Confession and Martyrdom
According to the Synaxarion, Marinus witnessed pagans offering sacrifices to their false gods. Acting on his faith, he destroyed the altar and trampled upon the idols, confessing aloud that he was a Christian.
He was arrested and subjected to severe tortures: he was beaten with whips, suspended while his sides were raked, struck with stones that knocked out his teeth, and dragged along the ground by his hair. He was then bound and brought before the archon (the local magistrate), who, after inflicting still further tortures, ordered him to be beheaded with a sword.
