But, Buggman, that's precisely what God himself did by by becoming incarnate as her Son. Scripture itself says that Christ returned to Nazareth and "was subject to them [that is, to Joseph and Mary]".
God was under Mary's authority, though probably not in the sense that you were thinking when you wrote your comment.
Hey Campion, I already addressed that point back in posts #49 and 51. As a human child, He was put under her authority. As the Resurrected Lord, she is back under His.
Luke 2:
48: And when they saw him they were astonished; and his mother said to him, "Son, why have you treated us so? Behold, your father and I have been looking for you anxiously." 49: And he said to them, "How is it that you sought me? Did you not know that I must be in my Father's house?"
50: And they did not understand the saying which he spoke to them.
51: And he went down with them and came to Nazareth, and was obedient to them; and his mother kept all these things in her heart.
52: And Jesus increased in wisdom and in stature, and in favor with God and man.
Certainly you don't think it is possible for God to "increase in wisdom..."?
