Pope Innocent III

“ Certainly just as heretical depravity should not be tolerated, so religious simplicity should not be considered a weakness; lest either our patience makes heretics bold, or lest great impatience confuses simple men, so that when we are in disagreement, they are turned into a crooked bow [4] , and they are transformed from simple men into heretics. ”

“ Just as it is incumbent upon prelates of the church to seize young foxes, who try to destroy the Lord's vineyard [2] , it is incumbent upon them to listen prudently and diligently: thus they should guard very strongly against collecting the cockle before the harvest, lest perhaps, God forbid, the wheat is also taken up with it. ”
