WHY FASTING?
Orthodox fasting joins prayer and almsgiving in repentance, training desire and making room for mercy. Its communal calendar helps people practice together; its application is adapted through pastoral guidance to health and circumstance.
Historical context
Jesus and the apostolic Church fasted. The Didache describes a regular communal rhythm, but its particular days should not be confused with the full later Orthodox fasting calendar.
Avoid overclaiming
The Didache's weekly rhythm is not the whole later Orthodox fasting calendar. Historical evidence is not personal medical or dietary advice; health, age, and circumstance require appropriate pastoral and professional guidance.
Strongest alternative reading
Catholic and many Protestant traditions also fast, with different calendars and disciplines. The dispute is often about the binding character of particular rules and their pastoral application, not whether fasting ever belongs in Christian life.

Primary sources
The Didache directs:
The Didache witnesses to a shared early Christian rhythm of Wednesday and Friday fasting.
but fast on the fourth day and the Preparation (Friday)
Passage context and translation
This community rule witnesses to a weekly fasting pattern; it is not evidence that all ancient Christians followed one universal calendar.
Before the excerpt
for they fast on the second and fifth day of the week
After the excerpt
Neither pray as the hypocrites
Didache 8 places the Lord's Prayer in a daily rhythm and names Wednesday and Friday fasts.
Thrice in the day thus pray.
Passage context and translation
The instruction follows the Lord's Prayer. The chapter also names fasts on the fourth day and Preparation, conventionally Wednesday and Friday. Its contrast with 'hypocrites' reflects ancient communal polemic and must not become a general judgment on Jewish people or Jewish prayer.
Didache 15 explicitly brings prayers, alms, and deeds under the gospel's instruction.
But your prayers and alms and all your deeds so do, as you have it in the Gospel of our Lord.
Passage context and translation
The chapter treats local ministers, peaceful correction, repentance, prayer, almsgiving, and deeds. This closing sentence places the community's conduct under gospel instruction.
Augustine directs both the teacher and the learner toward love as the aim of instruction.
the end of the commandment, which is charity, out of a pure heart, and a good conscience, and faith unfeigned
Passage context and translation
Augustine advises a catechist how to narrate the scriptural history without exhausting the learner. He directs the teacher's and learner's attention toward love and then reads the scriptural story around Christ. This is his explicit use of 1 Timothy 1:5.
