Idus of Leinster was a fifth-century Irish saint who played a role in the early Christianization of Ireland. As a follower of Saint Patrick, he received baptism from the apostle himself. Following his conversion, he contributed to the widespread spread of the faith across the island. Patrick eventually appointed him to serve as the bishop of Alt-Fadha, located in the region of Leinster.
Life and ministry
During the period of the Great Evangelization, Idus worked alongside other early missionaries to establish the Christian faith in Ireland. After being baptized by Saint Patrick, he was entrusted with ecclesiastical leadership. He held the position of bishop in Alt-Fadha, a settlement within the province of Leinster, where he carried out his religious duties.
Veneration
The Catholic tradition commemorates this saint annually. His feast day is observed on July 14. He is remembered primarily for his service as a bishop and his connection to the mission led by Saint Patrick.
