If you planned on going to confession but were not able to make it in prior to Holy Week, consider Perfect Contrition until you have the next opportunity to go. More information is provided by Fr. Richards here:
Because of COVID–19 measures in place this Lent and Holy Week of 2020, the sacrament of Reconciliation (or Confession) has only limited availability. Fr. Joe and I are still offering curbside confessions Monday and Tuesday, but normally, during this time, we have much more opportunity. For this reason, I wanted to introduce “perfect contrition” to those of you who aren’t familiar with it. If those who attend individual confession more frequently, do this now, then, perhaps, there will be more availability for those who haven’t been to confession in a long time, but are drawn to individual confession because of the season.
“perfect contrition” is sorrow for one's sins based upon love for God, which includes the firm resolution not to commit them anymore.
When contrition arises from “a love by which God is loved above all else, contrition is called ‘perfect,’” the Catechism of the Catholic Church teaches.
The catechism explains that perfect contrition “remits venial sins; it also obtains forgiveness of mortal sins if it includes the firm resolution to have recourse to sacramental confession as soon as possible.”
Imperfect contrition, also known as attrition— sorrow for one’s sins based upon fear of the punishment of Hell— is sufficient for a priest to absolve you in the confessional, but not enough to obtain the forgiveness of mortal sin without sacramental confession to a priest, the catechism explains.
So, how is an act of perfect contrition done?
Practically, there are two things a Catholic must do.
The first is to pray an act of contrition "out of love for God,"
Being sorry out of love for God has often been described as having a desire to be reunited to God because of who he is-- because of God's perfect love for us, and because of sorrow for having offended God by sin. It means wanting to live in unity with God, and to put aside the sins that stand in the way.
There is no set formula for making an act of contrition, but a common one reads as follows: “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.”
Second, a Catholic must make a firm commitment to go to confession when that becomes possible.
An act of perfect contrition is not a replacement for the sacrament of penance— far from it.
Even perfect contrition is never separated from the sacrament, at least in intention. If one makes a perfect act of contrition, it's not “Oh, I don't have to go to confession any more.” Quite the opposite.
The person who says: “I have perfect contrition, but I'm not going to the sacrament” does not in fact have perfect contrition.
The sacrament of penance remains the sole, ordinary means for the forgiveness of mortal sins after baptism. Contrition is about conversion, he said, which means turning away from attachment to sin, and turning toward the sacraments.
Pope Francis recently encouraged Catholics confined to their homes to ask God for forgiveness and then to go to confession when they are able.
“You do what the Catechism says. It is very clear: if you do not find a priest to hear your confession, speak to God, he is your father, and tell him the truth...Promise him: ‘Later I will confess, but forgive me now.’ And immediately you will return to the grace of God,” Pope Francis said.
All this being said, I also recommend an act of perfect contrition to those who struggle with habitual sin. There can be, what I call “a spiraling” effect when someone falls in a serious or grave habitual sin (or in modern psychological terms – an “addiction”). One falls, then says to themselves – “I feel terrible/ashamed/angry at myself, so I want to feel better again. This sin makes me feel good for a moment, so I may as well do it again, and again, and again, until I can finally feel better through the sacrament of reconciliation”. I tell them to let the Lord make them feel better by making an act of perfect contrition right away instead of sinning again. I call this “repenting quickly”.
I hope this has been a helpful suggestion. God bless you and have a great Holy Week! Fr. Peter Richards
