Must we confess before receiving Communion because God cannot be in the presence of sin?

Full Question

It is my understanding that we should be cleansed of our sins before we receive the Eucharist because God cannot be in the presence of sin. What happens to the presence of Christ in the Eucharist if someone receives but has not repented or has not gone to confession? Does Christ cease to be present? If he remains present, what happens?


Who says God cannot be in the presence of sin? One need only read Scripture to find Jesus in the presence of sin. Perhaps you’re confusing this notion with “nothing unclean shall enter [heaven]” (Rev. 21:27).

Receiving Christ in the Eucharist forgives venial sins. The Catechism of the Catholic Church explains, “As bodily nourishment restores lost strength, so the Eucharist strengthens our charity, which tends to be weakened in daily life; and this living charity wipes away venial sins” (CCC 1394).

However, the reception of the Eucharist does not forgive mortal sins, so a person who is conscious of mortal sin must go to confession before receiving communion. The Code of Canon Law states,

A person who is conscious of grave sin is not to . . . receive the body of the Lord without previous sacramental confession unless there is a grave reason and there is no opportunity to confess; in this case the person is to remember the obligation to make an act of perfect contrition which includes the resolution of confessing as soon as possible. (CIC 916)

When a person conscious of mortal sin receives the Eucharist without prior forgiveness he commits another mortal sin and only compounds his desperate situation. Paul tells us, “Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord” (1 Cor. 11:27). The Church calls this sacrilege:

Sacrilege consists in profaning or treating unworthily the sacraments and other liturgical actions, as well as persons, things, or places consecrated to God. Sacrilege is a grave sin especially when committed against the Eucharist, for in this sacrament the true Body of Christ is made substantially present for us. (CCC 2120)

    I think what this person meant, perhaps, is that God and sin are incompatible, in which case I agree one hundred per cent. – If ANYONE of us loves God -as we should- would we invite Him -indeed, FORCE Him- to come into a festering rat infested dungeon?… Would anyone do that on purpose to someone they love?… Of course, for God NOTHING is impossible; of course, He is LOVE, and consequently patience and mercy personified: but if anyone of us is ever tempted to… ‘Play with’ or ‘abuse’ this amazing radiance beyond our comprehension I would strongly recommend that, having sincerely implored God’s favour to open their minds so they can understand, they go and read in the Bible…
