You are right. Though, in my mind, even Mary was just a vessel and more of a foster mother. Though, I guess it's only a matter of technicalities and semantics really.
I wouldn't say that Jesus saying, "I am the son of man" means that God is a man. That's what some cults think. And they think that because they want to be as God is like satan did. No, Jesus is son of man and Son of God. Right?so to Jesus to say i am the son of man,means that God is a man.
Jesus is God in the flesh.so to Jesus to say i am the son of man,means that God is a man.
