Martyr Dometius of Persia and his two disciples - Troparion & Kontakion
Troparion — Tone 4
Preparing yourself through prayer and fasting on the mountain, / you destroyed the hosts of spiritual enemies with the weapon of the Cross. / And then courageously preparing yourself for martyrdom, / you were crowned by God for both your life and death, / O ever-memorable venerable martyr Dometius.
Kontakion — Tone 6
Despising corruption and degrading philosophies, / O venerable martyr Dometius, / you became a great guide of monks. / You did not fear the wrath of the king, / who did not wish to honor Christ the true God. / Therefore in death You did raise the hymn: / God is with me, and no one will be against me.
