The absolute giant leap that is made by the Roman Catholic Church is that THEY have the authority to do what is commanded in Matthew. They are co-opting the power of Christ’s blood to hold men hostage. It may surprise some Roman Catholics to learn that Christ’s words about “never knowing you” were not exclusively directed to those who don’t surrender to the Roman bishop.
Quite the opposite in fact. The Catholic Church is insuring that the proper matter and form are being used. Think of it this way: A surgeon must use specific tools in the proper manner for a surgery to be successful. While it might be successful to "MacGyver" it, why take the chance.
