Forum:"Cult members" category

So I can't quite understand something. What is the narrative basis for category:cult members, category:cult leaders and category:cults in general? It seems to be a lot of stuff about Romans, but were are we getting the word "cult" from? Feels like that isn't canonical somehow, but a modern interpretation of religious views we find outdated today.

Anybody got, to coin a religious phrase, chapter and verse on the DWU usage of the word "cult"? 00:48:29 Mon 15 Aug 2011
