Deus, qui ad tuéndam cathólicam fidem beátum Petrum Confessórem tuum virtúte et doctrína roborásti: concéde propítius; ut ejus exémplis et mónitis errántes ad salútem resipíscant, et fidéles in veritátis confessióne persevérent. r. Per Dóminum nostrum Jesum Christum, Fílium tuum: qui tecum vivit et regnat in unitáte Spíritus Sancti Deus, per ómnia sǽcula sæculórum. R. Amen.
