The minimum legal requirement in force for the present time is set out here for your information; however, it must be remembered that living the Catholic Faith requires far more than accomplishing the bare minimum.
The 1983 Code of Canon Law (Canon 919 §1) legislates: “Whoever is to receive the blessed Eucharist is to abstain for at least one hour before Holy Communion from all food and drink, with the sole exception of water and medicine.” The change from the former, mitigated discipline introduced by Pope Pius XII in the Apostolic Constitution Christus Dominus (January 6, 1953) was made by Pope Paul VI in the decree Attentis Multarum of November 21, 1964. Legislation of January 29, 1973, shortened the fast from solid food and drink for the sick and aged and those tending them to a quarter of an hour. Hence, for the reception of Holy Communion, the following rules apply:
- WATER may be taken AT ANY TIME.
- SOLID FOOD and DRINKS may be taken up to one hour before Holy Communion. For the sick and aged and those who tend them, solid food and drinks may be taken up to a quarter of an hour before.
- The sick (not necessarily bed-ridden) may also take genuine medicines, solid or liquid, as well as non-alcoholic drinks at any time before Holy Communion.
Nevertheless, the faithful who are in a position to do so are exhorted to observe either the old form of Eucharistic Fast before Holy Communion, which entailed total abstinence from food or drink, including water, from midnight; or else the mitigated fast legislated by Pope Pius XII of abstinence from solid food and alcoholic drinks for three hours, and non-alcoholic drinks for one hour before.
FASTING BEFORE MASS
Author: Father Edward McNamara, LC
ROME, 5 JULY 2011 (ZENIT)
Legionary of Christ Father Edward McNamara, professor of liturgy at the Regina Apostolorum university.
The discipline of fasting before communion has a long history, as Pope Pius XII states in his 1953 apostolic constitution, “Christus Dominus” —
“From the very earliest time the custom was observed of administering the Eucharist to the faithful who were fasting. Toward the end of the fourth century fasting was prescribed by many Councils for those who were going to celebrate the Eucharistic Sacrifice. So it was that the Council of Hippo in the year 393 issued this decree: ‘The Sacrament of the altar shall be offered only by those who are fasting.’ Shortly afterward, in the year 397, the Third Council of Carthage issued this same command, using the very same words. At the beginning of the fifth century this custom can be called quite common and immemorial. Hence St. Augustine affirms that the Holy Eucharist is always received by people who are fasting and likewise that this custom is observed throughout the entire world.
“Doubtless this way of doing things was based upon very serious reasons, among which there can be mentioned first of all the one the Apostle of the Gentiles deplores when he is dealing with the brotherly love-feast of the Christians. Abstinence from food and drink is in accord with that supreme reverence we owe to the supreme majesty of Jesus Christ when we are going to receive Him hidden under the veils of the Eucharist. And moreover, when we receive His precious Body and Blood before we take any food, we show clearly that this is the first and loftiest nourishment by which our soul is fed and its holiness increased. Hence the same St. Augustine gives this warning: ‘It has pleased the Holy Ghost that, to honor so great a Sacrament, the Lord’s Body should enter the mouth of the Christian before other food.’
“Not only does the Eucharistic fast pay due honor to our Divine Redeemer, it fosters piety also; and hence it can help to increase in us those most salutary fruits of holiness which Christ, the Source and Author of all good, wishes us who are enriched by His Grace to bring forth.”
Before the time of Pius XII the Eucharistic fast was from midnight onward and included water. This also meant that Masses were only celebrated in the morning.
In the above-mentioned constitution the Pope, while stressing the importance of the fast, affirmed:
“It should nevertheless be noted that the times in which we live and their peculiar conditions have brought many modifications in the habits of society and in the activities of common life. Out of these there may arise serious difficulties which could keep men from partaking of the divine mysteries if the law of the Eucharistic fast is to be observed in the way in which it had to be observed up to the present time.”
Pius XII mentions some of the difficulties preventing many from receiving Communion. Among them are the shortage of clergy, especially in mission lands, and the pace of modern life in factories and offices which include night shifts. He also desired to open up the possibility of celebrating Mass in the evening on important feasts so that more people could attend.
Thus, among other things he established that water and medicine would no longer break the fast. He also mitigated the fast under certain circumstances. In 1957, with the document “Sacram Communionem,” he changed the law again, to require only a three-hour fast.
Pope Paul VI brought in the present discipline in November 1964, and this forms the basis of Canon No. 919.
Council of Trent, sess. 13, (Decretum de SS. Eucharistiae Sacramento) cap. 7: Denz-Schon 1646-47
“It is unfitting to take part in any sacred function without holiness. Assuredly, therefore, the more that Christians perceive the sacredness and divinity of this heavenly sacrament, the more must they take every care not to come to receive it without reverence and holiness, especially since we have the frightening words of St. Paul: ‘For those who eat and drink unworthily, eat and drink damnation to themselves, not discerning the Lord’s body’ (1 Cor 11:29). Those wishing to receive communion must be reminded of St. Paul’s command: ‘Let a man examine himself’ (1 Cor 11:28). Church usage makes it clear that such an examination is needed because those conscious of mortal sin, no matter how contrite they may regard themselves, must not go to the eucharist without sacramental confession beforehand. This Council decrees that, when confessors are available, this practice must always be observed by all Christians, including priests obliged by office to celebrate Mass. A priest who in case of necessity has celebrated Mass without confessing beforehand must go to confession as soon thereafter as possible.”

RULES FOR FASTING & ABSTINENCE
“Unless you do penance, you shall likewise perish.” (Lk. 13:5)
To what purpose do we fast and abstain?1
- Because we are sinners, justice requires each of us to make recompense to God for the honor we have denied Him by our sins.
- Because we have misused our goods, our souls and bodies—as well as those of others—the natural law requires us to strive to restore the order we have disturbed by our sins. Thus, the Natural Law and the Divine Law bind us in a general way to perform acts of penance.
- In order to help us fulfil this requirement, Holy Mother Church, knowing our weakness and laziness, binds us under ecclesiastical laws to perform works of penance at certain times.
Throughout the centuries, these ecclesiastical laws have changed, sometimes becoming more strict, sometimes relaxing the discipline of penance. Regardless of changes to the Church laws, which exist to make our obedience to the natural and Divine laws of penance easier, the fundamental requirement remains: “Unless you do penance, you shall likewise perish.”
Considering the alternatives of unending bliss in heaven or unending misery in hell, and considering that the effects of original sin and of our own sins make us lazy and apt to forget our duty towards God, it seems much more reasonable to err on the side of too much penance, especially in times of relaxed Church discipline such as our own, rather than on the side of too little.
Only the Church can hold us guilty of mortal sin for failing in this or that specific act of penance, but we can certainly offend God mortally by neglecting penance completely over a length of time. This principle should be kept in mind when deciding on concrete penitential practices in accordance with the requirements and guidelines listed below. “Rules for penitential days under present Church law” details the bare minimum of penance which we must accomplish if we are to hope to stay out of mortal sin.
Nevertheless, we will easily fall into mortal sin if we confine our entire penance for the year to those days and acts required by the current law. “Guidelines for traditional penitential practices” spells out the strongly recommended practices which were observed until just after the Second Vatican Council.
Rules for penitential days under present Church law
In 1966, Pope Paul VI promulgated a new set of regulations for fasting and abstaining by his apostolic constitution, Paenitemini. These new rules are listed in the 1983 Code of Canon Law, Canons 1249-1253 and all Roman Catholics are bound to strictly observe them.2
There are two sets of laws that apply to the Church’s penitential days:
- The law of abstinence: this refers to abstaining from meat.
- The law of fasting: this refers to the quantity of food taken, thus also refraining from eating between meals.
Who is bound to observe these laws?
- The law of abstinence binds all Catholics, beginning on the day after their 14th birthday.
- The law of fasting binds all adults (beginning on their 18th birthday) until the midnight which completes their 59th birthday.
What is forbidden and allowed to be eaten?
- The law of abstinence forbids the use of meat. This does not apply to dairy products, eggs, or condiments and shortening made from animal fat.
- The law of fasting allows only one full meal a day and two smaller meals. The two smaller meals should not equal the quantity of the main meal (which in the United States is customarily observed as the evening dinner).
- Eating between meals is not permitted, but liquids are allowed, including milk and fruit juices.
- Fish and all cold-blooded animals may be eaten (e.g., frogs, clams, turtles, etc.).
In the Universal Church
Obligatory days of fast and abstinence:
- Abstinence is obligatory on all Fridays, except on Solemnities (i.e., I Class Feasts).
- Fasting and abstinence are obligatory on Ash Wednesday and Good Friday.
In The USA
In Paenitemini, Pope Paul VI gave authority to the episcopal conferences on how the universal rules would be applied in their region. On November 18, 1966, the National Conference of Catholic Bishops legislated the following to be observed in the United States:
- Abstinence is obligatory on all Fridays of Lent, except Solemnities (i.e., I Class Feasts).
- Fasting and abstinence are obligatory on Ash Wednesday and Good Friday.
- Abstinence on all Fridays, though not obligatory under pain of sin, is “especially recommended.”
- Fasting on all weekdays of Lent, though not obligatory under pain of sin, is “strongly recommended.”
The local ordinaries also have authority to grant dispensations from these rules within their dioceses.
Guidelines for traditional penitential practices
Here are the traditional rules of fast and abstinence as observed per the 1962 liturgical calendar and outlined in Canons 1250-1254 of the 1917 Code of Canon Law:
Who was bound to observe these laws?
- The law of abstinence bound all Catholics, beginning on the day after their 7th birthday.
- The law of fasting bound all Catholics, beginning on the day after their 21st birthday and ending at the midnight which completed their 59th birthday. [Note: The USA’s particular law has lowered the obligatory fasting age to 18.]
What was forbidden and allowed to be eaten?
- The law of abstinence forbade the eating of flesh meat and of broth made of meat, but did not exclude the use of eggs, dairy products, or seasonings made from the fat of animals.
- The law of fasting prescribed that only one full meal a day was taken with two smaller meals that did not equal the main one.
- As to the kind of food and the amount that might be taken, the approved customs of the place were to be observed. It was not forbidden to eat both flesh meat and fish at the same meal, nor to interchange the midday and evening meals.
In the Universal Church:
- Abstinence was obligatory on all Fridays, except on Holy Days of Obligation outside of Lent.
Fasting and complete abstinence were obligatory on the following days:
- Ash Wednesday
- Fridays and Saturdays in Lent
- Good Friday
- Holy Saturday (until midnight 1)
- Ember Days (Wednesday, Friday and Saturday)
- Vigil of Pentecost
- Vigil of Christmas
- [NB: both the Vigils of the Immaculate Conception and All Saints were omitted from the 1962 calendar]
Partial abstinence:
Fasting and partial abstinence were obligatory on all other weekdays of Lent (i.e., Monday through Thursday—Friday was always complete abstinence); this meant that meat could be eaten at the principal meal on these days.
Some further clarifications to universal laws:
There are few more distinctions to take into account fasting and abstaining when a usual fast day was in concurrence with a Sunday (always a non-fast day):
- Sundays throughout the year and Holy Days of Obligation outside of Lent cancelled the fasting and/or abstinence of any penitential day which coincided.
- If a fast-day Vigil fell on Sunday, the fasting and abstinence associated with the Vigil were not anticipated on the Saturday, but dropped altogether that year.
Particular rules observed in the USA
On January 28, 1949, the United States bishops issued a statement modifying the regulations of fasting and abstinence in America (thus differing slightly from the universal laws) after receiving a ruling from the Sacred Congregation of the Council.
Fasting and partial abstinence was obligatory on the following days:
- Ember Wednesdays and Saturdays
- Vigil of Pentecost
- all other weekdays of Lent including Saturdays
Liquids, including milk and fruit juices, might be taken at any time on a day of fast, but “other works of charity, piety, and prayer for the pope should be substituted” to compensate for this relaxation.
In 1951, Pope Pius XII gave an indult to the American bishops allowing them to dispense with Abstinence on any penitential day that was a civic holiday and on the Friday that followed Thanksgiving Day. (Canon Law Digest, vol. 1.)
The United States bishops had the faculties to dispense the faithful from the obligation to fast and abstain on penitential days that fell on civic holidays.
Holy Days of Obligation in the USA
A Holy Day of Obligation is a day on which we are bound to hear Mass and to abstain from servile works. In the USA, the Holy Days of Obligation are:
- All Sundays
- Octave Day of the Nativity ( January 1)
- Ascension Day
- Assumption of the Blessed Virgin Mary (August 15)
- Feast of All Saints (November 1)
- Immaculate Conception (December 8)
- Christmas Day (December 25)
Lenten Mortification: a Reflection on the Season of Lent
Originally PUBLISHED in the February 2010 FSSP Newsletter
During the holy season of Lent, Holy Mother Church encourages us to spend forty days growing in knowledge of ourselves, so that, by our penance, we may better understand the exalted value of the soul over the body. By means of prayer, fasting, and almsgiving, the desires of the body are placed in subjection to the higher faculties of the intellect and will: By prayer we elevate our minds to God, by fasting we lessen our desire for pleasure, and by almsgiving we curb our love of money.
By fasting forty days in the desert, Our Lord, too, showed that there are benefits of denying the senses and appetites what is morally permitted them. Furthermore, the saints have testified that the detachment from creation (possessions, people, enjoyments) is absolutely necessary to arrive at perfection, for it is typical that God completes the purification of the soul only after it has expended great time and effort doing so by ordinary means. Thus, it is our obligation to mortify our senses and passions so that the soul’s capacity for her Creator is not otherwise occupied with His creation.
It should be noted that “to mortify” does not mean that we annihilate our senses, appetites, or passions; rather, we practice self-denial or privation in order to orient all desires and appetites towards God and make Him the sole desire (object) of our heart, mind, body, and soul.
Besides the senses and appetites of the body, the higher faculties of the intellect and will must also be purified. The intellect apprehends the true and presents it to the will as a good thing to pursue out of love. Thus, the action of the will is to love what the intellect says is good. But since the fall of Adam, the intellect has been darkened and the will has been weakened to the point where the will is inclined to selfishness and seeks to love that which the intellect can erroneously perceive as a good.
The superiority of the soul over the body means that the mortification of the will—the rational appetite—is even more important than the mortification of the body.
Contrarily, when the will embraces that which it should not, this turning away from God and towards creation is called sin. As sin resides in the will, it is the home of our faults and needs to be purified in order to regain strength to love purely the One Who is All-good, God.
When the free will is not properly ordered, the person lives for himself, seeking his own gratification in this world. Excessive self-centeredness subdues the soul so that sufferings and hardships are not willingly endured; fraternal correction and advice are not heeded; and pride, disobedience, and impatience develop deep roots in the soul. This inordinate self-love causes the person to abhor mortification. To express it in scientific terms, the person thinks that the world is not geocentric or heliocentric, but rather egocentric.
Hence, it is extremely important to mortify the will to combat pride and to lessen excessive love of self. Ultimately, the more the intellect understands the baseness of anything temporal (for example, the body) compared with the importance of the eternal (our soul, God), the greater the will turns to God in love. For it is only in her humility that the soul recognizes that without God, she is nothing.
As Lent is upon us, the resolution to maintain a stricter guard over our appetites ensures that the intellect and will are properly maintained as the sovereign faculties. In closely examining the giving up of some food, we recognize that there will be a corresponding suffering in the body. The growth in sanctification from this mortification is not so much in the pain itself; rather, it is in the intention of the will to embrace the suffering out of love for God. And such is the power of love (charity): it takes a finite act and produces an infinite value. Hence, in all that we do in daily life, if borne out of love for God or in union with Christ Crucified, the action produces a hundred-fold merit, based upon the charity God sees in our intention. This is why the widow who gave two mites gave more than all others: it is because she gave out of charity.
But great pain can reside in the will, more so than pain in the body. If a person were to hit us, the physical pain may subside in a few minutes, but deep down inside, the will can hold onto the emotional or intellectual pain. At times, the mind can take this memory and actually increase the suffering so that by recalling the incident, the person increases his pain. If that pain continues to grow in one’s mind or heart, and the will decides to remain offended instead of forgiving, then the mental, emotional, or spiritual health of that person is at risk.
We witness this phenomenon in the Western world: The notion of “I do what I want” is so prevalent that when we have to do something or endure something which we do not want to do, we feel violated or helpless. Such feelings, if not dealt with properly, remove joy from a soul, replace it with anger, bitterness, and even hatred towards other people—or even God. Ultimately, a society which overly emphasizes doing one’s will produces a culture which abhors authority, whether parental, governmental, or ecclesiastical.
For how dare another tell me what I should do? “I have my own will.” This rebellion to get our own way is readily seen in most children in their first years of life. When a child does not get his way, he throws a tantrum. Thus, it is incumbent upon parents to admonish, teach, and lead by example that there are many times in life when we have to do things which we prefer not to do. By such instruction, children will grow up to better respect proper authority, such as their parents and the Church, and thereby to use their will properly to choose good and avoid evil.
Because we live in a world where temptations abound, we are further required continually to monitor our will, chastise it when disordered, and re-direct it to the good when it fails. As this requires mortification, we annually employ the Lenten days of penance to maintain the will within its proper boundaries.
Furthermore, a pure motive for our penitential practices is also necessary for perfect union with God. Penance can be performed for less noble purposes, such as to lose weight or to seek the praise of others, or out of some Stoic attitude that emotions are beneath us. Yet, penance is more meritorious if done for the greater glory of God, or to conform our will to His Divine Will, or to strengthen the will over the senses, appetites, and passions of the body. The renewal of our pure motive will most likely have to be done throughout Lent in order to persevere in our good intention.
Lent is a time of not seeking or wishing anything other than to follow Christ Crucified and to give honor and glory to His Name, for the salvation of souls. So let us follow the advice of St. John of the Cross: “In order to arrive at having pleasure in everything, desire to have pleasure in nothing.”

Homily of St. Augustine, Bishop of Hippo
17th Tract on John
John 5:1-15
Let us see what is mystically signified by that one infirm man whom alone the Lord, keeping to a mysterious unity, chose out of so many sufferers, to be the subject of His healing power. He found in him a certain number of years of sickness. He had had an infirmity thirty and eight years. How this number is proper rather to weakness than to health, will now be the subject of a few careful remarks. I bespeak your attention; the Lord will be present, that I may speak fitly, and you may understand. The number forty is put before us as hallowed, and, in a way, perfect. I think that your love knoweth this God’s Scriptures often and; often witness it. Ye well know that a Fast of this number of days is hallowed. Moses fasted forty days. Elias did the same. And our Lord and Saviour Jesus Christ Himself fasted this number of days complete. Moses representeth the Law, Elias the Prophets, and the Lord the Gospel. And therefore these three appeared on the Mount of the Transfiguration. There the Lord showed Himself to His disciples with His Face shining as the sun, and His raiment glistering; and He stood between Moses and Elias; as it were, the Gospel receiving testimony, on the one hand from the Law, and, on the other, from the Prophets.
Whether, therefore, it be in the Law, or in the Prophets, or in the Gospel, the number of forty is recommended to us for Fast-days. The great and general Fast is this to abstain from the iniquity of the world, and her forbidden pleasures. This is the perfect Fast, that, denying ungodliness, and worldly lusts, we should live soberly, righteously, and godly in this present world. After such a Fast, what is the Feast that followeth? Hear what the Apostle saith in continuation Looking for that blessed hope, and the glorious appearing of our great God and Saviour Jesus Christ. (Titus ii. 12, 13.) We, then, make our pilgrimage in this world a Lent, by living good lives, and abstaining from her iniquities and her forbidden pleasures. But at the end of this life-long Lent there will be an Easter indeed. We look for that blessed hope, and the glorious appearing of our great God and Saviour Jesus Christ When that hope is realised, when that faith is swallowed up in knowledge, then indeed shall we receive every man a penny. In good sooth, it is true that every labourer in the vineyard will get his wages witness that Gospel which I believe ye have not forgotten, (Matth. xx. 116) and which it is not my business to quote again as if ye were ignorant children. Now, the word used in the original for this penny which the labourers received is denarion. And the derivation of the word denarion is the numeral decem, ten. There are forty days in Lent, and if we add ten, we get fifty. So do we toil in fasting for the forty days of Lent before Easter, and, then, when we have, as it were, received our reward, we keep holiday for the fifty days of Eastertide.
Remember how I remarked, that the man healed by our Lord at the pool of Bethesda had had an infirmity thirty and eight years. I wish to explain why this number of thirty-eight is proper rather to weakness than to health. Love is the fulfilling of the law (Rom. xiii. 10); to the fulfilling of the law belongeth in every work the number forty. But in love we have given us two precepts Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets. (Matth. xxii. 37-40). When the widow gave all she had for an offering to God she gave two mites (Mark xii. 42); the inn-keeper received two pence wherewith to cure him that had fallen among thieves (Luke x. 35); Jesus abode for two days among the Samaritans (John iv. 40), that He might establish them in love. When, then, anything good is spoken of as two, the two great divisions of love are the chief mystic interpretation. If, then, the law is fulfilled in the number forty, and it is not fulfilled if there be lacking the two precepts of love, what wonder is it that he was infirm who lacked two of forty?
