St. Hyginus, Pope 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.
(Ecclesiasticus 45:30 and Psalm 131:1 from the Introit of Mass)
Have regard to our weakness, O almighty God, and since the burden of our deeds is grievous to us, grant that the glorious intercession of blessed Hyginus Thy martyr and bishop may protect us.
