St Simeon, Bishop and Martyr
The Lord made to him a covenant of peace, and made him a prince: that the dignity of the priesthood should be to him for ever. * O Lord, remember David: and all his meekness.
(Ecclesiasticus 45:30 and Psalm 131:1 from the Introit of Mass)
Be mindful of our weakness, O almighty God, and since the burden of our deeds is grievous to us, grant that the glorious intercession of blessed Simeon Thy martyr and bishop may protect us.
