(Ceillach) (Saint) Bishop (April 6) (12th century) An Archbishop of Armagh, renowned throughout Ireland for his piety and learning. Supported by a Synod of fifty Bishops and several hundred priests, he, everywhere in the island, restored Church discipline. He died April 4, 1129, at Ard-Patrick in Munster, in the fiftieth year of his age, and was buried at Lismore. When dying he sent his pastoral staff to his disciple, Saint Malachias, then Bishop of Connor, which led to the election of that holy man to the Primatial See. Saint Bernard eulogises Saint Celsus in the life he wrote of Saint Malachy.
