Questions about Holy Communion
366. What is Holy Communion?
Holy Communion is the receiving of Jesus Christ in the sacrament of the Holy Eucharist.
(a) Just as it is necessary to nourish our bodies with material food, so also it is
necessary to nourish our souls with spiritual food. Our Divine Savior so loved us that He
gave us Himself in the sacrament of the Holy Eucharist; He gave us His own body and blood
as food for our souls.
(b) It is not necessary that we receive Our Lord's body and blood under the appearances
of both bread and wine. Christ is entirely present under the appearances of bread, and
also entirely present under the appearances of wine. Therefore, we receive Him whole and
entire under the appearances of bread alone or of wine alone.
(c) In some Eastern Churches the faithful receive Holy Communion under the appearances
of both bread and wine. In the Western Church the faithful receive Communion most commonly
under the appearances of bread, with the Precious Blood generally reserved by law to
special feasts or other particular circumstances.
367. What is necessary to receive Holy Communion worthily?
To receive Holy Communion worthily it is necessary to be free from mortal sin, to have
a right intention and to obey the Church's laws on the fast required before Holy Communion
out of reverence for the body and blood of Our Divine Lord. However, these are some cases
in which Holy Communion may be received without fasting.
(a) Venial sin does not make us unworthy of receiving Holy Communion; but it does
prevent us from receiving the more abundant graces and blessings which we would otherwise
receive from Holy Communion.
368. Does he who knowingly receives Holy Communion in mortal sin receive the body
and blood of Christ and His graces?
He who knowingly receives Holy Communion in mortal sin receives the body and blood of
Christ, but he does not receive His graces and commits a grave sin of sacrilege.
(a) To receive Holy Communion unworthily is a serious abuse of the sacred body and
blood of the Lord, and therefore a sacrilege.
369. What should we do to receive more abundantly the graces of Holy Communion?
To receive more abundantly the graces of Holy Communion we should strive to be most
fervent and to free ourselves from deliberate venial sin.
370, What are the current rules for fasting before Holy Communion?
(a) For many centuries the Church commanded a strict fast from midnight before one
could receive Holy Communion. However, in the 1950's Pope Pius XII introduced a much more
lenient form of fasting before Holy Communion in order to give Catholics an opportunity to
receive Holy Communion more frequently.
(b) Pope Pius XII also allowed the celebration of afternoon and evening Masses every
day, when the spiritual good of a considerable number of the faithful requires it. It is
the right of the bishop of each diocese to decide when such Masses may be offered in his
(c) Paul VI further reduced the fasting requirement after the Second Vatican Council,
requiring only a one hour fast from all food and drink (excluding water). This may be
reduced to 15 minutes for those who are sick or for other important reasons. This is the
practice currently in force.
371. When may Holy Communion be received without fasting?
Holy Communion may be received without fasting when one is in danger of death, or when
it is necessary to save the Blessed Sacrament from insult or injury.
(a) Ordinarily the danger of death comes from sickness or injury. But it is not
necessary that a person be in danger of death from sickness in order to receive Holy
Communion without fasting. The danger of death may come from some other cause. A soldier,
for example, who is about to go into battle or a person about to be executed may receive
Holy Communion without fasting.
373. How should we prepare ourselves for Holy Communion?
We should prepare ourselves for Holy Communion by thinking of Our Divine Redeemer whom
we are about to receive, and by making fervent acts of faith, hope, love, and contrition.
(a) We should be neat, clean, and modest in our appearance, and respectful and reverent
in our manner.
(b) Each time we receive Holy Communion we should try to be as devout and fervent as if
it were the only Communion of our lives.
374. What should we do after Holy Communion?
After Holy Communion we should spend some time adoring Our Lord, thanking Him, renewing
our promises of love and of obedience to Him, and asking Him for blessings for ourselves
375. What are the chief effects of a worthy Holy Communion?
The chief effects of a worthy Holy Communion are:
first, a closer union with Our Lord and a more fervent love of God and of our neighbor;
second, an increase of sanctifying grace;
third, preservation from mortal sin the and remission of venial sin;
fourth, the lessening of our inclinations to sin and the help to practice good works.
376. When are we obliged to receive Holy Communion?
We are obliged to receive Holy Communion during Easter time each year and when in
danger of death.
377. Why is it well to receive Holy Communion often, even daily?
It is well to receive Holy Communion often, even daily, because this intimate union
with Jesus Christ, the Source of all holiness and the Giver of all graces, is the greatest
aid to holy life.
378. How should we show our gratitude to Our Lord for remaining always on our altars
in the Holy Eucharist?
We should show our gratitude to Our Lord for remaining always on our altars in the Holy
Eucharist, by visiting Him often, by reverence in church, by assisting every day at Mass
when this is possible, by attending parish devotions, and by being present at Benediction
of the Blessed Sacrament.
(a) Benediction of the Blessed Sacrament is a ceremony in which the sacred host is
exposed for a time on the altar, usually in the monstrance. During Benediction the priest
blesses the people with the sacred host.
(b) The monstrance, or ostensorium, is a large vessel in which the host is exposed to
view through a glass-covered opening in the center.
(c) The long cloak-like vestment worn by the priest at Benediction of the Blessed
Sacrament is called a cope. The humeral veil is placed over the priest's shoulders before
he gives the blessing.
