Change in the Gravity of Moral Defects

Change in the Gravity of Moral Defects.-An imperfection becomes a sin: (a) if the motive for omitting what is of counsel only is sinful (e.g., to neglect a Mass that is not of obligation out of contempt); (b) if a slight indeliberate transgression has a cause that was voluntary (e.g., involuntary distractions caused by previous neglect).

Venial sins become mortal when that which in itself is a slight offense, becomes in the individual agent a grave offense by reason of some change in the object or of some grave malice in the purpose, circumstances, or the foreseen results (see above 97 sqq.).

A change in the object makes venial sin mortal: (a) when that which is light matter objectively is apprehended subjectively as grave matter (e.g., a person tells a small lie or commits a trifling theft, thinking these to be mortal sins); (b) when that which is light matter by itself becomes knowingly grave matter through the additions that are made to it (e.g., a thief steals small amounts frequently with the intention of having a great amount of ill-gotten money after a time).

It should be noted that, while the matter of venial sins may coalesce so as to form grave matter and constitute a mortal sin, as just explained, venial sins themselves do not, from mere multiplication, ever become mortal, since the difference between mortal and venial sin is not one of quantity, but of kind. Hence, when acts are slightly sinful but do not coalesce, they multiply venial sins, but do not form mortal sin. Example: Coming a few minutes late for Mass every Sunday.

The multiplication of venial sins, especially when they are held as of no importance, disposes for the commission of mortal sin: (a) directly, by forming a habit that calls for ever greater indulgence (e.g., petty thefts lead to dishonesty on a large scale); (b) indirectly, by familiarizing one with wrongdoing and chilling the love for virtue.

The wrong purpose of the agent makes an act that is only venially sinful (as far as the object is concerned) to become mortally sinful, when the purpose contains a grave malice in itself, for the act is then intended only as a means to what is seriously wrong (see above 80). Example: To tell a small lie in order to break up friendships and sow hatreds.

The circumstances of an act that is only venially sinful in itself also make the act mortally sinful, when there is grave malice in such circumstances. Cases of this kind are the following:

(a) The circumstance of the person committing the sin sometimes changes the malice from light to grave. Example: Unbecoming levity in one in authority may cause serious disrespect for his office and thus be gravely sinful;

(b) The circumstance of the manner in which an act is performed may change it from a venial to a mortal sin, as when the sin is committed out of contempt, or is so coveted that it would be preferred to a grave obligation. Examples: One who violates a law of lesser moment, not because he regards it as bad, but because he wishes to show his disregard of all law and authority; or one who is so attached to games of chance that he is prepared to steal a large sum rather than give them up.

The serious harm that is foreseen as a result of venial sin also changes the malice from slight to serious. Examples: One who jokingly annoys another, knowing that this will provoke grave dissensions; or one who tells small lies to persons who are known for their uncharitable distortions and exaggerations; or one who agrees to take too much strong drink knowing from experience that this invariably leads to serious excess.

Mortal sins become venial when that which in itself is a grave offense, becomes light by reason of some change in he object or lack of full consent in the subject.

A change in the object makes a mortal sin venial: (a) when that which is grave matter objectively, is apprehended through inculpable, or only venially culpable ignorance as light matter (e.g., when an uninstructed child thinks that a serious calumny is only a venial sin); (b) when a sin whose character is serious but whose matter is divisible is small as to matter (e.g,, to be absent from a small part of the Mass on Sunday); (e) when a law whose obligation is grave will cause more than slight inconvenience in a particular case, and thus becomes of light obligation for that case (e.g., to miss Mass on Sunday because of a difficulty that was not unsurmountable, but yet considerable).

Lack of sufficient advertence or of full consent makes a mortal sin venial; (a) when without serious fault one does not advert to a gravely sinful act (e.g., a desire of revenge); (b) when without serious fault one does not know or does not think about the grave malice of what one is doing (e.g., to repeat a story, not knowing or not remembering at the time that it is a serious calumny); (c) when on account of considerable excitement, fear or other disturbance, one gives only partial consent to an act that is mortally sinful (e.g., when one, on being suddenly insulted, replies with a serious imprecation).
