Orthodox Christians fast on Wednesdays and Fridays to mark two pivotal moments in the story of Jesus: his betrayal by Judas, which tradition places on a Wednesday, and his crucifixion and death on a Friday. This practice dates to the earliest years of Christianity. The Didache, a first-century manual for Christian communities, already instructs believers to fast on these two days, distinguishing them from Jewish fasting traditions that observed Mondays and Thursdays.
The practice is not optional in the traditional sense. The 69th Apostolic Canon states that any bishop, priest, deacon, or reader who does not fast on Wednesdays and Fridays should be deposed from their role, and laypeople who skip the fast should be excommunicated. While enforcement varies widely today, this gives a sense of how seriously the early Church treated these weekly fasts.
Why Wednesday and Why Friday
Wednesday commemorates the moment Judas Iscariot went to the Sanhedrin and agreed to hand Jesus over in exchange for money. In liturgical tradition, this day is sometimes called “Spy Wednesday” because it marks the beginning of Judas’s role as a secret agent working against Jesus from within the group of disciples. By fasting on Wednesdays throughout the year, Orthodox Christians keep this act of betrayal in their awareness as a reminder of the cost of turning away from God.
Friday needs less explanation for most Christians: it is the day of the crucifixion. The weekly Friday fast mirrors the solemnity of Good Friday in miniature, turning every week into a small cycle of mourning and renewal. Together, the two days frame the Passion narrative, from betrayal to death, and weave it into the rhythm of ordinary life.
More Than Skipping Meals
In Orthodox theology, fasting is never just about food. It belongs to a threefold discipline alongside prayer and almsgiving that dates back to the Apostolic Constitutions and the earliest Church canons. The logic is that each practice targets a different root of spiritual struggle: fasting addresses self-indulgence, almsgiving addresses greed and hard-heartedness, and prayer addresses pride and forgetfulness of God.
St. Peter Chrysologus, a fifth-century bishop, put it bluntly: “Fasting bears no fruit unless watered by mercy. Fasting dries up when mercy dries up.” The practical expectation is that the money saved by eating simpler meals gets redirected to people in need. Many parishes organize food drives and charitable projects during major fasting seasons, and the same principle applies on a smaller scale to the weekly Wednesday and Friday fasts. Giving up rich food without growing in generosity or attention to prayer is considered to miss the point entirely.
What the Fast Looks Like in Practice
The standard Wednesday and Friday fast means avoiding meat, dairy, eggs, and fish. In stricter observance, wine, olive oil, and hard liquor are also excluded for the full 24-hour period. Whether that period runs from midnight to midnight or from 6 p.m. the evening before to 6 p.m. on the day itself depends on local tradition. In the Orthodox Church, the liturgical day technically begins at sunset, following the Genesis pattern: “And there was evening and there was morning, one day.”
During Great Lent, the restrictions tighten further, and even vertebrate fish is excluded on Wednesdays and Fridays. Outside of Lent, the typical Wednesday/Friday fast is less severe than a Lenten fast but still eliminates all animal products for most of the faithful.
When the Fast Is Relaxed or Lifted
Not every Wednesday and Friday carries the same restrictions. Several weeks throughout the year are designated “fast-free,” meaning no fasting at all, even on Wednesday and Friday:
- Bright Week: the week after Pascha (Easter) through St. Thomas Sunday
- Trinity Week: the week after Pentecost
- The Afterfeast of Nativity to Theophany Eve: December 25 through January 4
- The week following the Sunday of the Publican and Pharisee: a preparation week before Lent when meat and all animal products are permitted every day
Certain major feast days also relax the fast when they fall on a Wednesday or Friday. The Annunciation (March 25), Palm Sunday, the Transfiguration (August 6), and the Entry of the Theotokos into the Temple (November 21) all permit fish, wine, and olive oil even though they may land on a fasting day.
Exceptions for Health and Age
Orthodox tradition recognizes that not everyone can fast in the same way. Church doctrine generally exempts children under seven from fasting. In practice, children between ages seven and ten are gradually introduced to the discipline, often starting with simplified versions of the fast. Infants and toddlers are never expected to fast.
The sick, the elderly, and those with serious health conditions have always been understood to fall under “economy,” a principle in Orthodox canon law that allows pastoral flexibility when strict observance would cause harm. The 69th Apostolic Canon itself includes an exception for anyone “hindered by some bodily infirmity.” Pregnant and lactating women occupy a more complex space. In 2016, the Ethiopian Orthodox Tewahedo Church, in collaboration with USAID, developed a nutrition guide endorsed by the patriarch that encourages pregnant and lactating women and children under seven to eat nutritious foods, including animal-source foods, during official fasting periods. The broader Orthodox world generally advises these women to discuss their fast with a priest and adjust it according to medical need.
The overarching principle is that fasting is meant to be spiritually beneficial, not physically destructive. A person who cannot fast from food is typically encouraged to fast in other ways: from entertainment, from gossip, from excess spending. The discipline adapts to the person, guided by a priest or spiritual director.
A Weekly Rhythm, Not Just a Rule
For practicing Orthodox Christians, Wednesday and Friday fasting creates a weekly structure that mirrors the great fasting seasons of the year in compressed form. Each week contains its own small Lent (Wednesday and Friday) and its own small Pascha (Sunday). This rhythm means the story of Christ’s betrayal, death, and resurrection is not something remembered only once a year during Holy Week. It shapes every seven days, turning the calendar itself into a form of prayer.
