If they allowed priests to marry, two things would happen:
They would get more priests
These priests would flush out paedophiles
Point 1: Celibacy has little to do with vocations. If seminaries didn't discourage orthodox young men from attending, there would be plenty of aspirants to the priesthood. Too many seminaries are still in the grip of modernism.
Point 2: Celibacy doesn't have anything to do with child molesters. There are too many examples of MARRIED child molesters to debunk this notion. In fact, in studies that have been done in the last couple of years, it has been found that the instances of abuse in the Catholic church in America were no more prevalent than instances in other denominations, or in public schools. It also found that other organizations were no more forthcoming about this abuse than the Church was. It just so happened that the Church got tons of press, while the other organizations did not.
