O God, our refuge and our strength, look down with mercy upon the people who cry to Thee; and by the intercession of the glorious and immaculate Virgin Mary, Mother of God, of Saint Joseph her spouse, of the blessed Apostles Peter and Paul, and of all the saints, in Thy mercy and goodness hear our prayers for the conversion of sinners, and for the liberty and exaltation of the Holy Mother the Church. Through the same Christ Our Lord. Amen. (From Sancta Missa)
