the man Christ Jesus.” This verse calls Jesus Christ a“man” even after his resurrection. Trinitarian doctrine tries to explain the verses that say Jesus was a man by saying that he was a man, but he was also 100% God at the same time. But there are problems with that such as there is no single verse that says Jesus was both God and man and that's why the God-man doctrine is built from many verses.
Furthermore, scholars admit that there are only about eight verses in the entire New Testament that can be understood to say that Jesus is God, and every one of them can either be translated in a way that supports the Biblical Unitarian position, or disputed textually, or can be explained from the use of the word “God” in the culture. In contrast, the clear verses where Jesus is said to be a “man” such as when Peter or Paul taught their audiences that Jesus was a man appointed by God are not disputed and in the context there does not seem to be any good reason those men would not have said Jesus was a God-man if in fact that is what he is.
