A prayer recited by the penitent during the Roman Catholic sacrament of Confession.

 "O my God, I am heartily sorry 
   for having offended Thee,
   and I detest all my sins,
   because I dread the loss of Heaven 
   and the pains of Hell,
   but most of all because I 
   offend Thee, my God,
   Who art all-good and deserving 
   of all my love.
   I firmly resolve, with the help 
   of Thy grace to confess my sins,
   to do penance 
   and to amend my life. Amen."

 "O My Lord, I am heartily sorry for all my sins, 
   help me to live like Jesus and not sin again. 
                        Amen"

  Version in use in Ireland, 1960s: 
  "O my God, I am heartily sorry
  for having offended Thee
  and I detest my sins
  above every other evil
  because they displease Thee, my God,
  Who, in Thy infinite wisdom,
  art so deserving of all my love
  and I firmly resolve 
  with the help of Thy grace
  never more to offend Thee
  and to amend my life. Amen."
