Romae natalis sancti Pii Quinti, ex Ordine Praedicatorum, Papae et Confessoris; qui, ecclesiasticae disciplinae restituendae, haeresibus exstirpandis et Christiani nominis hostibus conterendis strenue ac feliciter incumbens, vitae ac legum sanctitate catholicam Ecclesiam gubernavit. Ipsius autem festivitas tertio Nonas mensis hujus celebratur.
