Feast of the Transfiguration

The Feast of the Transfiguration of Jesus is celebrated by various Christian communities. The origins of the feast are less than certain and may have derived from the dedication of three basilicas on Mount Tabor. The feast was present in various forms by the 9th century, and in the Western Church was made a universal feast on 6 August by Pope Callixtus III to commemorate the raising of the Siege of Belgrade (1456).

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.

In some liturgical calendars (e.g. the Lutheran and United Methodist) the last Sunday in the Epiphany season (that immediately preceding Ash Wednesday) is also devoted to this event. In the Church of Sweden and the Church of Finland, however, the Feast is celebrated on the seventh Sunday after Trinity, the eighth Sunday after Pentecost.
