Jerome
Patristic
c. A.D. 347–420
“By a threefold confession Peter blotted out his threefold denial. If Aaron committed sacrilege by fashioning molten gold into the head of a calf, his brother's prayers made amends for his transgressions. If holy David, meekest of men, committed the double sin of murder and adultery, he atoned for it by a fast of seven days.”
