The Divine Right of Kings is a modern phenomenon, mostly the 1700s IIRC, which is post-feudal (except in Russia, which was progressing into feudalism at the time). It continued into the 1900s in many places, in somewhat modified form.
If the King has all power, then a constitution, if granted, is limits on the royal power and prerogatives, and the government may do anything not forbidden to it. If the government is formed with a constitution as a charter, the government may only do what is allowed.
