Jonah's Fast, also known as the Fast of the People of Nineveh
"I cried out to the Lord because of my affliction, And He answered me. “Out of the belly of Sheol I cried, And You heard my voice."
The Coptic Orthodox Church fasts in commemoration of the fast of the Prophet Jonah in the belly of the fish and of the People of Nineveh for 3 days starting on Monday, January 29, 2018 - Wednesday, January 31, 2018 with the prayers of the Divine Liturgy at 9:00 AM. The church celebrates the Feast of Jonah on February 1, 2018. with the prayer of the Divine Liturgy at 8:00 AM.
The Prophet Jonah's endurance and prayer in the belly of the big fish became a pattern for Christian asceticism, which was realized, for instance, in the life of Basil the Great (Saint Gregory of Nazianzus)
Saint Mary Coptic Orthodox Church wishes you a blessed Fast and Feast of Jonah.
