I would suggest reading the article first. Monarchy isn’t theocracy. The Spanish Inquisition in particular was a power grab by the crown in a time when “two swords” feudalism was giving way to absolute secular monarchy, even in Catholic countries. The (partial) motivation in rooting out heresy was done in a belief that false teaching was dangerous for ignorant people, not to earn God’s approval for the ruler or the country. Grouping actions, circumstances, motivations and outcomes this disparate into a more precise term like “ritual” only creates a need for a new word.
