From the Menaion - 23 January

Synaxarion

On 23 January, we commemorate the holy hieromartyr Clement, Bishop of Ancyra, and the holy martyr Agathangel.

The blood of Agathangel and Clement slaked the thirst of the bloody sword. On the twenty-third, these martyrs, handed over to the torturers, made up what was lacking in the Passion of Christ.

By the payers of Your saints, O Christ our God, have mercy on us and save us. Amen.
