Select a version approved by your parish, choosing either the traditional formula beginning with O my God I am heartily sorry or a contemporary text centered on love and sorrow for sin. Set font size between 12 and 14 pt for full-page sheets, or reduce layout to 3.5 x 2 inches for a wallet card printed on 200 gsm cardstock to prevent tearing.

Read through the text several times before entering the confessional, pausing at lines that mention firm purpose of amendment, so spoken prayer reflects understanding rather than memorized repetition.
How to Choose Between Traditional and Modern Act of Contrition Text Versions

Select the traditional formula if your parish catechism materials or priest instruct penitents to use the wording that includes references to fearing punishment and firmly resolving to amend one’s life.
Choose the contemporary version if your parish bulletin or reconciliation guide provides a text centered more explicitly on love of God and sorrow for sin because it offends divine goodness. Compare both line by line, noting differences in phrases such as “I detest all my sins” versus wording that stresses heartfelt repentance and trust in mercy. Confirm with your confessor which wording is customary in your community, especially for first reconciliation classes, so memorization aligns with local practice and avoids confusion during the sacrament.
