You are making a hasty and wrong conclusion. I affirmed Jesus is God, but the issue remains the use careful use of titles. Thus Jesus is called Lord and God. Again, Lord primarily refers to what He is as ruler, and can be applied to mortals and the Messiah after the Jewish expectation, but God denotes His being, and Mary is never termed Mother of God, though again, that may be technically allowed in a sense (as would Mary’s mother being the grandmother of God by extension, and so on).
Likewise, Co-redemptrix can be technically allowed in a sense, but both are unnecessary, and easily infer more as part of the excess extrapolated exaltation of Mary, as overall seen here. http://www.freerepublic.com/focus/religion/2841954/posts?page=187#187
2)Did Mary give Birth to Him, Yes or no?
Notice I am not in any way asking if Mary is divine Clearly she is not, and there is not a sane rational person that in any way thinks she is. I am not asking if she contributed to His humanity, or his divinity. I am asking if she gave birth to the second person of the Trinity that we all know as Jesus.
