“We who were filled with war, and mutual slaughter, and every wickedness, have each through the whole earth changed our warlike weaponsâ€â€our swords into ploughshares, and our spears into implements of tillageâ€â€and we cultivate piety, righteousness, philanthropy, faith, and hope, which we have from the Father Himself through Him who was crucified.†– Justin Martyr (100-165 AD), Dialogue with Trypho 110

“But how will a Christian war, nay, how will he serve even in peace without a sword, which the Lord has taken away? For albeit soldiers had come unto John, and had received the formula of their rule; albeit, likewise, a centurion had believed, still the Lord afterward, in disarming Peter, unbelted every soldier.†– Tertullian (160-225 AD), On Idolatry 19
“Shall it be held lawful to make an occupation of the sword, when the Lord proclaims that he who uses the sword shall perish by the sword? And shall the son of peace take part in the battle when it does not become him even to sue at law? And shall he apply the chain, and the prison, and the torture, and the punishment, who is not the avenger even of his own wrongs?†– Tertullian (160-225 AD), The Chaplet 11

“And as we by our prayers vanquish all demons who stir up war, and lead to the violation of oaths, and disturb the peace, we in this way are much more helpful to the kings than those who go into the field to fight for them… And none fight better for the king than we do. We do not indeed fight under him, although he require it; but we fight on his behalf, forming a special army – an army of piety – by offering our prayers to God.†– Origen of Alexandria (185-254 AD), Against Celsus 8.73
“And to those who inquire of us whence we come, or who is our founder we reply that we are come, agreeably to the counsels of Jesus, to cut down our hostile and insolent wordy swords into ploughshares, and to convert into pruning-hooks the spears formerly employed in war.

“Therefore they are to be accounted as savage beasts who injure man; who, in opposition to every law and right of human nature, plunder, torture, slay, and banish.†– Lactantius of Bithynia (aprox 240-317 AD), Divine Institutes 6.10
“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.†– Lactantius of Bithynia (aprox 240-317 AD), Divine Institutes 6.20
“The whole world is wet with mutual blood; and murder, which in the case of an individual is admitted to be a crime, is called a virtue when it is committed wholesale. Impunity is claimed for the wicked deeds, not on the plea that they are guiltless, but because the cruelty is perpetrated on a grand scale.†– Cyprian of Carthage (250 AD), Epistle 1.6
“And this is at least incredible, inasmuch as even now those Barbarians who have an innate savagery of manners . . . and cannot endure to be a single hour without weapons; but when they hear the teaching of Christ, straightway instead of fighting they turn to husbandry, and instead of arming their hands with weapons they raise them in prayer, and in a word, in place of fighting among theselves henceforth they arm against the devil and against evil spirits, subduing these by self-restrains and virtue of soul. Now this is at once a proof of the divinity of the Saviour, since what men could not learn among idols they have learned from him.†– Athanasius of Alexandria (296-373 AD), On the Incarnation of the Word 52.2-4
