Whatsoever then you have well in this world, when you recollect to have done any thing good, be very fearful about it, lest the prosperity granted you be your recompense for the same good. And when you behold poor men doing any thing blameably, fear not, seeing that perhaps those whom the remains of the slightest iniquity defiles, the fire of honesty cleanses.
Pope Gregory IYou cannot acquire the gift of peace if by your anger you destroy the peace of the Lord.
Pope Gregory IAs long as the vice of gluttony has a hold on a man, all that he has done valiantly is forfeited by him: and as long as the belly is unrestrained, all virtue comes to naught.
