Communion in mortal sin: can you receive without confession?

Can you receive Communion in mortal sin?

Can you receive Communion in mortal sin? The Church’s answer is clear: “Anyone conscious of a grave sin must receive the sacrament of Reconciliation before coming to communion” (CCC 1385). Canon law says the same (canon 916). To receive Christ in the Eucharist you must be in the state of grace, and mortal sin is precisely the loss of it (CCC 1415, 1861). So the order is confession first, then Communion.

The reason is not that God wants to keep you away. The Eucharist “is not ordered to the forgiveness of mortal sins”; that is the work of the Sacrament of Reconciliation (CCC 1395). Each sacrament has its gift. Communion is properly the sacrament of those already in full communion with the Church, and it strengthens their friendship with Christ; confession is the sacrament that restores that friendship when it has been broken. Going to confession first is the way back to the altar, not a barrier in front of it.

Notice what St Paul asks: that each person examine himself. No one can see into another’s conscience, and “the judgment of one’s state of grace obviously belongs only to the person involved” (Ecclesia de Eucharistia 37). So never judge the person who stays in the pew, or the one who goes up. Look only at your own heart, honestly and without fear.

Can I receive Communion without going to confession?

Yes, if you are not conscious of a mortal sin. You do not need to confess before every Communion. Venial sins, the everyday faults of impatience, distraction or unkind words, do not break your friendship with God, and the Eucharist itself “wipes away venial sins” by renewing your charity (CCC 1394). The penitential act at the start of Mass, or a quiet act of contrition, prepares your heart. The Church in fact encourages you to receive whenever you take part in Mass with the right dispositions (CCC 1388).

Confession becomes necessary before Communion when you are aware of a mortal sin. The Church also asks every Catholic to confess serious sins at least once a year (canon 989), and to receive Communion at least once a year, in the Easter season (CCC 1389). Our guides to venial sin and mortal sin explain the difference in full.

What makes a sin mortal?

A sin is mortal only when three conditions are met together (CCC 1857). If any one is missing, the sin is venial: still worth confessing, but it does not keep you from Communion (CCC 1862).

• Grave matter: the act is seriously wrong, as the Ten Commandments name it (CCC 1858).
• Full knowledge: you knew it was seriously wrong (CCC 1859).
• Deliberate consent: you freely chose it, as a real personal decision (CCC 1859).

Knowledge and freedom can be reduced. Ignorance you are not to blame for, strong passions, outside pressure and pathological disorders can lessen or even remove a person’s responsibility for a grave act (CCC 1860). This is why the Church says that while we can judge that an act is gravely wrong in itself, we “must entrust judgment of persons to the justice and mercy of God” (CCC 1861). It is also why you should neither shrug off a serious sin nor condemn yourself for every lapse.

What to do before Mass if you are not sure

Suppose you are on your way to Mass and something from the week weighs on you. Here is a calm way through it, in order.

1. 1

   Ask the honest question

   Did I do something seriously wrong, knowing it was seriously wrong, and freely choose it? Answer as you would if a friend described the same thing to you: honestly, without inflating or excusing.

2. 2

   If the answer is yes, look for confession first

   Many parishes hear confessions before Mass; check the bulletin or website, or ask in the sacristy. Priests are often glad to hear a confession before Mass begins if they have time. Our guide on what to say in confession gives you the words.

3. 3

   If you honestly cannot tell

   Confess before Mass if you can and tell the priest you are unsure. If you cannot, confessors have long counselled that a real doubt is not the same as being conscious of mortal sin: after a sincere act of contrition you may receive, and bring the question to your next confession. Confessing first is better when you can.

4. 4

   If you cannot receive, stay

   Remain at Mass: your presence, your prayer and the Sunday obligation still matter. Stay in the pew during Communion, or, where it is the custom, come forward with your arms crossed for a blessing. Make an act of contrition and a spiritual communion.

5. 5

   Make the appointment

   Find the next confession time this week, or call the parish to ask for one. Then come back to the altar with a clear and peaceful conscience.

Perfect contrition, and the “grave reason” exception

The Church allows one narrow exception. A person conscious of mortal sin may receive Communion without confessing first only when there is a grave reason to receive and there is no possibility of going to confession; both must be true. In that case the person must make an act of perfect contrition, which includes the resolve to confess as soon as possible (CCC 1457; canon 916). Without both, the Catechism is plain: contrition alone is not enough, and one should not receive “even if he experiences deep contrition” (CCC 1457).

Such cases are rare, and the Church leaves them to an honest conscience and, where possible, a priest’s advice. Feeling awkward about staying in the pew is not, by itself, a grave reason. No one is obliged to receive at every Mass; participation in the Mass “remains necessary, important, meaningful and fruitful” even when sacramental Communion is not possible (Sacramentum Caritatis 55), and many people stay seated for many reasons that no one else knows.

Perfect contrition matters far beyond this exception. When sorrow springs from love of God above all things, it “obtains forgiveness of mortal sins if it includes the firm resolution to have recourse to sacramental confession as soon as possible” (CCC 1452). So you never have to wait for confession to turn back to God: make an act of contrition tonight, and you can trust his mercy now. Then confess the sin, as you promised, and receive Communion again.

What is a spiritual communion?

A spiritual communion is a prayer of longing: when you cannot receive the Eucharist, you tell Christ that you believe he is present, that you love him and that you desire to receive him, and you ask him to come into your heart. The practice “has happily been established in the Church for centuries,” recommended by the saints (Ecclesia de Eucharistia 34), and the Church encourages it whenever sacramental Communion is not possible (Sacramentum Caritatis 55). If you are conscious of mortal sin, pray it together with an act of contrition and your resolve to confess.
