In writing about this “Two Kingdoms Doctrine,” Erwin Mülhaupt explains that the “worldly kingdom,” while not Christ’s kingdom, is still a gracious gift from God. It is a sort of concession to the reality that the world after the Day of Pentecost but before the advent of “a new heaven and a new earth” is still, despite the presence of the Savior, a fallen and broken place.
The earthly kingdom has been instituted by God to limit the evil, chaos, and violence which would otherwise run amok on this earth.
The New Testament has a clear-eyed view of the present world: “not all have faith.” Even among those who have faith, who receive Jesus, sin still appears: “I do not do the good I want.” Because sin is present, God has instituted the kingdom of the world, to limit and restrain sin. Legislating restrictions against sin, and enforcing those boundaries, is the task of the worldly kingdom. As such, it is a negative kingdom, because, as Mülhaupt writes, one cannot command people to act out of love.
So God institutes this kingdom “of the left hand,” which operates by means of laws, regulations, legal systems, and ultimately by means of violence, in order to achieve a relative amount of humaneness, justice, and peace. It is clear that the “humaneness, justice, and peace” of the worldly kingdom is deficient, limited, and minimal. Yet it is still a grace, because without it, the earth would be flooded with evil.
The necessity of this arrangement arises from the fallen nature of human beings. When Luther crafted this doctrine, he was not under the illusion that people are good, and that evil resides only in the structures and organizations of the world.
A kingdom could be supplied with the best culture, civilization, and society; it could have the best economic, political, and governmental system; yet it would be plagued with the problems which all human society encounters, because its structures and organizations, however good they may be, are filled with human beings, and thereby filled with evil.
Erwin Mülhaupt writes:
Weil nie alle das Wort Gottes annehmen und weil der Glaube ‘nicht jedermanns Ding ist’ (2. Thess. 3,2) und weil man die Liebe nicht befehlen kann, darum ist es gut und nötig, daß es neben dem Reich Christi noch ein ‘Reich mit der linken Hand’ Gottes oder ein weltliches Regiment gibt, das mit Gesetz, Sitten, Ordnungen, Rechten und mit Gewalt wenigstens eine relative Menschlichkeit, Gerechtigkeit und relativen Frieden sichert und dem stets im Menschen lauernden Chaos wehrt; denn den Aberglauben, daß der Mensch gut sei und daß dsa Böse nur in den Strukturen und Ordnungen steckt, teilte Luther nicht.
Some people might think that Christians — or at least the really good Christians — wouldn’t need or want this worldly governance. A really good Christian would be acting with self-discipline and out of altruistic selflessness, always working for the good of his fellow man and for the good of his community.
This is a complete misunderstanding! Christians, even the best of them, are imperfect, flawed, and sinful, and don’t always do the right thing. All human beings are faced with, and need to face up to, the reality that they often do the wrong thing.
So Christians see the need for a worldly regime to keep civic order and promote peace. Christians see that they need this for themselves as guardrails to prevent themselves from running amok. They also see that this is good for the community as a whole, to promote more humane, just, and peaceful behavior from everyone, as Mülhaupt writes:
Ein Christ, der auf der Höhe des christlichen Glaubens und der christlichen Liebe steht, braucht das alles freilich nicht und ist nicht auf Gesetz, Sitte, Ordnung und Recht angewiesen, um das Richtige zu tun. Aber ersten gibt es hier auf dieser Erde diesen Christen gar nicht, der wirklich auf der Höhe des Glaubens und der Liebe steht, und zweitens gebietet die christliche Liebe, um des Nächsten willen alle Bemühungen des weltlichen Regiments um etwas mehr Menschlichkeit, Gerechtigkeit und Frieden zu unterstützen. Frage: ist solch nüchtern, aber dennoch positive Einschätzung und Unterstützung des weltlichen Regiments überholt oder nicht?
Mülhaupt poses a seemingly rhetorical question: Is Luther’s understanding of the two realms outdated? Have people changed? Has human nature changed, that we are so good now that we don’t need a worldly governance to maintain peace, justice, and humaneness?
