Defender,
You wrote: I simply stated that based on biblical precedent, [early] Christians were not involved in national conflicts for the simple reason that their kingdom is not of this world. ...There is practically no difference between the aggression that ancient Rome manifested towards all that opposed it and the one that Hitler showed to his neighbors in WWII. And therefore, there should be no difference in the stand that early Christians took then from Christians who lived in nations that were in Hitler's sight.
It is true that when we review the records of the early church fathers up to about 170 A.D., no mention is made of Christians being enrolled in the military. However, the fact is that none of the earliest writers, such as Polycarp (A.D. 70-155) mention anything for or against military service. The writings of St. Clement (A.D. 30-100), Mathetes (A.D. 130), Ignatius (A.D. 30-107), Papias (A.D. 70-155), Justin Martyr (A.D. 110-165), the epistles of Barnabus (A.D. 100), Ireneas (A.D. 120-202), the Shepherd of Hermas (A.D. 160), Tatian (A.D. 110-172), Athenagoras (A.D. 177), and Clement of Alexandria (A.D. 153-217) do not discuss whether it is right or wrong for Christians to be involved in war. However, it is worthwhile to note that Clement of Alexandria wrote, "Sail the sea, you who are devoted to navigation, yet call the whilst on the heavenly pilot. Has (saving) knowledge taken hold of you while engaged in military service? Listen to the commander who orders what is right." (Ante-Nicene Fathers, Vol. II, p. 200) This punches a hole in the belief of some that all those in the military who became Christians in the first two hundred years after Christ immediately left the military.
It is also a fact that no mention is made up until the time of Tertullian (A.D. 145-220) that any Christian believed it was wrong to serve in the military.
Your saying that Christians today really have no reason to view serving in the military any differently than early Christians viewed serving in the Roman army is false for at least two reasons. First of all is the fact that Rome often persecuted Christians and often used its military personel to do so. This situation certainly strongly discouraged - to put it mildly - Christians from becoming Roman soldiers. The Roman government also required all soldiers to take an oath of allegiance to the emperor. This oath included words which acknowledged the Roman emperor as their God. Of course, no Christian could do such a thing, then or now. These things obviously had an awful lot to do with the fact that early Christians did not enlist in the Roman army.
You seem to believe that the apostolic period began with pure pacifism, continuing until the time of Constantine. And that during Constantine's time when the church became "apostate" Christains began joining the military. You do not seem to consider the difference in circumstances that had come about by Constantine's time. Christians were no longer being persecuted by the Romans. Christians no longer had to worship the emperor in order to join the military. Serving in the military was no longer an issue of idolatry for the Christian, and so many joined.
You wrote: In your analogy, the Samaritan should not have only offered HUMANITARIAN assistance to the one in need, but that he should also have pusued the robbers and beat them into submission, even killing them if he had to in order to protect the neighborhood from their menace.
Of course he should not have. And neither should we under similar conditions. We should report muggers to the police if we know their identities. Then, if Christians are employed in our communities on the police force, they will track the muggers down and arrest them. And they will use force to do so, if such force is necessary, to protect us from such men.
You wrote: In your view, it is ok to kill someone just because he is greedy and not allowing food to be rationed out to those in need.
In my view if armed men are using force to prevent food and medicine from being delivered to starving and sick people, such as was happening in Somolia, those men should be ordered to surrender or be shot. What if your childen were dying and needed medicine and someone stood in your doorway preventing you from bringing it to them, what would you do? Would you use force to remove them if they refused to let you reach your children, or would you let your children die. If you say you would use such force, why then is it wrong to do the same to save your neighbor's children?
You wrote: Sincere Christians walk by the spirit and are focused on things above and not on things on earth and follow the lamb wherever he goes and truly consider that their kingdom IS NOT OF THIS WORLD.
Jesus said that his kingdom was no part of this world; otherwise his servants would fight that he not be delivered up to the Jews (John 18:36). Jesus made it plain that the real hope of believers was in the future literal kingdom of God, to be established on the earth (at his return). He continually emphasized this to his followers, who erroneously believed they would somehow bring about the existence of the kingdom through physical force or revolution (Acts 1:6). Did this mean that Jesus was always opposed to the use of force to defend what is right in this world? No, it does not. For Jesus himself did not hesitate to use aggressive force in clearing out the temple area of the moneychangers (Matt. 21:12; John 2:15). By his use of a whip of cords Jesus clearly showed that he condoned the just use of force.
In his discussion about not paying back evil for evil and the taking of vengeance, Paul says, "If possible, so far as it depends on you, be at peace with all men." (Romans 12:18) If there is something we can do to ward off arguments or violence with others, then we are to seek this foremost. This does not mean, however, that we are to consistently allow evil people to use us for their own ends (Prov. 25:26). If we are aware of evil intentions on their part that will bring harm to others, we would not logically seek "peace" by giving in to their demands. You do not turn over your child to a child molester just to "keep peace." By the same token, many Christians feel that the Free World is not to disarm so that totalitarian countries can take over and destroy the lives of millions. They see it as the same kind of issue, one of self-defense. Peace isn't always maintained by giving in to deliberate evil. Is it really a manifestation of goodness to furnish no opposition to evil? I don't think so.
