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 IBecause God that is immutable changes what He willed, He is said to repent, although what changes is a thing and not His counsel.
Pope Gregory IThe pastor should always be pure in thought ... no impurity ought to pollute him who has undertaken the office of wiping away the stains in the hearts of others ... for the hand that would cleanse from dirt must be clean, lest, being itself sordid with clinging mire, it soil whatever it touches all the more.
Pope Gregory IWhoever wishes to hold the fortress of contemplation must first of all train in the camp of action.
Pope Gregory INow if the wearing of fine and precious robes were not a fault, word of God would never have so carefully expressed this. For no one seeks costly garments except for vainglory, that he may seem more honorable than others; for no one wishes to be clothed with such, where he cannot be seen by others.
Pope Gregory I
