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.  Amen. 

- Prayer of St. Augustine
