Of Contention

Of Contention — St. Thomas Aquinas asks: Whether contention is a mortal sin?; Whether contention is a daughter of vainglory?.

We must now consider contention, in respect of which there are two points of inquiry:

Article 1: Whether contention is a mortal sin?

It is against the precept of the Apostle who says (2 Tim. 2:14): "Contend not in words." Moreover (Gal. 5:20) contention is included among the works of the flesh, and as stated there (Gal. 5:21) "they who do such things shall not obtain the kingdom of God." Now whatever excludes a man from the kingdom of God and is against a precept, is a mortal sin. Therefore contention is a mortal sin.

To contend is to tend against some one. Wherefore just as discord denotes a contrariety of wills, so contention signifies contrariety of speech. For this reason when a man contrasts various contrary things in a speech, this is called "contentio," which Tully calls one of the rhetorical colors (De Rhet. ad Heren. iv), where he says that "it consists in developing a speech from contrary things," for instance: "Adulation has a pleasant beginning, and a most bitter end."

Now contrariety of speech may be looked at in two ways: first with regard to the intention of the contentious party, secondly, with regard to the manner of contending. As to the intention, we must consider whether he contends against the truth, and then he is to be blamed, or against falsehood, and then he should be praised. As to the manner, we must consider whether his manner of contending is in keeping with the persons and the matter in dispute, for then it would be praiseworthy, hence Tully says (De Rhet. ad Heren. iii) that "contention is a sharp speech suitable for proof and refutation"---or whether it exceeds the demands of the persons and matter in dispute, in which case it is blameworthy.

Accordingly if we take contention as denoting a disclaimer of the truth and an inordinate manner, it is a mortal sin. Thus Ambrose [*Cf. Gloss. Ord. in Rom. i, 29] defines contention: "Contention is a disclaimer of the truth with clamorous confidence." If, however, contention denote a disavowal of what is false, with the proper measure of acrimony, it is praiseworthy: whereas, if it denote a disavowal of falsehood, together with an inordinate manner, it can be a venial sin, unless the contention be conducted so inordinately, as to give scandal to others. Hence the Apostle after saying (2 Tim. 2:14): "Contend not in words," adds, "for it is to no profit, but to the subverting of the hearers."

Article 2: Whether contention is a daughter of vainglory?

As stated above (), discord is a daughter of vainglory, because each of the disaccording parties clings to his own opinion, rather than acquiesce with the other. Now it is proper to pride and vainglory to seek one's own glory. And just as people are discordant when they hold to their own opinion in their hearts, so are they contentious when each defends his own opinion by words. Consequently contention is reckoned a daughter of vainglory for the same reason as discord.
