(a) The law speaks of eating, that is, of solid food, and hence the Lenten and other similar fasts are not broken by liquids which are beverages rather than foods, or which are used to allay thirst, or carry food or assist digestion, and not chiefly to nourish (e.g., water, teas, coffee, light cocoa, wine, beer, lemonade, fruit juice). Likewise, sirups taken as medicines are not considered foods, even though they contain nourishment, unless one drinks a large quantity for its food content. Light ices may be considered drink, but ice-cream is food. On the contrary, liquids that are chiefly nourishing are regarded as food (e.g., soup, oil, honey). Finally, some liquors vary between food and drink, according to their richness or weakness, their great or small quantity. Thus, hot chocolate as made in the United States contains only a small amount of solid and may be considered as a drink, but as made in Europe it is stronger and rather food than drink.
(b) The law admits as an indulgence on fast days, in addition to the one meal, a small breakfast in the morning and a light collation to be taken either around noon (lunch) or in the evening (supper). The quality and quantity of these two repasts are left to local custom. The Uniform Norm for Fast and Abstinence in the United States adopted by the Hierarchy, Nov. 14, 1951, establishes the following norm for these two meatless meals. They are to be “sufficient to maintain strength, may be taken according to each one’s needs; but together they should not equal another full meal.” This norm, called the relative standard, was adopted by many Bishops of the United States, beginning with Lent of 1952. Thus, the amount of food is dependent to some degree on a person’s own needs and appetite. The relative standard is distinguished from the absolute norm which allows about two ounces for the morning collation and eight ounces for the evening.
(c) The law permits one to eat but once in the day (exception being made for breakfast and collation), but it places no limits as to the quality of the food at the principal meal (unless the day be also a day of abstinence, when meat is forbidden), or as to its quantity, though temperance bids one to eat at all times in moderation. On fast days, therefore, one may not eat between meals, nor so divide or prolong the dinner that it really becomes several meals. A notable interruption (two or three hours) made without good reason divides a dinner into two meals, and over two hours of uninterrupted eating, under ordinary circumstances, seems to be more than the one full meal which the law allows.
2589. The Obligation of the Precept of Fasting.—(a) Origin.—The natural law commands fasting in general, since without some kind of austerity above common temperance certain desirable ends (such as atonement for past transgressions, conquest of unruly passions, and elevation of the soul) cannot be attained; and as these ends are necessary it is also necessary to use the means as far as one needs them. The particularization of this natural law has been made by the positive law of the Church, and with such wisdom as to promote the good of both soul and body. The times appointed are most appropriate (e.g., the season when the Passion is commemorated, Luke, v. 35); the duration of the long fast is modelled on that of Christ (Matt., iv. 1); the curtailment of food required is not only beneficial (as an exercise of self-control and a rest and change to the metabolism), but is moderate, since it permits sufficient food for the day, and even in the fast of Lent the Sundays occur to give a respite.
(b) Gravity.—The precept of fasting is grave, both from the purpose of the law (see 2469), and from the express declaration of the lawgiver (Denzinger, n. 1123). But the spirit of the precept is not notably deviated from by every transgression, and hence even in reference to matter there are minor or venial violations; and moreover the precept is probably (unlike that of abstinence) an indivisible one, since it consists in the limitation to one meal, and hence it cannot be violated more than once a day. Grave matter, when the absolute norm is used, seems to be about four ounces added to the collations or taken between meals, either all at once or at different times during the day (Denzinger, n.1129), But if the relative norm is used, a greater quantity is needed to establish grave matter, e.g., one fourth of a full meal. But he who has broken his fast (e.g., by a second full meal) does not break it again by a third or fourth full meal on the same day, for after the second full meal the fast has become impossible for that day. He who accidentally takes too much at breakfast can still keep the fast by proportionately diminishing his evening repast.
(c) Exceptions.—Physical or moral impossibility excuses from the fast, and gives the right to eat meat as often as moderation allows on days that are not meatless days. The chief persons who labor under impossibility are those who are too weak to fast (e.g., the sick, the convalescent, pregnant and nursing mothers, the nervous), those who are too poor to get one square meal a day (e.g., street beggars who have nothing may eat as often as they are given an alms, if it does not buy them a dinner), and those who cannot do their necessary or customary hard work if they fast. Hard work is such as is exercised for many hours continuously, or for a less time if it is very intense, and which is greatly fatiguing to the mind (e.g., daily teaching, lecturing, studying, hearing confessions, preaching, etc.) or to the body (e.g., heavy manual labor, the difficult jobs in offices or stores, work that requires one to be on one’s feet for hours at a time, necessary journeys made under hardship). The confessor or physician can decide about cases of impossibility that are not manifest, but dispensation should be had from the pastor (Canon 1245). Those who are dispensed from the ecclesiastical fast or abstinence should remember that they are not dispensed from the natural law of temperance, and they should practise some abstemiousness according to their ability (e.g., by self-denial in alcoholic beverages, tobacco, sweets, etc., or mortification in the quantity or quality of food).
2590. The Third Precept of the Church.—This precept commands that all the faithful, male and female, who have reached the age of discretion go to confession at least once a year (Canon 906).
(a) The subject of this precept is every baptized person who has entered the Church through valid Baptism and who has the use of reason, which begins usually at the age of seven. Infants are incapable of committing sin, and the unbaptized are incapable of receiving the Sacrament of Penance.
(b) The matter of the precept is a good sacramental confession of the grave sins not yet confessed, made with the purpose of obtaining absolution to any duly authorized priest. Hence, those who have only venial sins on their conscience are not bound according to the common opinion by this precept, and, on the other hand, those who make a sacrilegious or voluntarily null confession do not fulfill the law (Denzinger, n. 1114; Code, Canon 907). It seems that one who, after a confession of venial sins at Easter, falls into grave sin is not bound from this precept to confess again before the end of the year.
(c) The time for fulfillment of the precept is once during the year. The law leaves one free to confess on any day during the twelvemonth, and to count the year either civilly (i.e., from January 1 to December 31), or ecclesiastically (e.g., from Easter time to Easter time, as is commonly done), or from the date of the last confession. The limit is set, however, not to terminate but to insist upon obligation, and hence it seems that he who has not made his 1957 confession must make it as soon as possible in 1958, but the 1957 confession made in 1958 will satisfy for the 1958 obligation also (see 468 sqq.).
