The Prayer of Saint Mardarios

Sovereign God, the Father Almighty, O Lord, the Onlybegotten  Son, Jesus Christ,
and Thou, O Holy Spirit, one Godhead, one Power, have mercy on me, a sinner;
and by the judgments which Thou knowest save me, Thine unworthy servant; for
blessed art Thou unto the ages of ages. Amen.
