Mark, Bishop of Arethusa
Saint Mark was Bishop of Arethusa in Syria. In the days of Saint Constantine the Great, Saint Mark, moved with divine zeal, destroyed a temple of the idols and raised up a church in its stead. When Julian the Apostate reigned, in 361, as the pagans were now able to avenge the destruction of their temple, Saint Mark, giving way to wrath, hid himself; but when he saw that others were being taken on his account, he gave himself up. Having no regard to his old age, they stripped him and beat his whole body, cast him into filthy sewers, and pulling him out, had children prick him with their iron writing-pens. Then they put him into a basket, smeared him with honey and a kind of relish of pickled fish, and hung him up under the burning sun to be devoured by bees and wasps. But because he bore this so nobly, his enemies repented, and unloosed him.

Since they had slain through their abstinence and struggles the fiery ragings and fierce motions of the passions, the staunch Martyrs of Christ God laid hold on the graces to drive off the pains and illnesses of the sick and work wonders both while living and after death. Strange indeed is the miracle! That these bare bones should pour forth such overflowing streams of cures. Glory be to our only God.
