George Weigel, a Roman Catholic theologian, makes an interesting observation that I came across. He notes that the Christian notion of the kingdom of God and the eschaton are helpful to the exercise of civil virtue. If at the end of time, God will sweep away all the kingdoms of humanity, then any form of government or social order is merely provisional. One cannot make an idol out of any political order.
This is a helpful insight, especially for those within our society on either the left or the right who want to temporalize the eschaton. I also think this goes well with the Lutheran doctrine of the two kingdoms, which as Peter Berger observes, is radically anti-Utopian. Any civil order is simply the law's coercive measure to hold things together until they finally fall apart in the great apocalyptic break.
