"A stumbling block to conversion for many Protestants has long been Catholic Marian devotion. This reform deflects attention from Mary to Christ, so it would supposedly have more appeal for those contemplating conversion."The point is that it isn't just the Marian worship that is a stumbling block. It is the praying of a rosary no matter who you are reflecting on. It is the prayer to the saints and the lost souls.
To think that someone grounded in his faith would change because of redirecting of rosary prayers is absurd.
The differences between the Catholics and the Protestants are much deeper than what this so called theologian claims
I don't disagree with you. The differences are great, but the trend in the post-conciliar Church has been to obscure the differences in the hope that Protestants will become Catholics. From what I can see, the opposite is happening. Catholics are gradually becoming Protestants.
