Act of Contrition
Traditional · Catholic prayer
1O my God, I am heartily sorry for having offended Thee,
2and I detest all my sins because of thy just punishments,
3but most of all because they offend Thee, my God,
4who art all good and deserving of all my love.
5I firmly resolve with the help of Thy grace
6to sin no more and to avoid the near occasions of sin. Amen.
