Sins to Confess before Confirmation

Sins to Confess before Confirmation

So you are all set for your confirmation but haven’t confessed yet. Have no or little idea on what to reveal inside the confession box? This post is for you! In here, we will be talking about sins to confess before confirmation.

Mortal Sins vs Venial Sins

First off, let’s define what sin is according to the Catechism.

1854 “Sins are rightly evaluated according to their gravity. The distinction between mortal and venial sin, already evident in Scripture, became part of the tradition of the Church. It is corroborated by human experience.”

It mentions the two types of sin, mortal and venial.

1855 “Mortal sin destroys charity in the heart of man by a grave violation of God’s law; it turns man away from God, who is his ultimate end and his beatitude, by preferring an inferior good to him.”

Venial sin allows charity to subsist, even though it offends and wounds it.

For a sin to be mortal, three conditions must be met:

  • Object is grave matter
  • Committed with full knowledge and
  • Deliberate consent

For example, you engaged in adultery. How to know if it is a mortal sin?

First, check if adultery is a grave matter. Ten commandments can be your basis.

“You have heard that it was said, You shall not commit adultery. But I say to you that every one who looks at a woman lustfully has already committed adultery with her in his heart.”

6th Commandment

Since it is the 6th commandment, we can now consider it as a grave sin.

Another condition is you commited it with full knowledge.

Are you aware that it is a sin? If yes, you are one criteria away to be a mortal sinner.

Last is deliberate consent. It is when you still commit a sin even though you know it’s a sin. You must intentionally do it.

So if you know that adultery is a sin yet you still did it, you committed a mortal sin.

These are your 3 conditions. If one is absent, the sin will fall as venial sin.

For example, you are practicing adultery without knowing it is actually a sin. This can diminish its gravity thus, a venial sin.

Sins to Confess

Regardless if for confirmation or not, according to the Catechism, you have to confess all the mortal sins.

1456 “Confession to a priest is an essential part of the sacrament of Penance: All mortal sins of which penitents after a diligent self-examination are conscious must be recounted by them in confession, even if they are most secret and have been committed against the last two precepts of the Decalogue; for these sins sometimes wound the soul more grievously and are more dangerous than those which are committed openly.”

As for venial sins, although not required, it is advisable to include them for confession.

1458 “Without being strictly necessary, confession of everyday faults (venial sins) is nevertheless strongly recommended by the Church. Indeed the regular confession of our venial sins helps us form our conscience, fight against evil tendencies, let ourselves be healed by Christ and progress in the life of the Spirit.”
