The Holy Martyr Mertius was a soldier. He suffered for Christ in Africa during the reign of Diocletian (284-305). The emperor demanded that he offer sacrifice to idols, and when he refused, gave him over to torture. The saint suffered fierce torments, not making a sound. He was thrown into prison, where he died from hunger and his wounds.
Troparion — Tone 4
Your holy martyr Mertius, O Lord, / Through his sufferings has received an incorruptible crown from You, our God. / For having Your strength, he laid low his adversaries, / And shattered the powerless boldness of demons. / Through his intercessions, save our souls!
