I'm not personally advocating for the pacifistic point of view, but I am aware that there are several sayings from the Early Church Fathers which CAN be used to support such a viewpoint. Since y'all are asking for evidence, here is some:Saint Justin Martyr:
“The devil is the author of all war.” “We, who used to kill one another, do not make war on our enemies. We refuse to tell lies or deceive our inquisitors; we prefer to die acknowledging Christ.” Tertullian:
“But now inquiry is being made concerning these issues. First, can any believer enlist in the military? Second, can any soldier, even those of the rank and file or lesser grades who neither engage in pagan sacrifices nor capital punishment, be admitted into the church? No on both counts—for there is no agreement between the divine sacrament and the human sacrament, the standard of Christ and the standard of the devil, the camp of light and the camp of darkness. One soul cannot serve two masters—God and Caesar…But how will a Christian engage in war—indeed, how will a Christian even engage in military service during peacetime—without the sword, which the Lord has taken away? For although soldiers had approached John to receive instructions and a centurion believed, this does not change the fact that afterward, the Lord, by disarming Peter, disarmed every soldier.”
“Under no circumstances should a true Christian draw the sword.” Hippolytus of Rome:
"“A soldier, being inferior in rank to God, must not kill anyone. If ordered to, he must not carry out the order, nor may he take an oath (sacramentum) to do so. If he does not accept this, let him be dismissed from the church. Anyone bearing the power of the sword, or any city magistrate, who wears purple, let him cease from wearing it at once or be dismissed from the church. Any catechumen or believer who wishes to become a soldier must be dismissed from the church because they have despised God.”Saint Irenaeus:
"“Christians have changed their swords and their lances into instruments of peace, and they know not now how to fight.” Saint Cyprian:
[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.
The source from which I draw these is, regrettably, this blog:http://rogueminister.wordpress.com/2008/11/19/quotes-the-early-church-on-war-and-violence/
All it took was a simple Google search to find this. There are many more quotes from that blog which supports some kind of view of pacifism.
Ignoring the source and just taking the quotes for what they are, we at least now have evidence for a pacifistic argument.
