Missionary work of Jesus's Apostles after his ascension
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.
