Chapter 99: The Reform of Mexica Religion – Part 2

"Just above is the City Priest, responsible for a city and its nearby villages. The Priest of the Ecclesiastical Province, who is in charge of a complete region including several cities and villages. The establishment of an ecclesiastical province requires the approval of the central authority. The Priest of the Ecclesiastical Province can then be referred to as the High Priest, corresponding to specific states. Mexica with its Eleven States could then have eleven High Priests."

Several ecclesiastical provinces united form a general ecclesiastical province, and the priest in charge is the Supreme High Priest. If there is a significant important city, it can also be separately established as an equal-level Capital High Priest, to prevent the Supreme High Priest from becoming too powerful. Currently, it seems Mexica with its Eleven States can establish one General Ecclesiastical Province Supreme High Priest."
