Saint Joseph, father and guardian of virgins, into whose faithful keeping were entrusted Innocence itself, Christ Jesus, and Mary, the Virgin of virgins, I pray and beseech you through Jesus and Mary, those pledges so dear to you, to keep me from all uncleanness, and to grant that my mind may be untainted, my heart pure, and my body chaste. Help me always to serve Jesus and Mary in perfect chastity. Amen.
