For Purity

Saint Joseph, father and guardian of virgins, to whose faithful keeping Christ Jesus, innocence itself, and Mary, the virgin of virgins was entrusted, I pray and beseech you by that twofold and most precious charge, by Jesus and Mary, to save me from all uncleanness, to keep my mind untainted, my heart pure, and my body chaste; and to help me always to serve Jesus and Mary in perfect chastity. Amen.
