There are in truth three states of the converted: the beginning, the middle, and the perfection. In the beginning they experience the charms of sweetness; in the middle the contests of temptation; and in the end the fullness of perfection.
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.
Pope Gregory IObedience is the only virtue that plants the other virtues in the heart and preserves them after they have been planted.
Pope Gregory IThe more the wicked abound, so much the more must we suffer with them in patience; for on the threshing floor few are the grains carried into the barns, but high are the piles of chaff burned with fire.
Pope Gregory IThere is more joy in heaven over a converted sinner than over a righteous person standing firm. A leader in battle has more love for a soldier who returns after fleeing, and who valiantly pursues the enemy, than for one who never turned back, but who never acted valiantly either. A farmer has greater love for land which bears fruitfully, after he has cleared it of thorns, than for land which never had thorns but which never yielded a fruitful harvest.
Pope Gregory I
