Beheading of John the Baptist
Great Feast, Αποτομή Κεφαλής Ιωάννου
The Church commemorates on August 29 the martyric death of St. John the Forerunner. Imprisoned by Herod Antipas for rebuking his unlawful union with Herodias, John was beheaded at the request of Herodias, made through her daughter, whose dancing had pleased Herod at his birthday feast. Thus the greatest of the prophets sealed his preaching of repentance with his blood.
