I hope you understand, then, fathers, that to avoid the crime of murder, we must act at once by the authority of God, and according to the justice of God; and that when these two conditions are not united, sin is contracted; whether it be by taking away life with his authority, but without his justice; or by taking it away with justice, but without his authority. From this indispensable connection it follows, according to St. Augustine, “that he who, without proper authority, kills a criminal, becomes a criminal himself, chiefly for this reason, that he usurps an authority which God has not given him;” and on the other hand, magistrates, though they possess this authority, are nevertheless chargeable with murder, if, contrary to the laws which they are bound to follow, they inflict death on an innocent man. Such are the principles of public safety and tranquillity which have been admitted at all times and in all places, and on the basis of which all legislators, sacred and profane, from the beginning of the world, have founded their laws. Even Heathens have never ventured to make an exception to this rule, unless in cases where there was no other way of escaping the loss of chastity or life, when they conceived, as Cicero tells us, “that the law itself seemed to put its weapons into the hands of those who were placed in such an emergency.” But with this single exception, which has nothing to do with my present purpose, that such a law was ever enacted, authorizing or tolerating, as you have done, the practice of putting a man to death, to atone for an insult, or to avoid the loss of honor or property, where life is not in danger at the same time; that, fathers, is what I deny was ever done, even by infidels. They have, on the contrary, most expressly forbidden the practice. The law of the Twelve Tables of Rome bore, “that it is unlawful to kill a robber in the day-time, when he does not defend himself with arms;” which, indeed, had been prohibited long before in the 22d chapter of Exodus. And the law _Furem_, in the _Lex Cornelia_, which is borrowed from Ulpian, forbids the killing of robbers even by night, if they do not put us in danger of our lives.[256]
