Mary IS the mother of God. One cannot separate Christ’s humanity from his deity. This, in fact, is what raised the issue of Mary’s role at the Council of Chalcedon.
People came to the orthodox conclusions about Mary because of what was known by the orthodox to be true about Christ, but was denied by the Arians and others.
Marian doctrines always have Christological issues at their core; they’re not promulgated merely to magnify Mary further.
You don't have to to make the argument.
P-J, you said: Mary IS the mother of God.
Show me chapter and verse where Mary is refered to, word for word, as “the mother of God”.
What Mary was mother to died. Diety doesn’t die, not even for a second. God was IN Christ. God is a Spirit. God the Father was in Christ doing the miracles.
P-J, you also say: One cannot separate Christ’s humanity from his deity.
AR gives you no arguement, but I will.
Christ DID separate his humanity from his diety.
That was the power in the Christ that enabled him to lay down his life, and take it back up again.
Consider the testamony of Peter to Cornelius in Acts 10:34-43: “..How God anointed Jesus of Nazareth with the Holy Ghost and with power....for God was with him....Him God raised up the third day....it is he which was ordained of God to be the Judge of quick and dead”. That’s how Jesus Christ can say: “All power is given unto me in heaven and in earth”.
Mary was given the great honor of giving birth to the human that God would give his Spirit to without measure. John 3:34
Yet, Mary did not give Jesus Christ any power whatsoever; and therefore is not “the mother of God”.
