Yesterday, the Eastern Rites of the Church began the observance of the Dormition Fast. What is the Dormition Fast? What is a Latin Rite Catholic to think of this custom?
Referred to as either the Dormition Fast – since the Assumption of Our Lady is known as the Dormition by Eastern Catholics – or as the Assumption Fast, this is a two-week-long fasting period lasting from August 1st until Assumption Day. Father R. Janin writes that this fast is “a difficult Lent permitting only olives and vegetables cooked in water; oil is tolerated on Saturdays and Sundays.” Like the Apostles’ Fast, the Assumption Fast stretches back to the time of St. Leo the Great.
While the Assumption Fast would also fade from practice in the West, the Vigil of the Assumption on August 14th would remain a mandatory day of fasting and abstinence until 1957. Its observance as a fast day is ancient as the Catholic Encyclopedia states: "Pope Nicholas I (d. 867), in his answer to the Bulgarians, speaks of the fast on the eves of Christmas and of the Assumption...The Synod of Seligenstadt in 1022 AD mentions vigils on the eves of Christmas, Epiphany, the feast of the Apostles, the Assumption of Mary, St. Laurence, and All Saints, besides the fast of two weeks before the Nativity of St. John."
One further interesting remnant of the Assumption Fast in the West is found in Sicily where the faithful would abstain from fruit for two weeks prior to the Assumption. Assumption Day is known for its blessing of herbs and fruits so the faithful, after two weeks of such abstinence, would joyfully bring their herbs and fruits to the parish for the blessing on August 15th and then, after the blessing, give each other fruit baskets.
During greater times of Latinization in the Eastern Rites in the past few centuries, the Apostles’ Fast and the Dormition Fast were minimized to such an extent that they were not emphasized and not considered obligatory. About 20 years ago, the Dormition Fast was officially recognized as an important part of the Byzantine Catholic tradition but not as a fast of obligation. It was recommended that Byzantine Catholics voluntarily add Wednesday, and even Monday, as days of abstinence in addition to Friday abstinence during this period.
As a result, the Dormition Fast is a period of preparation for the celebration of the Assumption of Our Blessed Lady into Heaven on August 15th. It is wise for us - even Latin Rite Catholics - to adopt this time as a time of prayer and preparation. While we are not canonically bound under the pain of sin to observe this period of fasting, it is certainly wise for us to fast willingly at this time in order to prepare for the Assumption better. And moreover, offering our fasting and added sacrifices for the intentions of our Lady would be a most salutary effort indeed.
