Yes, He pre-existed the world. Yet, once He was conceived by the power of the Holy Spirit in the womb of Mary, He became fully human AND fully divine. "Mother of Jesus" is accurate, but what is Jesus? He is true man, but also true God. The title "Mother of God" comes from a time in Christian history when there was a debate over whether Jesus was two distinct persons in one body, or whether He was one person with two natures. The Council of Ephesus decided upon the latter when it gave Mary the title "Theotokos" (literally "God bearer,") which was translated as "Mother of God"). When a woman bears an unborn child naturally, that woman becomes a mother.
>> I am not sure what you mean by the "jury is out" if its dogma isn't that what the official teaching of your church is? <<
I think what Pyro means is that the jury is still out as to whether Mary died, and was immediately assumed into Heaven before her body experienced a trace of corruption (i.e., rotting), or whether she was assumed into heaven while she was still living. I always presumed it meant while she was still living, but I can't think of anything contradictory to the notion that she died and was immediately assumed, other than some speculation that she was one of whom Jesus said would not taste death before the establishment of the Kingdom on Earth... but I also understand that quote is often held to refer to the establishment of the Church.
>> Mary did not create GOD. <<
No one has ever understood it to mean that.
>> By your definition of "Co-Redemptrix" the soldiers who forced JESUS to carry the cross were Co-Redeemers because they assisted in the redemptive act. <<
No, that's an unnecessary detail that could have played out in many other ways without affecting the nature of his time on Earth; I would say that by that definition, however, anyone who assisted in someone's conversion is a personal co-redeptor to the convert, and I have no reason to believe the church would object to that being stated, either.
>> However, I don't believe either should be elevated to a status that is equal to our mutual LORD and SAVIOUR. <<
Again, that is not what any Catholic understands that to mean.
Awesmome post!! Keep up the good work.
