The faithful church expresses its commitment to the city—to the “inhabitants of the earth”—only in ways that are true to the gospel and to Christians’ identity as followers of the Lamb. This means that the church will above all serve, and that service will be Lamb-like, cruciform. It will neither sacralize nor seek secular power, whether economic, political, or military. It disavows, in other words, Christendom in favor of Christ.
