You can tell its not a cult, because they encourage their young people to go to local churches.
Wow. Really?
Cult: a system of religious veneration and devotion directed towards a particular figure or object.
do they encourage the young people to cut themselves off from their families?
Not necessary for being a cult.
do they encourage young people to give them large sums of money?
Not necessary for being a cult.
do they claim to have the only correct interpretation of scripture, which is somehow at odds with everyone elses?
I imagine they claim to have the only correct inturpretation. But even so, not necessary for being a cult.
do they encourage unquestioning loyalty to a charismatic leader?
Their leader would be God. So I expect so.
it's too easy to call something you disagree with a cult
It's too easy to dismiss something of being a cult when you're already engrained in the world view.
The word religion and the word cult have very similar definitions but for some reason, cult has negative connotations and religion does not. It's amazing how hard people will argue that their sect is not a cult when they think it's ok.
