The Eastern Orthodox Church venerates Saint Christopher on 9 May. The Tridentine Calendar allowed a commemoration of Saint Christopher on 25 July only in private Masses. This restriction was lifted later (see General Roman Calendar as in 1954). While the Roman Catholic Church still approves devotion to him listing him in the Roman Martyrology among the saints venerated on 25 July it removed his feast day from the Roman Catholic calendar of saints in 1969. At that time the church declared that this commemoration was not of Roman tradition in view of the relatively late date (about 1550) and limited manner in which it was accepted into the Roman calendar.
