Prayer for Purity.

O Guardian of Virgins and holy Father St. Joseph, into whose faithful keeping were entrusted Christ Jesus, Innocence itself, and Mary, Virgin of virgins, I pray and beseech thee by these dear pledges, Jesus and Mary, that, being preserved from all uncleanness, I may with spotless mind, pure heart and chaste body ever serve Jesus and Mary most chastely all the days of my life.

Amen.
