Hyppolytus 170 – 235 A.D.
“Do not avenge yourself on those who injure you…let us imitate the Lord, who when he was reviled, reviled not again; when he was crucified, he answered not; when he suffered, he threatened not; but prayed for his enemies.”“Nothing is better than peace, by which all war of those in heaven and those on earth is abolished.”
Tertullian 160 – 220 A.D.
“For what difference is there between provoker and provoked? The only difference is that the former was the first to do evil, but the latter did evil afterwards. Each one stands condemned in the eyes of the Lord for hurting a man. For God both prohibits and condemns every wickedness. In evil doing, there is no account taken of the order… the commandment is absolute: evil is not to be repaid with evil.”
“Under no circumstances should a true Christian draw the sword.” – ibid
Justin Martyr 160 A.D
We who formerly used to murder one another do not only now refrain from making war upon our enemies, but also, that we may not lie nor deceive our examiners, willingly die confessing Christ.
“Christians have changed their swords and their lances into instruments of peace, and they know not now how to fight.” – ibid
Cyprian 200–258 A.D.[Christians] are not allowed to kill, but they must be ready to be put to death themselves… it is not permitted the guiltless to put even the guilty to death.” “God wished iron to be used for the cultivation of the earth, and therefore it should not be used to take human life.
Origen 185–254 A.D.
Christians could never slay their enemies. For the more that kings, rulers, and peoples have persecuted them everywhere, the more Christians have increased in number and grown in strength.
Athenagoras 177 A.D.
“Our prayers defeat all demons who stir up war. Those demons also lead persons to violate their oaths and to disturb the peace.
Commodianus 250 A.D.
“Make thyself a peace-maker to all men.”
Clement of Alexandria 150-215 A.D.
For we do not train our women like Amazons to manliness in war; since we wish the men even to be peaceable.
The Christian poor are “an army without weapons, without war, without bloodshed, without anger, without defilement.” – ibid
For He says, “Take no anxious thought for tomorrow,” meaning that the man who has devoted himself to Christ ought to be sufficient to himself, and servant to himself, and moreover lead a life which provides for each day by itself. For it is not in war, but in peace, that we are trained.War needs great preparation, and luxury craves profusion; but peace and love, simple and quiet sisters, require no arms nor excessive preparation. The Word is their sustenance. – ibid
And so, in this commandment of God, no exception at all ought to be made to the rule that it is always wrong to kill a man, whom God has wished to be regarded as a sacrosanct creature.”“When we suffer such ungodly things, we do not resist even in word. Rather, we leave vengeance to God.”“The Christian does injury to no one. He does not desire the property of others. In fact, he does not even defend his own property if it is taken from him by violence. For he knows how to patiently bear an injury inflicted upon him.”“When God forbids us to kill, he not only prohibits us from open violence… 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… 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.”“We do not resist those who injure us, for we must yield to them.”“When men command us to act in opposition to the law of God, and in opposition to justice, we should not be deterred by any threats or punishments that come upon us. For we prefer the commandments of God to the commandments of man.”“Someone will say here: ‘What therefore, or where, or of what sort is piety?’ Assuredly it is among those who are ignorant of war, who keep concord with all, who are friends even to their enemies, who love all men as their brothers, who know how to restrain their anger, and to soothe all madness of mind by quiet control.”“God might have bestowed upon his people both riches and kingdoms, as he had given previously to the Jews, whose successors and posterity we are. However, he would have Christians live under the power and government of others, lest they should become corrupted by the happiness and prosperity, slide into luxury, and eventually despise the commandments of God. For this is what our ancestors did.”“Why should the just man wage war, and mix himself up in other people’s passions – he in whose mind dwells perpetual peace with men?” – ibid
Tarachus 304 A.D.
“Christians are not allowed to use violence to correct the delinquencies of sins.”“Man is in reality a pacific instrument.”“The followers of peace use none of the implements of war.”“We have made use of only one instrument, the peaceful word, with which we do honor to God.”“We are being educated, not in war, but in peace.”“We are the race given over to peace.”“[Christians] are an army without weapons, without war, without bloodshed, without anger, without defilement.”
Lactantius 240 -320 A.D.
For how can a man be just who injures, who hates, who despoils, who puts to death? And they who strive to be serviceable to their country do all these things…Whoever, then, has gained for his country these goods – as they themselves call them – that is, who by the overthrow of cities and the destruction of nations has filled the treasury with money, has taken lands and enriched his country-men – he is extolled with praises to the heaven: in him there is said to be the greatest and perfect virtue. And this is the error not only of the people and the ignorant, but also of philosophers…Therefore, when they are speaking of the duties relating to warfare, all that discourse is accommodated neither to justice nor to true virtue, but to this life and to civil institutions.- (A.D. 303-313)
The Didache 50 A.D.
And of these sayings the teaching is this: Bless those who curse you, and pray for your enemies, and fast for those who persecute you. For what reward is there for loving those who love you? Do not the Gentiles do the same? But love those who hate you, and you shall not have an enemy. Abstain from fleshly and worldly lusts. If someone strikes your right cheek, turn to him the other also, and you shall be perfect. (A.D. 80) ch. 1
Theophilus of Antioch 180 A.D.
“Say to those that hate and curse you, you are our brothers!”
Athanasius 296 AD – 373 A.D.
“Christians, instead of arming themselves with swords, extend their hands in prayer.”
