Preces pópuli tui, quǽsumus, Dómine, cleménter exáudi: ut beáti Marcélli Mártyris tui atque Pontíficis méritis adjuvémur, cujus passióne lætámur.
O Lord, we beseech You, graciously hear the prayers of Your people, that we may be helped by the merits of blessed Marcellus, Your Pope and Martyr, whose sufferings we celebrate.
