St. Chillen, or Killian, of Ireland, Priest
HE was a native of Ireland, and a near kinsman of St. Fiaker; and on his return from Rome, where he had been on a pilgrimage, visited that saint in his solitude of Brie, where he spent some time with him in divine meditation and heavenly conversation. He was afterwards sent by St. Faro, bishop of Meaux, to preach the gospel in Artois; which commission he executed with admirable sanctity and fruit, bringing many souls to the knowledge of Christ, and happily ended his days in the seventh century. His body is kept at Aubigny, near Arras, in a priory of canon-regulars which bears his name. He is styled a bishop in Colgans MSS. See Le Cointe, Annal. t. 3, p. 625. Mabillon, Act. SS. Ben. t. 2, p. 619.
