OK, now I'm confused. We have the Pope calling Mary the "Coredemptrix" and we have at least one Catholic on this thread calling it a heresy.
Nevertheless, I'd believe that the Pope is authorized to speak on correct Catholic doctrine more than any mere Catholic who thinks that they can speak for the Magisterium.
In the service of the Lord,
Christian.
well, I think, like the Samaritans, who meant well, they know not what they worship
The Pope is also free to reflect on things in his own manner without necessarily defining new dogmas for the Church. He can even be wrong (gasp!) in his utterances he does not intend to be binding dogma for the Church for all time.
In this case, I don't think there is much error here except for the inability for some to come to grips with the way Catholics think, beyond bigoted caricature.
