This brings us to a basic theological question. Jesus Christ was the only person ever born with two natures, one human and one divine. He was but one person however, not two. He could not be a human person and a divine person, as that would make Him two persons. Jesus Christ is a divine person.
Mothers give birth to persons, each with a nature.
They do not give birth to natures. Yes, she is a mother like any other mother, but what a difference between the sons. We have established that Jesus Christ is GOD, that He was born of Mary, and that GOD needed her for this 'Incarnation'. Let us look at what Scripture says. Jesus Christ did not come to destroy the 'Law', but to fulfill it.
