Penitential Prayer of St. Augustine

O Lord,
The house of my soul is narrow;
enlarge it that you may enter in.
It is ruinous, O repair it!
It displeases Your sight.
I confess it, I know.
But who shall cleanse it,
to whom shall I cry but to you?
Cleanse me from my secret faults, O Lord,
and spare Your servant from strange sins.
St. Augustine of Hippo (AD 354-430)
