Lactantius: The arms of the nations shall be burnt; and now there shall be no war, but peace and everlasting rest
From Divine Institutes
Translated by William Fletcher
For when God forbids us to kill, He not only prohibits us from open violence, which is not even allowed by the public laws, but He warns us against the commission of those things which are esteemed lawful among men. Thus it will be neither lawful for a just man to engage in warfare, since his warfare is justice itself, nor to accuse any one of a capital charge, because it makes no difference whether you put a man to death by word, or rather by the sword, since it is the act of putting to death itself which is prohibited. Therefore, with regard to this precept of God, there ought to be no exception at all; but that it is always unlawful to put to death a man, whom God willed to be a sacred animal.
Therefore, as the end of this world approaches, the condition of human affairs must undergo a change, and through the prevalence of wickedness become worse; so that now these times of ours, in which iniquity and impiety have increased even to the highest degree, may be judged happy and almost golden in comparison of that incurable evil. For righteousness will so decrease, and impiety, avarice, desire, and lust will so greatly increase, that if there shall then happen to be any good men, they will be a prey to the wicked, and will be harassed on all sides by the unrighteous; while the wicked alone will be in opulence, but the good will be afflicted in all calumnies and in want. All justice will be confounded, and the laws will be destroyed. No one will then have anything except that which has been gained or defended by the hand: boldness and violence will possess all things. There will be no faith among men, nor peace, nor kindness, nor shame, nor truth; and thus also there will be neither security, nor government, nor any rest from evils. For all the earth will be in a state of tumult; wars will everywhere rage; all nations will be in arms, and will oppose one another; neighbouring states will carry on conflicts with each other…Then the sword will traverse the world, mowing down everything, and laying low all things as a crop…For when Carthage was taken away, which was long its rival in power, it stretched out its hands by land and sea over the whole world, until, having subdued all kings and nations, when the materials for war now failed, it abused its strength, by which it destroyed itself.
Then for seven continuous years the woods shall be untouched, nor shall timber be cut from the mountains, but the arms of the nations shall be burnt; and now there shall be no war, but peace and everlasting rest. But when the thousand years shall be completed, the world shall be renewed by God, and the heavens shall be folded together, and the earth shall be changed, and God shall transform men into the similitude of angels, and they shall be white as snow…
