Grazer,
Here are a few quotes from the early Christians. This how they understood the teachings of Jesus and the Apostles.
Here are some quotes from some of the major writers of the period (prior to 325 A.D.). This changed after the church merged with the state and became corrupted. Prior to 325 A.D. you would be hard pressed to find a writer who says that Christians can use force of any kind.

Justin Martyr 160 AD.
we who formerly used to murder one another do not only now refrain from making war upon our enemies,

Justin Martyr
and we who were filled with war, and mutual slaughter, and every wickedness, have each through the whole earth changed our warlike weapons,—our swords into ploughshares, and our spears into implements of tillage,—and we cultivate piety, righteousness, philanthropy, faith, and hope, which we have from the Father Himself through Him who was crucified;

Tatian 160 AD.
How, then, shall I admit this nativity according to Fate, when I see such managers of Fate? I do not wish to be a king; I am not anxious to be rich; I decline military command;

Athenagoras 175 AD.
for we have learned, not only not to return blow for blow, nor to go to law with those who plunder and rob us, but to those who smite us on one side of the face to offer the other side also, and to those who take away our coat to give likewise our cloak. But, when we have surrendered our property, they plot against our very bodies and souls, pouring upon us wholesale charges of crimes of which we are guiltless even in thought, but which belong to these idle praters themselves, and to the whole tribe of those who are like them.

Irenaeus 180 AD.
the new covenant which brings back peace, and the law which gives life, has gone forth over the whole earth, as the prophets said: “For out of Zion shall go forth the law, and the word of the Lord from Jerusalem; and He shall rebuke many people; and they shall break down their swords into ploughshares, and their spears into pruning-hooks, and they shall no longer learn to fight.â€
The Early Church Fathers: Ante-Nicene Fathers Volume 1
Irenaeus
But if the law of liberty, that is, the word of God, preached by the apostles (who went forth from Jerusalem) throughout all the earth, caused such a change in the state of things, that these [nations] did form the swords and war-lances into ploughshares, and changed them into pruning-hooks for reaping the corn, [that is], into instruments used for peaceful purposes, and that they are now unaccustomed to fighting, but when smitten, offer also the other cheek, (Matt. 5:39)

Clement of Alexandria 195 AD.
For it is not in war, but in peace, that we are trained.

And an enemy must be aided, that he may not continue an enemy. For by help good feeling is compacted, and enmity dissolved.

Tertullian 197 AD.
If we are enjoined, then, to love our enemies, as I have remarked above, whom have we to hate? If injured, we are forbidden to retaliate, lest we become as bad ourselves: who can suffer injury at our hands?

Tertullian
Nay, He puts His interdict on every sort of man-killing by that one summary precept, “Thou shalt not kill.â€

Cyprian 250 AD.
Consider the roads blocked up by robbers, the seas beset with pirates, wars scattered all over the earth with the bloody horror of camps. 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.

Lanctantius 304-313 AD.
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: for they are ignorant of what this being serviceable is, who think nothing useful, nothing advantageous, but that which can be held by the hand; and this alone cannot be held, because it may be snatched away

Lanctantius
For it is not right that a worshipper of God should be injured by a worshipper of God.
