I don't know why they call it a church.
I guess if they would admit that this tech is actually curing all kind of mental and health problems incl. deadly diseases like
cancer THEN the whole medical establishment
would come against them.
So they make it a church and a sacrament which one receives.
I don't think it is a cult. No cult leaders,
no indoctrination. You can buy that service
or leave it. Once you bought it, you can renew it or not. There are no gatherings, no
cult magazine etc....
If you would like more information then read the "novel".
