The holiday and feast day for the Transfiguration of Christ celebrates the revelation of Jesus’ divinity.
In the Syriac Orthodox, Indian Orthodox, Revised Julian calendars within Eastern Orthodoxy, Roman Catholic, Old Catholic, and Anglican churches, the Feast of the Transfiguration is observed on 6 August. In those Orthodox churches which continue to follow the Julian Calendar, August 6 falls on August 19 of the Gregorian Calendar. The Transfiguration is considered a major feast, numbered among the twelve Great Feasts in Orthodoxy. In all these churches, if the feast falls on a Sunday, its liturgy is not combined with the Sunday liturgy, but completely replaces it.
