From all this evidence it is manifest that the Roman people prevailed when all were striving to gain the Empire of the world. Therefore it was by the judgment of God that it prevailed; consequently its Empire was gained by the judgment of God, which is to say, that it was gained by right.
X.--And what is gained as the result of single combat or duel is gained of right. For whenever human judgment fails, either because it is involved in the clouds of ignorance, or because it has not the assistance of a judge, then, lest justice should be left deserted, we must have recourse to Him who loved justice so much that He died to fulfil what it required by shedding His own blood. Therefore the Psalmist wrote: "The righteous Lord loveth righteousness." This result is gained when, by the free consent of the parties, not from hatred but from love of justice, men inquire of the judgment of God by a trial of strength as well of soul as of body. And this trial of strength is called a duel, because in the first instance it was between two combatants, man to man.
But when two nations quarrel they are bound to try in every possible way to arrange the quarrel by means of discussion; it is only when this is hopeless that they may declare war. Cicero and Vegetius agree on this point, the former in his De Officiis,[266] the latter in his book on war. In the practice of medicine recourse may only be had to amputation and cauterising when every other means of cure have been tried. So in the same way, it is only when we have sought in vain for all other modes of deciding a quarrel that we may resort to the remedy of a single combat, forced thereto by a necessity of justice.
[Footnote 266: De Off. i. 12; De Re Milit. iii. prol.--(W.)]
Two formal rules, then, of the single combat are clear, one which we have just mentioned, the other, which we touched on before, that the combatants or champions must enter the lists by common consent, not animated by private hatred or love, but simply by an eager desire for justice. Therefore Cicero, in touching on this matter, spoke well when he said: "Wars, which are waged for the crown of empire, must be waged without bitterness."[267]
[Footnote 267: "Imperii gloria," not "corona," in Cic. de Off. i. 12.--(W.)]
But, if the rules of single combat be kept when men are driven by justice to meet together by common consent, in their zeal for justice (and if they are not, the contest ceases to be a single combat), do not they meet together in the name of God? And if it is so, is not God in the midst of them, for He Himself promises us this in the Gospel? And if God is there, is it not impious to suppose that justice can fail?--that justice which He loved so much, as we have just seen. And if single combat cannot fail to secure justice, is not what is gained in single combat gained as of right?
