Of Strife
Of Strife — St. Thomas Aquinas asks: Whether strife is always a sin?; Whether strife is a daughter of anger?.
We must now consider strife, under which head there are two points of inquiry:
Article 1: Whether strife is always a sin?
Strifes [*The Douay version has 'quarrels'] are reckoned among the works of the flesh (Gal. 5:20), and "they who do such things shall not obtain the kingdom of God." Therefore strifes are not only sinful, but they are even mortal sins.
While contention implies a contradiction of words, strife denotes a certain contradiction of deeds. Wherefore a gloss on Gal. 5:20 says that "strifes are when persons strike one another through anger." Hence strife is a kind of private war, because it takes place between private persons, being declared not by public authority, but rather by an inordinate will. Therefore strife is always sinful. In fact it is a mortal sin in the man who attacks another unjustly, for it is not without mortal sin that one inflicts harm on another even if the deed be done by the hands. But in him who defends himself, it may be without sin, or it may sometimes involve a venial sin, or sometimes a mortal sin; and this depends on his intention and on his manner of defending himself. For if his sole intention be to withstand the injury done to him, and he defend himself with due moderation, it is no sin, and one cannot say properly that there is strife on his part. But if, on the other hand, his self-defense be inspired by vengeance and hatred, it is always a sin. It is a venial sin, if a slight movement of hatred or vengeance obtrude itself, or if he does not much exceed moderation in defending himself: but it is a mortal sin if he makes for his assailant with the fixed intention of killing him, or inflicting grievous harm on him.
Article 2: Whether strife is a daughter of anger?
Gregory says (Moral. xxxi, 17) that "anger gives rise to strife"; and it is written (Prov. 15:18; 29:22): "A passionate man stirreth up strifes."
As stated above (), strife denotes an antagonism extending to deeds, when one man designs to harm another. Now there are two ways in which one man may intend to harm another. In one way it is as though he intended absolutely the other's hurt, which in this case is the outcome of hatred, for the intention of hatred is directed to the hurt of one's enemy either openly or secretly. In another way a man intends to hurt another who knows and withstands his intention. This is what we mean by strife, and belongs properly to anger which is the desire of vengeance: for the angry man is not content to hurt secretly the object of his anger, he even wishes him to feel the hurt and know that what he suffers is in revenge for what he has done, as may be seen from what has been said above about the passion of anger (). Therefore, properly speaking, strife arises from anger.
