Make that a group of people and now you have a new religious sect/sects. This is how xianity/isalm/judaism split into different sects, calling the other sects not just misguided but evil, "Satanic" even. Egos dividing, differing and battling it out. Religion is but one dimension of this. Politics also has this.
Idk how Zevism will handle sectarianism. It's easy to remain unified while it's a small group with a single undisputed leadership, but as numbers grow it may become a challenge in the future. With Divine guidance this may be avoided entirely, but splits can happen for ethnic/political reasons too such as the Pagan groups split a long time ago, rather than religious disputes. Perhaps such kinds of splittings are natural and aren't meant to be stopped?
Maybe this has already happened? Not very familiar with the history. How many High Priest/Priestesses were there besides HPS Maxine and HP HoodedCobra, before HPS Lydia was promoted that is? From the different names I read on the site there were like 4/5 other Clergy members who then all left/were unfit for various reasons? I've also read the title meant far less back then.
