The Holy Eucharist Can Be Dangerous to Your Soul If…

Listen to this article


When Catholics gather to celebrate Mass, the high point is receiving the Holy Eucharist. In this Sacrament, bread and wine are transformed into the Body and Blood of Jesus Christ. The Eucharist is seen as “the source and summit of the Christian life” (Catechism of the Catholic Church, 1324). However, receiving the Eucharist isn’t something to take lightly. It’s not like taking a piece of bread at dinner; it’s a deeply spiritual act with serious consequences. What many people may not know is that receiving the Eucharist can be dangerous to your soul if done in a state of mortal sin or without proper reverence and understanding.

Receiving the Eucharist in a State of Mortal Sin

What is Mortal Sin?

Mortal sin is a grave violation of God’s law that cuts us off from His grace. For a sin to be mortal, it must meet three conditions: it must be of grave matter, committed with full knowledge, and done with deliberate consent (CCC, 1857). If someone is in a state of mortal sin, they are spiritually dead, cut off from the life of grace that God wants for us.

The Biblical Foundation

St. Paul warns against receiving the Eucharist in a state of sin:

“Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord.” (1 Corinthians 11:27, ESV)

The Consequences

The Church teaches that if someone in a state of mortal sin receives the Holy Eucharist, they commit another mortal sin of sacrilege. “Sacrilege consists in profaning or treating unworthily the sacraments and other liturgical actions, as well as persons, things, or places consecrated to God” (CCC, 2120).

Receiving Without Proper Understanding

Catechesis and the Eucharist

The Church emphasizes the importance of proper catechesis (teaching of the faith) for those who partake of the Eucharist. When people don’t fully understand what the Eucharist is, there’s a danger of treating it as something less than it really is—the Body and Blood of Christ. Understanding the true meaning of the Eucharist helps us approach it with the reverence and awe it deserves.

The Need for Discernment

Before we approach the altar to receive Communion, it’s essential to discern whether we are prepared and understand what we are about to do. St. Paul also says,

“Let a person examine himself, then, and so eat of the bread and drink of the cup.” (1 Corinthians 11:28, ESV)

Receiving Without Proper Reverence

What Does Reverence Mean?

Reverence means showing deep respect and honor. When it comes to the Eucharist, this means understanding that we are not just receiving a piece of bread and a sip of wine; we are receiving Jesus Himself. The Church prescribes certain rituals and postures to help instill this sense of reverence, such as kneeling, making the sign of the cross, and responding “Amen” when presented with the sacrament.

The Problem with Casualness

A casual approach to the Eucharist can lead to what the Church calls “indifferentism,” the sin of believing that one religion is as good as another or treating matters of faith lightly (CCC, indifferentism, 2094). Treating the Eucharist casually can be dangerous because it diminishes the real presence of Christ and could lead us into sin or spiritual laziness.

What To Do If You’re Not Prepared

The Sacrament of Reconciliation

If you find yourself in a state of mortal sin, the Church urges you to go to confession before receiving the Eucharist. The Sacrament of Reconciliation restores us to a state of grace, making it safe and beneficial to receive the Holy Eucharist.

Spiritual Communion

If for some reason you can’t receive the Eucharist—whether it’s because you’re not in a state of grace, or you’re not adequately prepared, or you haven’t fasted—you can still make an act of “spiritual communion.” This is a prayerful way of uniting yourself to Jesus in the Eucharist, even when you can’t physically receive Him.


The Eucharist is the most extraordinary gift that Jesus has given to the Church. It’s a way to draw close to Him and to be strengthened in our journey of faith. However, we must approach this great sacrament with understanding, preparation, and utmost reverence. The act of receiving the Eucharist can be dangerous to our souls if we do so in a state of mortal sin, without proper understanding, or without the reverence it deserves. Therefore, it is crucial to be in a state of grace, to understand what the Eucharist truly is, and to approach it with due reverence. By doing so, we can fully partake in the richness of grace that God so generously offers us in this most Holy Sacrament.
