And, before Jesus was made flesh, he had no humanity. Mary gave birth to the humanity of Jesus Christ and now he is STILL in the glorified body that, one day:
Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. (I John 3:2)
How does a mother give birth to one person who is both God and man, divine and human and only give birth "to the humanity"?
Do you see the error about who Christ is that is in this statement about Mary?
