But now, coming to your shameless assertion that ministers of the altar should be allowed to marry, I consider it superfluous to unsheathe the sword of my own words against you, since we see the armed forces of the whole Church and the massed array of all the holy Fathers ready to resist you. And where so great a host of heavenly troops opposes you, one can only wonder that your novel and rash attempt at doctrine does not submit when confronted by such authority.
