The organization of the churches allowed for divisions, but there was an intended unity among them. They were all to preach the same gospel even while operating more locally. It is unclear whether the seven churches in the land of Zarahemla correspond to the municipalities or not. It is tempting to suggest that there was a church in each separate city, thus suggesting that there were seven cities beholding to the Nephite hegemony. There could have been several smaller communities that each surrounded and that looked to a particular larger city as their center for political structure, religion, and perhaps, more importantly, their market.
Mormon ends the discussion of the creation of churches with the typical indication that they were blessed and prospered.
