Christian feast day: Mo Chutu of Lismore (Roman Catholic Church)

Mo Chutu mac Fínaill, also known as Mochuda, Carthach or Carthach the Younger, was abbot of Rahan, County Offaly, and subsequently, founder and first abbot of Lismore, County Waterford. The saint's Life has come down in several Irish and Latin recensions, which appear to derive from a Latin original written in the 11th or 12th century.

The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with 1.27 to 1.41 billion baptized Catholics worldwide as of 2025. It is among the world's oldest and largest international institutions and has played a prominent role in the history and development of Western civilization. The Church consists of 24 sui iuris (autonomous) churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies around the world, each overseen by one or more bishops. The pope, who is the bishop of Rome, is the chief pastor of the church.
