Since the "Rod of Iron Ministries" (an offshoot from the Unification Church) was founded in 2017, its grown, established fringe political alliances, and incorporated in at least 2 more states.
It's also become more extreme. And, church leaders were at the Capitol on January 6.
Recently one member of the Rod of Iron Ministries, aka Sanctuary Church, was arrested for allegedly attacking an MTA vehicle, and had a "kill list' in his car.
He's facing federal charges. Ex-church members say that incident should be a warning for whats to come.

I think you're right when saying it isn't completely guided by religious ideological principles or the actual teaching/script. I do also think they will adopt or hijack a lot of Christian undertones, or just general religious/faith ideology. That is almost always present in cults or "sects" like this. There usually has to be a call to a higher power, whether it is a deity, God or a person themselves, they are typically key in this type of shit.
But the main guiding thing is a hatred of others, extreme paranoia and massive forms of what they believe is self preservation in the libertarian sense of huge selfishness
