St Peter of Alexandria, Bishop and Martyr
Statuit ei Dominus testamentum pacis, et principem fecit eum: ut sit illi sacerdotii dignitas in aeternum. * Memento Domine David et omnis mansuetudinis ejus.
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.
(Ecclus. 45:30 and Psalm 131:1. From the Introit at 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 Peter Thy martyr and bishop may protect us.
