When therefore Christian kings are said to have spiritual dominion or supreme power in ecclesiastical affairs and causes, the meaning is, that within their own precincts and territories they have authority and power to command even in matters of Christian religion, and that there is no higher nor greater that can in those causes over-command them, where they are placed to reign as kings. But withal we must likewise note that their power is termed supremacy, as being the highest, not simply without exception of any thing.
