Saint Acacius the Confessor lived during the Decian persecution, and was Bishop of Melitene, Armenia.
Arrested as a Christian, Saint Acacius was brought before the governor Marcianus, who ordered that he be tortured. He was not put to death, but was set free after a while, bearing the wounds of Christ on his body. He died in peace.
Saint Acacius the Confessor is also commemorated on March 31. He should not be confused with another Saint Acacius of Melitene (April 17) who lived in the fifth century.
