17 July (Byzantine Christianity) Epip 23 (Coptic Orthodox Church of Alexandria) (Martyrdom) Margaret, known as Margaret of Antioch in the West, and as Saint Marina the Great Martyr (Ancient Greek: Ἁγία Μαρίνα) in the East, is celebrated as a saint on 20 July in Western Christianity, on 30th of July (Julian calendar) by the Eastern Orthodox Church, and on Epip 23 and Hathor 23 in the Coptic Orthodox Church.
She was reputed to have promised very powerful indulgences to those who wrote or read her life or invoked her intercessions; these no doubt helped the spread of her following.
Her mother having died soon after her birth, Margaret was nursed by a Christian woman five or six leagues (15 to 18 miles (24 to 29 km)) from Antioch.
Having embraced Christianity and consecrated her virginity to God, Margaret was disowned by her father, adopted by her nurse, and lived in the country keeping sheep with her foster mother.
[13] The Eastern Orthodox Church knows Margaret as Saint Marina, and celebrates her feast day on 30 July.
In 2022, Margaret was officially added to the Episcopal Church liturgical calendar with a feast day she shares with Catherine of Alexandria and Barbara of Nicomedia on 24 November.
