Today, on August 6th, we celebrate the Feast of the Transfiguration. +++The feast has been celebrated since the 7th century.+++In 1457, Pope Calixtus III set the date on August 6th as a thank offering for the victory over the Turks at Belgrade on that day in 1456.+++In 2002, Pope John Paul II updated the meditations of the rosary with five “luminous mysteries,” of which the Transfiguration is one.
