Friday fast

[10] In the Eastern Orthodox Church, in addition to fasting from food until sundown, the faithful are enjoined to abstain from sexual relations on Fridays as well.

[11][3] According to Nikodemos the Hagiorite, Orthodox Christians are required to fast on Wednesdays and Fridays, which to eat but once a day, in the afternoon, without consuming oil or wine.

[12] Abstinence on all Fridays outside of Lent is still the preferred practice among many Catholics, who choose to maintain this tradition rather than substituting an alternative penance.

All persons who have completed their fourteenth year are bound by the law of abstinence on all Fridays unless the Friday is a solemnity, and again on Ash Wednesday; but in practice, this requirement has been greatly reduced by the Episcopal Conferences because under Canon 1253, it is these Conferences that have the authority to set down the local norms for fasting and abstinence in their territories.

[17] The 1928 Book of Common Prayer of the Protestant Episcopal Church in the United States of America describes "All the Fridays in the Year, except Christmas Day and the Epiphany, or any Friday which may intervene between these Feasts" as days "on which the church requires such a measure of abstinence as is more especially suited to extraordinary acts and exercises of devotion".

[4] The General Rules written by the founder of Methodism, John Wesley, state: "It is expected of all who desire to continue in these societies that they should continue to evidence their desire of salvation, by attending upon all the ordinances of God, such are: the public worship of God; the ministry of the Word, either read or expounded; the Supper of the Lord; family and private prayer; searching the Scriptures; and fasting or abstinence.
