Gregory the Great

Wherefore, lest either gluttonous appetite throw the one sort off their guard, or the afflicted flesh trip up the other by elation, let the former hear this from the mouth of the Truth, "And take heed to yourselves, lest at any time your hearts be overcharged in surfeiting and drunkenness and cares of this world." And in the same place there is added a profitable fear; "And so that day come upon you unawares. For as a snare shall it come on all them that dwell on the face of the whole earth." Let the latter hear, "Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man." Let the former hear, "Meat for the belly, and the belly for meats; but God shall destroy both it and them." And again, "Not in rioting and drunkenness." And again, "Meat commendeth us not to God." Let the latter hear, "To the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure." Let the former hear, "Whose God is their belly, and whose glory is in their own confusion." Let the latter hear, "Some shall depart from the faith;" and a little after, "Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth." Let those hear, "It is good neither to eat flesh nor to drink wine, nor anything whereby thy brother stumbleth." Let these hear, "Use a little wine for thy stomach's sake and thine often infirmities." Thus both the former may learn not to desire inordinately the food of the flesh, and the latter not dare to condemn the creature of God, which they lust not after.
