Who, then, has done these things? Who has united in peace those who hated one another, if not the beloved Son of the Father, the common Savior of all, Jesus Christ, who in His love endured everything for our salvation? This peace that He would establish had also been prophesied long before, for Scripture says, "They shall beat their swords into plowshares and their spears into sickles, and nation shall not take up sword against nation, nor shall they learn war anymore."
Nor is this by any means incredible. The barbarians of the present day are naturally savage in their habits, and as long as they sacrifice to their idols they rage furiously against each other and cannot bear to be a single hour without weapons.
But when they hear the teaching of Christ, they immediately turn from war to farming; instead of arming their hands with swords, they stretch them out in prayer. In short, instead of fighting one another, they now arm themselves against the devil and the demons, fighting them with self-control and virtue of soul.
This is a sign of the Savior's divinity: what people could not learn from idols, they have learned from Him. It is also no small proof of the weakness and worthlessness of demons and idols. Knowing their own weakness, the demons formerly set people at war against one another so that they would not stop their mutual strife and turn to fight the demons.
Indeed, instead of fighting one another, the disciples of Christ array themselves against demons through their way of life and deeds of virtue. They drive them away and mock their leader, the devil. Thus in youth they practice self-control; in trials they endure; in hardships they persevere. When insulted they bear it; when deprived of possessions they scorn the loss. Most remarkably, they even scorn death and become martyrs of Christ.
