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. Amen


Penitential Prayer of St. Ambrose of Milan

O Lord, who hast mercy upon all,take away from me my sins,
and mercifully kindle in methe fire of thy Holy Spirit.
Take away from me the heart of stone,and give me a heart of flesh,
a heart to love and adore Thee,a heart to delight in Thee,
to follow and enjoy Thee, for Christ's sake, Amen
