Today is the Feast of Our Lady of Guadalupe. The story goes that the Blessed Virgin appeared to the indigenous Juan Diego in 1531 near Mexico City. What has always fascinated me about this story (and there were always representations of her in our house, thanks to our Mexican-American Catholic mother) is that she appeared not as a European queen but as a beautiful Aztec princess.
Now, I've discarded much of the extraneous Catholicism I grew up with but I still cross myself when receiving communion and still bow my head when we recite the Apostles' Creed in worship at the phrase, "Who was conceived by the Holy Ghost, born of the virgin Mary." In my finite understanding, there is a big difference between being the Mother of the Son of God and being the Mother of God. I hold to the former, not the latter.
That being said, it seems to me that some non-Catholics, in their zeal to distance themselves from Roman Mariolatry, almost denigrate Mary. I think she is due respect and reverence, not as a co-mediatrix or co-equal but because God chose her to bear the Saviour.
That's just my opinion.
