Troparion — Tone 4
Your holy martyrs Elpidius, Marcellus, and Eustochius, O Lord, / through their sufferings have received incorruptible crowns from You, our God. / For having Your strength, they laid low their adversaries, / and shattered the powerless boldness of demons. / Through their intercessions, save our souls!
