By these words it is surely shown that in his [the rich man] daily feasting he had frequently sinned by his tongue, seeing that, while burning all over, he demanded to be cooled especially in his tongue. Again, that levity of conduct follows closely upon gluttony sacred authority testifies ... For the most part also edacity leads us even to lechery, because, when the belly is distended by repletion, the stings of lust are excited.
St. Gregory the Dialogist
The Book of Pastoral Rule, Chapter XIX, 6th century
The man who has once chosen pleasure in this life, and has not cured his inconsiderateness by repentance, places the land of the good beyond his own reach; for he has dug against himself the yawning impassable abyss of a necessity that nothing can break through.
St. Gregory of Nyssa
What is it that I love when I love you? Not the beauty of a body or the comeliness of time. Nor the luster of the light pleasing to the eyes, nor the sweet melodies of all manner of songs, nor the fragrance of flowers, ointments and spices, not manna and honey, nor limbs welcome to the embrace of the flesh - I do not love these when I love my God. And yet there is a kind of light, a kind of voice, a kind of fragrance, a kind of foods, a kind of embrace, when I love my God, who is the light, voice, fragrance, food, embrace of the inner man, where there shines into the soul that which no place can contain, and there sounds forth that which time cannot end, where there is fragrance which no breeze disperses, taste which eating does not make less, and a clinging together which fulfillment does not terminate. It is this that I love when I love my God.
St. Augustine
Confessions 10.6 in The Confessions of St. Augustine, p. 244, 5th century
How then is it possible for the rich man to be saved. By possessing his goods in common with them that are in need, being such as Job was, and exterminating out of his soul the desire of more, and in no points going beyond real need ....
St. John Chrysostom
Homily 74 on Matthew 23; Homily 78 on Matthew 6, 20, 25, 4th Century
For if any one becomes wholly and thoroughly carnal in thought, such as one with every motion and energy of the soul absorbed in fleshly desires, is not parted from such attachments, even in the disembodied state; just as those who have lingered long in noisome places do not part with the unpleasantness contracted by that lengthened stay, even when they pass into a sweet atmosphere.
St. Gregory of Nyssa
