Politics per se are not the church’s business. The church is not to preoccupy itself with results. It has not even to practice “pacifism,” that is, reject arms with the object of stopping war. No, God expects only one thing of it: that it walk in obedience to the gospel, refusing violence in whatever form because of that obedience, without concerning itself with the consequences, good or bad, that such refusal may involve. Such faith puts into practice the justice that marks God’s kingdom. The church’s business is not to establish peace between the nations, but to bear witness to the love of God, to live in his peace and righteousness.
