Christian feast day: Pelagia (Eastern Orthodox and Roman Catholic Churches)

Pelagia, distinguished as Pelagia of Antioch, Pelagia the Penitent, and Pelagia the Harlot, was a Christian saint and hermit in the 4th or 5th century. Her feast day was celebrated on 8 October, originally in common with Saints Pelagia the Virgin and Pelagia of Tarsus. Pelagia died as a result of extreme asceticism, which had emaciated her to the point she could no longer be recognized. According to Orthodox tradition, she was buried in her cell on the Mount of Olives. Upon the discovery that the renowned monk had been a woman, the holy fathers tried to keep it a secret, but the gossip spread and her relics drew pilgrims from as far off as Jericho and the Jordan valley.

The Eastern Orthodox Church, officially the Orthodox Catholic Church, and also called the Greek Orthodox Church or simply the Orthodox Church, is one of the three major doctrinal and jurisdictional groups of Christianity, with approximately 230 million baptised members. It operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the pope of the Catholic Church. Nevertheless, the Ecumenical Patriarch of Constantinople is recognised by them as primus inter pares, a title held by the patriarch of Rome prior to 1054. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played an especially prominent role in the history and culture of Eastern and Southeastern Europe. Since 2018, there has been an ongoing schism between Constantinople and Moscow, with the two not in full communion with each other.

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.
