[29] In the Peace of Westphalia, 1648, the balance of power in Europe was recognised on the basis of terms such as these.

[30] Grotius, however, is a painstaking student of Scripture, and is willing to say something in favour of peace—not a permanent peace, that is to say, the idea of which would scarcely be likely to occur to anyone in the early years of the seventeenth century—but a plea for fewer, shorter wars. “If therefore,” he says, “a peace sufficiently safe can be had, it is not ill secured by the condonation of offenses, and damages, and expenses: especially among Christians, to whom the Lord has given his peace as his legacy. And so St. Paul, his best interpreter, exhorts us to live at peace with all men.... May God write these lessons—He who alone can—on the hearts of all those who have the affairs of Christendom in their hands.” (De Jure Belli et Pacis, III. Ch. XXV., Whewell’s translation.)

See also op. cit., II., Ch. XXIII., Sect. VIII., where Grotius recommends that Congresses of Christian Powers should be held with a view to the peaceful settlement of international differences.
