Holy apostle Philologus of the Seventy;
Entreat the merciful;
To grant our souls forgiveness of transgressions.Kontakion (Tone 4)[2]
The Church ever sees you as a shining star, O apostle Philologus,
Your miracles have manifested great enlightenment.
Therefore we cry out to Christ:
"Save those who with faith honor Your apostle, O Most Merciful One."
