Did you know: You are obliged to confess only mortal sins, but confessing all sins is recommended. If you are in doubt about whether a sin is mortal or venial, mention your doubt to the confessor. Remember also, confession of venial sins is very helpful for avoiding sin and advancing toward Heaven.
"Bless me Father for I have sinned. It has been (state how long) since my last confession."
"My God, I am sorry for my sins with all my heart. In choosing to do wrong and failing to do good, I have sinned against you whom I should love above all things. I firmly intend, with your help, to do penance, to sin no more, and to avoid whatever leads me to sin. Our Savior Jesus Christ suffered and died for us. In his name, my God, have mercy."
