Saint Malachy, archbishop of Armagh, born in Armagh about 1095, died at C'lairvaux, France, Nov. 2, 1148. He was of noble birth, became a monk, and was appointed vicar of St. Celsus, archbishop of Armagh, who destined him for his successor. He studied canon law under St. Malchus, bishop of Lismore, and rebuilt a portion of the monastery of Ben-chor. About 1127 he was appointed bishop of the united sees of Down and Connor, He visited on foot every hamlet in both dioceses, restored reverence for the matrimonial contract, repaired churches, established schools, obtained enlightened priests, and introduced everywhere the Roman liturgy and ritual. He became archbishop in 1129; but as the temporalities of Armagh had been confiscated, he continued to govern the diocese of Connor. This city was sacked in a civil war, and with 120 disciples he retired into Munster, built the monastery of Ibrach, and as primate made a visitation of Munster and Connaught. Toward tin-end of 1134 he took possession of the see of Armagh, completed his reforms, and made a second visitation of the dioceses of Munster. In 1137 he resigned his archbishopric, consecrated a bishop for Connor, and reserved for himself the poorer and obscurer see of Down, where he founded various institutions.
In 113!> he went to Rome, to confer with the pope about a thorough renovation of the Irish church, and received full power as legate a latere. After his return he visited every part of the island, and in 1148 held a national council at Inis Padrig or Patrick's Holme; disciplinary decrees were enacted, and a petition was drawn up for the establishment of two metropolitan sees. With these Malachy started for France, hoping to inert Pope Eugenius III. at Clairvaux; but he arrived there after the pope's departure, fell ill of a fever, and died in the arms of St. Bernard, who pronounced a panegyric at his funeral, and wrote his life (translated by Maffoi). He was canonized by Clement III. in 1190, and his feast is celebrated on Nov. 3. - A "Prophecy concerning the Lives of the future Roman Pontiffs,'* beginning with Celestine II., elected in 1143, popularly attributed to St. Malachy, is now considered to have originated in the conclave of 1590. It was first published in 1595 by the Benedictine Arnould de Wyon, and is to be found in Moreri's Dictionnaire historique.
