Saint Augustine (354-430) created this poetic prayer to the Holy Spirit: Breathe in me, O Holy Spirit, That my thoughts may all be holy. Act in me, O Holy Spirit, That my work, too, may be holy. Draw my heart, O Holy Spirit, That I love but what is holy. Strengthen me, O Holy Spirit, To defend all that is holy. Guard me, then, O Holy Spirit, That I always may be holy.
