I.—In the last lecture I said that justice would seem to be the typical virtue of the State, as holiness of the Church. Let us, then, first consider this virtue of justice in the light of our Lord’s teaching concerning one of the most familiar aspects of justice—its penal aspect.
Those sayings that have of late given rise to so many searchings of heart among Christians—the sayings about turning the other cheek and the rest—are given by our Lord as explanations of the saying that He came "not to destroy the law but to fulfil it." The words "to fulfil" of course mean not only to obey and carry out, but to complete.
In what sense is this teaching of our Lord the completion of the law? For the law of Moses, like every other law, was concerned with regulating the relations of men to one another, as well as their duties towards God; and it enforced what it enjoined by penalties.
At first sight no doubt it looks as if He were directly contradicting what had been said to them of old time—
"Ye have heard that it was said, An eye for an eye, and a tooth for a tooth: but I say unto you, That ye resist not him that is evil; but whosoever smites thee on thy right cheek, turn to him the other also, and if any man will sue thee at the law, and take away thy coat, let him have thy cloak also."
How is this the fulfilment or completion of the Mosaic or any other law? At this distance of time, it is hard to remember what was the original significance of the law of retaliation. We are inclined to think that the words "an eye for an eye and a tooth for a tooth" are intended to give a licence to that degree of vindictiveness; but on the contrary, in the primitive stage in which that enactment was given, it was not a licence given to man’s instinct for vengeance, but a limitation set upon that primitive and animal instinct, whose natural tendency, if unchecked, is to take two eyes for an eye and a set of teeth for a tooth. The _lex talionis_ said—Only an eye for an eye, and only a tooth for a tooth.
Our Lord carries the same principle further; not even that degree of vindictiveness is allowed. The first necessity was to put bounds upon man’s natural and almost insatiable lust for vengeance. The next was to tell him that the whole method of vengeance could never succeed in what is its only really justifiable aim. For what is the true function of the law, whether that of Moses or any other? It is always two-fold; it must always aim not merely at checking the evil act, but at converting, if possible, the evil will.
