Ure igne Sancti Spiritus 

Refine our hearts and affections Lord, in the fire of the Holy Spirit, so that our bodies may be chaste and our hearts clean to serve Thee according to Thy pleasure

Rex Virginum, amator castitatis

With the heavenly dew of Thy blessing, God, Kong of virgins and Lover of stainless chastity, Quench the wildfire of lust in my body, Leaving all of me , body and soul, steadfast in purity. Deaden within me the stings of desire and all lustful excitements. Give me true and abiding chastity, and therewith all those other gifts of Thine in which Thou truly delightest, enabling me to offer daily sacrifice in praise of Thee with a chaste body and clean heart.
