O my God, I am heartily sorry for having offended Thee, and I detest of all my sins because I dread the loss of Heaven and the pains of Hell, but most of all because I have offended Thee, my God, who art all good and deserving of all my love.
And I firmly resolve with the help of Thy grace to confess my sins, to do penance and to amend my life. Amen.
“. . . but most of all because I have offended Thee, my God, who art all good and deserving of all my love.”
A most vital concept in a most important prayer.

A good prayer to pray before receiving the Eucharist – as we were taught by the nuns.
Several years ago I went to Confession in a large church in San Francisco. At the end there was a long pause and I said, “Father aren’t you going to ask me to recite the Act of Contrition.?” He said, ” Why? I asked you at the beginning, Are you sorry for your sins and you said, Yes”. Just not the same.
