When sovereignty belongs to God, are rulers more limited or less?
Hebrew and Arabic, the two languages I work between, carry traditions that both, at various points, said that sovereignty ultimately belongs to God. I've noticed that the same premise has been used to reach opposite conclusions.
In 1 Samuel 8 the people ask Samuel for a king "like all the nations". Samuel is displeased, and God tells him that it is not Samuel they have rejected, but God himself. Samuel then warns them what a king will take from them: their sons, their daughters, their fields. Here divine sovereignty is a check: human kingship is a concession, viewed with suspicion. Deuteronomy's law of the king makes the same point by limiting what the king may accumulate and requiring him to keep a copy of the law.
Al-Mawardi, as I understand from a reading group here, treats the caliph's authority as delegated and conditional, which also sounds like a limit.
But "divine right" has also been used the other way: James VI of Scotland, in The True Law of Free Monarchies (1598), argued that kings answer to God alone and not to their subjects. There, God's sovereignty shields the ruler from everyone else.
So, an open question: does locating sovereignty in God tend to limit rulers, or to empower them? Or does it depend entirely on who gets to say what God requires?
