What was the fundamental source of justification for Bossuet's arguments about royal authority?

Bossuet was a bishop in the Catholic Church, and his arguments for royal authority were fundamentally based on his interpretation of the Bible. He wrote that "God...establishes kings." He pointed to the example of the house of David, established according to the Old Testament by God, which was hereditary in nature. From this fundamental belief, Basset argued that the authority of kings was beyond censure or question by ordinary people. Since kings were ordained by God, it was a sin to resist them. They owed nothing to any earthly authority and were responsible only to God. This is why the political philosophy Bossuet expressed is known as "divine right" theory. It was the intellectual basis of absolutism, especially in Bossuet's native France, where the Bourbon dynasty expressly claimed to rule by the authority of God, and to be the living embodiment of the French people themselves. Indeed, Bossuet occupied a very prominent place in the court of Louis XIV, the "Sun King" who best exemplified the ideal of divine right absolutism.
