Sorry, that's not the view of Nicene Christianity. Mary did not bring forth "a man", she brought forth the Lord, Jesus Christ, the only Son of God,
eternally begotten of the Father,
God from God, Light from Light,
true God from true God,
begotten, not made,
of one being with the Father.
Through him all things were made.
For us men and for our salvation
he came down from heaven;
by the power of the Holy Spirit
he became incarnate of the Virgin Mary, and was made man...
You can't separate our Lord into "a man" and God. He is fully God and fully Man.
And that, I think, is where most Prots go foul. They don't really believe in the Incarnation, and that Jesus isn't really God Himself, but rather a man through Whom God chose to work.
