I don't know a lot about them, have not known these people personally, merely studied them, but with sacred names stuff you find these newer Hebrew roots cult teachings. Like all cults, there's an underlying rabidness to other believers they believe are false believers. The JWs and SDAs will also call you devils and damned, behind your backs. But with Hebrew roots they always, from what I've seen, get down to this notion the Lord Jesus came to write the Torah on our hearts, though, duh, none of them can recite the begats or would know the first things about keeping the whole law. It's very Pharisaical, a cult that takes after those our Lord Jesus excoriated, but of even less and no known religion, of that vast category of legalists I call Jew-lites, who pick and choose laws to be under. Don't expect much sweetness and light, when the claws come out, of any adherents to fake gospels.
