Christian feast day: Dispersion of the Apostles (formerly by the Catholic Church)

The Christian Gospels of Mark and Matthew say that, after the Ascension of Jesus, his Apostles "went out and preached everywhere". This is described in Mark 16 verses 19 and 20, and Matthew 28 verses 19 and 20. According to a tradition mentioned by Eusebius, they dispersed to distinct parts of the world. In the Middle Ages, a liturgical feast of the Dispersion of the Apostles was celebrated to commemorate their missionary work and their founding the apostolic sees. This annual feast was held on 15 July and ranked as a major double.

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.
