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)
