contracts marriage, while ignorant that he and the other person are first cousins, is invalidly married.
(b) Affected ignorance of ecclesiastical law or of the penalty alone does not excuse from any penalties latae sententiae (Canon 2229, §1).
(c) If the law contains the following words: praesumpserit, ausus fuerit, scienter, studiose, temerarie, consulto egerit, or others similar to them which require full knowledge and deliberation, any diminution of imputability on the part of either the intellect or the will exempts the delinquent from penalties latae sententiae (Canon 2229, §2). (d) If the law does not contain such words, crass or supine ignorance of the law or even of only the penalty does not exempt from any penalty latae sententiae; ignorance that is not crass or supine exempts from medicinal penalties, but not from vindicative penalties latae sententiae (Canon 2229, §3, 1°).
491. Other specific determinations of the law include: (a) Inculpable ignorance of the law itself excludes moral imputability (Canon 2202, §1); actual inculpable inadvertence or error in regard to the law has the same effect (Canon 2202, §3). (b) Culpable ignorance, or culpable inadvertence, or error concerning the law or concerning the fact diminish imputability more or less in proportion to the culpability of the ignorance (Canon 2202, §1). (c) If the ignorance, even inculpable, affects only the fact of the existence of the penalty, it does not exclude imputability of the delict, but it does diminish it (Canon 2202, §2).
492. Absolute or physical impossibility (i.e., the want of the power or of the means of complying with a law), of course, excuses from its observance; for no one is bound to what is impossible. This applies to divine law, and hence much more to human law. Example: He who is unable to leave the house is not obliged to go to Mass.
493. Moral impossibility—that is, the inability to comply with the law without extraordinary labor, or the imminent danger of losing a notable good or of incurring a great evil—does not excuse from the observance of ecclesiastical law when this law receives through circumstances the added force of the negative law of nature. This happens when the evil that will result through the observance of the law bears no proportion to the evil that will result from its violation, the former being private or temporal or human, the latter public or spiritual or divine; for the law of nature forbids that the common welfare, or the salvation of a soul, or the honor of God be sacrificed for the benefit of an individual, or for the life of the body, or for the welfare of a creature. Example: The command to abstain from meat on Friday obliges, if one has been ordered to violate it as a sign of contempt of God or of religion, even though death is threatened for refusal.
494. Moral impossibility excuses from the observance of a human law in the following cases:
(a) One is excused when a considerable loss in health, reputation, spiritual advantage, property, etc., or a grave inconvenience will result from observing a law which is not a prohibition of nature in the sense of the previous paragraph; for the legislator cannot impose obligations that are needlessly heavy, and hence positive law does not oblige in case of such moral impossibility. Example: Our Lord reproved the inhuman rigor of the Pharisees, who insisted that their regulations must be observed, whatever the difficulty or cost.
(b) One is excused when a lower or less urgent law is in conflict with a law that is higher or more urgent. In such a case the greater obligation prevails, and the lesser obligation disappears. Examples: The divine laws that one must preserve one's life or administer Baptism to a dying person prevail over the human law of attendance at church. The less urgent law of fasting yields to the more urgent law of devoting oneself to duties required by one's state of life, if there is a conflict between the two laws.
495. The loss, evil or inconvenience that constitutes moral impossibility with respect to a law, must bear a proportion to the law itself; and hence the higher or the more imperative the law, the greater must be the reason that suffices to excuse from it.
496. Only a learned and prudent man can determine whether moral impossibility exists with reference to a particular case, and hence it would be dangerous for those who are not theologians to decide, either for themselves or for others. The points that have to be considered in judging are: (a) whether or not the difficulty is of a gravity proportionate to the importance of the law (e.g., a graver reason is required to excuse from a law that obliges under mortal sin than to excuse from a law that binds under light sin); (b) whether or not the difficulty is grave in relation to the person concerned (e.g., an obligation that is easy for a healthy person may be very difficult for one who is infirm).
497. It is never lawful to bring about either physical or moral impossibility of observing a law, if this be done with the sole or principal purpose of escaping one's duty. Example: To go away on Saturday in order to avoid Mass on Sunday.
498. It is lawful to cause impossibility of observing a law, if there be some sufficient reason for doing this; for it is lawful to do something from which two effects, one good and the other bad, result, if the good effect is the one intended, and there is a sufficient reason for permitting the evil effect (102 sqq.). Example: It is sometimes lawful to do some extra work that is very useful, even if the labor makes one unable to observe a fast.
499. The sufficient reason spoken of in the last paragraph is one that is proportionate to the urgency and importance of the command and to the frequency of the non-observance. Examples: A greater reason is required to take up some work which will make it impossible to keep the fast, if this be done on the fast day itself, than if it be done the day before. A far greater reason is required to take up some work that makes the observance of the fast impossible, if this happens frequently or habitually, than if it happens only once or twice.
500. Cessation of Law.—A law ceases in two ways.
(a) It ceases from without (i.e., from the act of the legislator), when he abolishes it, by total or partial revocation (abrogation, derogation), or by the institution of a new law directly contrary to it (obrogation). In the new Code of Canon Law there are many instances of revocation or obrogation of older legislation (see Canons 22, 23), as in the matter of censures and matrimonial impediments. Examples: In the diocese of X a minor feast was made a holyday of obligation. This law was abrogated, if later on it was decreed that neither the prohibition against servile works nor the precept of hearing Mass was obligatory for that feast; it was derogated from, if later it was decreed that servile works were permitted, but Mass was obligatory for that day; it was obrogated, if a later law included the minor feast in a list of special days of devotion for which the hearing of Mass was recommended.
(b) A law ceases from within (i.e., of itself), when through change of conditions the purpose for which it was made no longer exists, or is no longer served by the law.
501. The purpose for which a law was made ceases to be served by the law in two cases.
(a) A law no longer serves its purpose, if, from having been a benefit, it has become a detriment, inasmuch as its observance now would be wicked, or impossible, or too burdensome. In this case the law ceases, since it is now contrary to the supreme law that the common welfare be promoted. Example: A particular law forbade the use of fat or grease in the preparation of food on days of abstinence. Later, it became impossible to procure the substitutes previously used.
(b) A law no longer serves its purpose, if, from having been useful, it has become useless, inasmuch as it is no longer necessary for the end intended by the lawgiver. In this case the law ceases, for regulations should not be imposed needlessly. Example: The Council of Jerusalem made a law that the faithful should abstain from using as food animals that had been strangled (Acts, xv. 20). The purpose of the law was to avoid offense to the Jewish converts, who at that time formed a large part of the Christian community and who had a religious abhorrence for such food. But shortly afterwards, the Gentile element having become stronger in the Church, no attention was paid to ceremonial rules of Judaism.
502. A law ceases to serve its purpose also as follows:
(a) The law becomes harmful or useless with reference to the purpose of the lawgiver generally and permanently, if the changed conditions affect the whole community or the great majority, and are lasting. In this case the law ceases; for, since it is made for the community as a whole and as a lasting ordinance, it cannot endure, if it
