Deus, qui beátum Petrum Cœlestínum ad summi pontificátus ápicem sublimásti, quique illum humilitáti postpónere docuísti: concéde propítius; ut ejus exémplo cuncta mundi despícere, et ad promíssa humílibus præmia perveníre felíciter mereámur.
O God, Who raised blessed Peter Celestine to the lofty dignity of Supreme Pontiff and taught him to prefer self-abasement instead; mercifully grant that by his example we may look upon all worldly things as naught, and may be worthy to reap in joy the rewards promised to the humble.
