Sergios and Vakchos
October 7, Martyr, Σέργιος και Βάκχος
Saints Sergius and Bacchus were high-ranking officers in the Roman army at the end of the third century, secretly Christians and beloved of the emperor. When their faith was discovered they refused to sacrifice to the idols; stripped of their rank, they were paraded in mockery and cruelly tortured. Bacchus died under the blows, and Sergius was afterward beheaded in Syria.
