Feastday: January 8
Priest martyr of Caesarea in Cappadocia. He suffered in the persecution conducted by Emperor Diocletian.
Saint Carterius lived during the reign of Diocletian, and was a teacher in Caesarea of Cappadocia. He stood before a statue of Serapis and prayed to Christ, and the idol shattered to pieces. The procurator Urbanus ordered St Carterius to be tortured and then beheaded. Some, however, say he was killed with a spear.
