Other Fasting Seasons & Days
The Apostles’ Fast (Monday after All Saints Sunday - Feast of Sts. Peter & Paul 29 June)
The Typikon prescribes strict abstinence on Mondays, Wednesday, and Fridays, with wine and oil allowed on other days.
The Apostles’ Fast was first established at the First Council of Nicea in AD 325 and is observed from the Monday after All Saints day through the Feast of Sts. Peter & Paul.
We fast as usual on Mondays, Wednesdays, and Fridays. On Tuesdays, Thursdays, Sautrdays, and Sundays, however, we are allowed fish, wine, and oil.
Tradition tells us that after the Apostles were filled with the Holy Spirit at Pentecost, they began to fast in order to prepare themselves to go forth and preach the Gospel to the world. There is a verse in scripture which is said to have foretold of the Apostles’ Fast: “Can you make the guests of the Bridegroom fast while He is with them? But the time will come when the bridegroom will be taken from them; then they will fast.” (Lk 5:35)
