Saint Aloysius, adorned with angelic virtues, I, thy most
unworthy client, commend to thee most earnestly the chastity
of my mind and body. I beseech thee, for the sake of thine
angelic purity, to commend me to the Immaculate Lamb,
Christ Jesus, and to His most holy Mother, the Virgin of
virgins; and to protect me from every grievous sin. Permit me
not to defile myself by any spot of impurity; nay, when thou
seest me in temptation or in the danger of sin, banish far from
my heart every unclean thought and desire. Awaken in me the
thought of eternity and of Jesus crucified; imprint deeply in
my heart a lively sense of the holy fear of God; set me on fire
with the love of God; grant me the grace to imitate thee on
earth that I may worthily enjoy the possession of God in
heaven with thee. Amen.

Our Father, Hail Mary, Glory be.
V. Pray for us, Saint Aloysius,
R. That we may be made worthy of the promises of Christ.

Let us Pray.
O God, the Giver of all heavenly gifts, who in the angelic
youth, Aloysius, didst join wondrous innocence with equal
penance: be entreated by his merits and his prayers, and grant
unto us who have not followed him in his innocence the grace
to imitate him in his penance. Through Christ our Lord.
Amen.
