Here is a lesson in traditional theology:
Jesus Christ was both completely human and completely divine at the same time. He was both a human being and the eternal Logos (the Word). He had two natures.
God does not have a mother. But Jesus Christ did, because he was both of man and of God.
The Logos was not concieved in Mary’s womb, but Jesus Christ was, because in him, God and man were united together in one body in order to save and redeem mankind
I don’t disagree with your lesson. I do agree with your statement “God does not have a mother.” Jesus did have a mother. Amen to the Lamb of God.
