Prayer for Chastity by St. Thomas Aquinas
Dearest Jesus! I know well that every perfect gift,
and above all others that of chastity, depends upon the most
powerful assistance of Your providence, and that without You
a creature can do nothing. Therefore, I pray that You defend, with Your grace, the gift of chastity and purity in my soul as well as in my body.
And if I have ever received through my senses any impression
that could stain my chastity and purity, I ask You, who are the Supreme Lord of all my powers, to take it from me, so that I may with a clean heart advance in Your love and service, offering myself chaste all the days of my life on the most pure altar of Your divinity. Amen.
