Transfiguration, FEAST OF THE, instituted in honour of the Transfiguration of Christ (Matt. xvii. 2), is one of the twelve great feasts which come next after Easter in dignity. In the Anglican Church it is only a Black-letter feast. It is commonly said to have been instituted in the West by Pope Calixtus III. (1455-58), but is mentioned in the 9th century. Both Greeks and Westerns keep it on the 6th August.
