“But before the baptism let the baptizer fast, and the baptized, and whatever others can; but you shall order the baptized to fast one or two days before. But let not your fasts be with the hypocrites; Matthew 6:16 for they fast on the second and fifth day of the week; but fast on the fourth day and the Preparation (Friday).”
— Didache (80–140)
Chapters 7–8
“Every prayer should be accompanied with humility: fast, therefore, and you will obtain from the Lord what you beg.”
— Hermas (150)
Book 1, Vision 3, Chapter 10
“When, indeed, have not droughts been put away by our kneelings and our fastings?”
— Tertullian (212)
To Scapula, Chapter 4
“No one shall find fault with us for observing the fourth day of the week, and the preparation, on which it is reasonably enjoined us to fast according to the tradition. On the fourth day, indeed, because on it the Jews took counsel for the betrayal of the Lord; and on the sixth, because on it He himself suffered for us. But the Lord’s day we celebrate as a day of joy, because on it He rose again, on which day we have received it for a custom not even to bow the knee.”
— Peter of Alexandria (310)
Canonical Epistle, Canon 15
“But let not your fasts be with the hypocrites; for they fast on the second and fifth days of the week. But do you either fast the entire five days, or on the fourth day of the week, and on the day of the Preparation, because on the fourth day the condemnation went out against the Lord, Judas then promising to betray Him for money; and you must fast on the day of the Preparation, because on that day the Lord suffered the death of the cross under Pontius Pilate.”
— Apostolic Constitutions (390)
