The Hieromartyrs Ephraim, Basil, Eugene, Elpidius, Agathodorus, Aetherius, and Capiton carried the Gospel of Christ into the North Black Sea region from the Danube to the Dniepr, including the Crimea. They were bishops of Cherson at different times during the fourth century, and they sealed their apostolic activity with martyrdom.Only Aetherius died in peace.
At the beginning of the fourth century a bishop’s See was established at Cherson. This was a critical period when Cherson served as a base for the Roman armies which constantly passed through the area. During the reign of Diocletian (284-305), the Patriarch of Jerusalem sent many bishops to preach the Gospel in various lands. Two of them, Ephraim and Basil, arrived in Cherson and planted the Word of God there.
Later on, St Ephraim went to the peoples living along the Danube, where he underwent many tribulations and sorrows. He was beheaded at the start of the persecution.
