Give it a little bit of time. From Catholic Online:
"There’s another well-known Catholic who also calls the Mother of Jesus the Co-redemptrix: His name is Pope John Paul II. He has done so on six occasions during his post Vatican II pontificate."So, was John Paul II speaking ex cathedra or was he speaking as a fallible human being? Was his well-known devotion to Mary a signal on the direction that the RC church would ultimately take or was it heresy? If the RC church decides to reject the notion of Mary as co-redemptrix, then you have the problem of one of the most popular popes in history being a heretic.
By the way, I admired Pope John Paul II greatly for many reasons but found his extreme devotion to Mary quite frightening. The Bible, which is supposedly one of the three legs of the footstool that is the RC church, is most explicit that our worship, prayers, and devotion belong only to the triune God and not to any other.
The apostle John records this caution about bowing down to or giving more credit to angels (or anyone) than is due: "And I fell at his feet to worship him. But he said to me, 'See that you do not do that! I am your fellow servant...'" (Revelation 19:10, see also Revelation 22:8-9). I think that if someone with a devotion to Mary actually met her, she would tell them the same thing.
We're in an agreement with this one. If they did so with the intention of worshipping her as a goddess, then she would do so.
Perhaps showing how the Catholic Church defines "co-redemptrix" would be helpful at this point?
