Letter 138: 1. In writing to the illustrious and most eloquent Volusianus, whom we both sincerely love, I thought it right to confine myself to answering the questions which he thought proper himself to state; but as to the questions which you have submitted to me in your letter for discussion and solution, as suggested or proposed either by Volusianus hims...

Augustine to Marcellinus, greetings.

You have asked me to address, at greater length, the objection raised by Volusian's circle about the compatibility of Christian teaching with the duties of the state. I do so gladly, because this is perhaps the most important practical question facing the Church in our time.

The charge is this: Christ's teaching — love your enemies, turn the other cheek, do not resist evil — makes good men into bad citizens. An empire of Christians would be defenseless, because its people would refuse to fight.

The charge is wrong, and I will show you why.

First: Christ's commands about non-resistance apply to the disposition of the heart, not to every conceivable external action. "Turn the other cheek" means: do not harbor a spirit of revenge. It does not mean: let your neighbor's children be murdered while you stand by practicing inner serenity. The father who defends his family from a murderer is not violating Christ's teaching — he is fulfilling his God-given duty to protect the innocent. And what the father does for his family, the magistrate does for the city, and the emperor does for the empire.

Second: war itself is not always a sin. It is always a tragedy, always a sign of human failure, always something to be mourned. But when a just cause exists — the defense of the innocent, the punishment of wicked aggression, the restoration of a violated peace — then the use of force, conducted by lawful authority, is not forbidden but permitted by the very God who commands us to love our enemies.

For consider: love for your enemy does not mean allowing your enemy to destroy the innocent. In fact, true love for an unjust aggressor sometimes requires stopping him — because allowing him to continue his injustice harms his own soul as well as his victims' bodies. The ruler who restrains the wicked man by force may be doing the wicked man the greatest possible service — by preventing him from committing further sins that will weigh against him at the judgment.

Third: the virtues Christ commands — patience, mercy, forgiveness, humility — are not alternatives to justice. They are its companions. The just ruler is patient before he punishes. He is merciful in his sentencing. He forgives personal insults while still holding the line on public order. He is humble enough to recognize that his authority comes from God and not from himself.

The Roman Empire was not weakened by Christianity. It was strengthened by it — because Christianity gave Rome something it had always lacked: a basis for justice that did not rest on mere power. The old Roman virtues — courage, discipline, loyalty — were admirable but incomplete. Without the foundation of divine justice, they could be used for tyranny as easily as for liberty. Christianity completes the Roman virtues by grounding them in the will of God.

Tell Volusian: the faith he fears would ruin the state is the only thing that can give the state a reason to exist.

Farewell, brother.

[Context: This letter, together with Letters 133 and 137, forms Augustine's response to the intellectual circle around Volusian, a Roman senator. The discussion — conducted through the intermediary Marcellinus — represents one of the most sophisticated pagan-Christian dialogues of late antiquity. Augustine's argument about the compatibility of Christianity with statecraft, including his careful distinction between personal non-resistance and the legitimate use of force by public authority, became the foundation for the Western "just war" tradition that shaped medieval and modern political thought.]
