Let us now ask those who reject the law, “is, ‘Be not angry’ contrary to ‘Do no murder’? or is not the one commandment the completion and the development of the other?” Clearly the one is the fulfilling of the other, and that is greater on this very account. Since he who is not stirred up to anger, will much more refrain from murder; and he who bridles wrath will much more keep his hands to himself. For wrath is the root of murder. And you see that He who cuts up the root will much more remove the branches; or rather, will not permit them so much as to shoot out at all. Not therefore to abolish the law did He make these enactments, but for the more complete observation of it. For with what design did the law enjoin these things? Was it not, that no one might slay his neighbor? It follows, that he who was opposing the law would have to enjoin murder. For to murder, were the contrary to doing no murder. But if He doth not suffer one even to be angry, the mind of the law is established by Him more completely. For he that studies to avoid murder will not refrain from it equally with him that hath put away even anger; this latter being further removed from the crime.
