The miracle of God’s physical presence to us at every Mass is the truest testament to Christ’s love for us and His desire for each of us to have a personal relationship with Him.
The sacrament of the Holy Eucharist was instituted as a food, a spiritual food.
Union with the Lord
Since the Holy Eucharist is a spiritual food, it does for the soul what physical food does for the body.
When we eat physical food, it becomes united to us—it is changed into our own substance and becomes a part of us.
In Holy Communion something analogous happens to us spiritually, but with a great difference: in this case it is the individual who is united to the Food, not the Food to the individual. The lesser is united to the Greater.
We become one with Christ.
This sacramental union of ourselves with Jesus is more than the mere physical union between our body and the Sacred Host which we have swallowed. More importantly, it is a mystical and spiritual union of the soul with Jesus. This is produced in the soul by our physical contact with the sacred Body of Jesus.
This marvelous blending of the soul with Jesus is a very special kind of union. Obviously we do not become “part of God.” It is much more than the “ordinary” union with God which the Holy Spirit establishes in us by sanctifying grace. Yet it is less than the ultimate and most intimate union with God which will be ours in the beatific vision in heaven.
This union is simply called Communion.
The Mystical Body
Being united with Christ in this close and personal union, we are necessarily united also with all others who are “in” Christ—all others who are members of His Mystical Body.
Union with Christ in Holy Communion is the bond of charity which makes us one with our neighbor.
When we grow in love for God through our union with Jesus, we also necessarily grow in love for our fellow man. If we have the right dispositions, our Holy Communions should produce fruits in ourselves that we notice over time: a lessening of racial and national prejudices, of neighborhood resentments; an increase in neighborliness, in compassion, in patience and forbearance towards others.
The very sign of the sacrament symbolizes our total oneness in Christ:
- Many grains of wheat have been compounded together to make the one bread which has become the Body of Christ.
- Many grapes have been crushed together in the press to make the contents of the one chalice which has become the Blood of Christ.
We are many in One—and that One is Christ.
“And the bread that we break,” says St. Paul, “is it not the partaking of the body of the Lord? Because the bread is one, we though many, are one body, all of us who partake of the one bread” (1 Corinthians 10:17).
Communion’s sacramental grace
It is characteristic of every sacrament either to give or to increase sanctifying grace.
Each of the other sacraments however has a specific purpose of its own in addition to the bestowal of sanctifying grace:
- Baptism cleanses from original sin
- Penance forgives mortal sin
- Confirmation strengthens faith
- Matrimony sanctifies marriage…
…and so on.
But in the Holy Eucharist we have the one sacrament whose principal purpose is to increase sanctifying grace, repeatedly and often, through personal union with the Giver of grace Himself.
That is why the Holy Eucharist is preeminently the sacrament of spiritual growth, of increase in spiritual stature and strength.
A state of grace is required
That also is why the soul already must be in the state of sanctifying grace when we receive Holy Communion—in other words, free from mortal sin.
Physical food cannot benefit a dead body, and the Holy Eucharist cannot benefit a dead soul.
Indeed, a person who knowingly would receive Holy Communion while in the state of mortal sin, would add a new dimension of guilt to his already sinful state: he would commit the grave sin of sacrilege. In the very act of outwardly offering himself to Jesus for the union-in-love which is the essence of Holy Communion, he would be opposing Jesus by that rejection of God which is inherent in all mortal sin.
A grace that protects
However, the reception of the Holy Eucharist will forgive venial sin—presuming of course that the communicant has sorrow for his venial sins.
Here again it is love that does the work. What we might call the “charge” of love which Jesus unleashes upon the soul in this moment of personal union, is a purifying force; it purges the soul from all lesser infidelities. Whatever accumulation of venial sin may encumber the soul, it is dissolved and annihilated (if repented) as Christ’s love makes contact with the soul.
Another effect of Holy Communion is to preserve the soul from spiritual death, to preserve the soul from mortal sin.
The strength of our inclination to sin (called concupiscence) is also reduced each time we receive the sacrament of the Holy Eucharist.
A rich banquet of the Lord
Holy Communion unites us with Christ and intensifies our love for God and for neighbor.
It increases sanctifying grace. It remits venial sin, lessens concupiscence, and thus preserves us from mortal sin.
Finally, as good food should, it readies us for work. A frequent communicant who receives worthily and fruitfully cannot possibly remain wrapped up in himself. As love for Christ more and more fills his horizon, he feels the urge to do things for Christ and with Christ. Powered by the graces of Holy Communion, he becomes an apostolic Christian.
Holy Communion is indeed the Bread of Life, a banquet overflowing with grace and richness:
