Prayer of St. Thomas Aquinas for Chastity

Traditional version

Dearest Jesus! I know well that every perfect gift, and above all others that of chastity, depends upon the most powerful assistance of Thy Providence, and that without Thee a creature can do nothing. Therefore, I pray Thee to defend, with Thy grace, 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, do Thou, Who art the Supreme Lord of all my powers, take it from me, that I may with an immaculate heart advance in Thy love and service, offering myself chaste all the days of my life on the most pure altar of Thy Divinity. Amen.

Modified version

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 You to defend, with Your grace,
chastity and purity in my soul as well as in my body.

Because I have received through my senses
many impressions that have stained my chastity and purity,
do You, Who are the Supreme Lord of all my powers,
take them from me,
that I may with an immaculate 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.

Slightly Updated Plural Version

Dearest Jesus, we 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 we can do nothing.

Therefore, we pray You to defend, with Your grace,
chastity and purity in our souls as well as in our bodies.

Supreme Lord of all powers,
please take from us
all the impressions we have received through our senses
that would stain our chastity and purity,
so that we may with an immaculate heart
advance in Your love and service,
offering ourselves chastely
all the days of our lives
on the most pure altar of Your Divinity.

Amen.
