Præsta, quǽsumus, omnípotens Deus: ut beáti Petri Mártyris tui fidem cóngrua devotióne sectémur; qui, pro ejúsdem fídei dilatatióne, martýrii palmam méruit obtinére.
Grant us grace, we beseech thee, O Almighty God, to follow with zeal conformable thereto after the pattern of that great example of faith, thy blessed Martyr Peter, who, for the spreading of the same faith, did so run as to obtain the palm of martyrdom.
