Saints Prochorus, Nicanor, Timon and Parmenas, Apostles of the Seventy were among the first deacons in the Church of Christ.
In the Acts of the Holy Apostles (6:1-6) it is said that the twelve Apostles chose seven men: Stephen, Philip, Prochorus, Nicanor, Timon, Parmenas and Nicholas, full of the Holy Spirit and wisdom, and appointed them to serve as deacons.
They are commemorated together on July 28, although they died at various times and in various places.
At first, St Prochorus accompanied the holy Apostle Peter, who made him bishop in the city of Nicomedia. After the Dormition of the Most Holy Theotokos, Prochorus was a companion and coworker of the holy Apostle John the Theologian and was banished with him to the island of Patmos. There he wrote down the Book of Revelation concerning the final fate of the world. Upon returning to Nicomedia, St Prochorus converted pagans to Christ in the city of Antioch, where he suffered martyrdom.
