St. Demetrius of Rostov
Thy Martyr Varus, O Lord, in his courageous contest for Thee received the prize of the crowns of incorruption and life from Thee, our immortal God. For since he possessed Thy strength, he cast down the tyrants and wholly destroyed the demons' strengthless presumption. O Christ God, by his prayers, save our souls, since Thou art merciful.
Kontakion in the Third Tone
Since thou hadst put on thyself thy Master's Cross as a breastplate, thou didst blunt and bring to nought the tyrants' wicked devices. Thou didst bear most savage tortures upon thy body; valiantly didst thou then finish thy godly contest. Hence from God, O noble Varus, thou wast adorned in a crown august and divine.
Kontakion in the Fourth Tone
Following Christ, O Martyr Varus, you drank of His chalice; you received the crown of martyrdom and now rejoice with the angels. Pray for our souls unceasingly.
