No offence, but is English your first language? This sounds entirely unrelated to the concept of a cult. I think you're just describing a company, an LLP with a religious focus.
Hearing about a group of people who have successfully implemented small scale communism with a religion involved and they thrived for over 100 years isn't something you want to shout from the rooftops as it would encourage more of this behavior.
In contemporary English, cult refers specifically to brainwashy abusive practices that attempt to control every aspect of the person's life and tend not to allow you to leave.
Some groups like the Amish and the ultra-Orthodox Jews in North America live in insular communal societies, but most would not describe them as cults. (Though sometimes the more isolationist groups do get called so, maybe with some cause.)
