St. Augustine's 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.
 
Amen.
