Commemorated on September 1.

The Holy Martyrs Callista and her brothers Evodus and Hermogenes, with other Christians of Nicomedia, were brought to trial before the pagan governor for confessing their faith in Christ. Refusing to offer sacrifice to idols, they were cut down by the sword.

Troparion

Your holy martyrs, 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!
