Christian feast day: Pope Agatho (Roman Catholic)

Pope Agatho served as the bishop of Rome from 27 June 678 until his death on 10 January 681. He heard the appeal of Wilfrid of York, who had been displaced from his see by the division of the archdiocese ordered by Theodore of Canterbury. During Agatho's tenure, the Sixth Ecumenical Council was convened to deal with monothelitism. He is venerated as a saint by both the Catholic and Eastern Orthodox churches. He is said to have been the longest lived pope ever.

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.
