It's still a sect/cult no matter how small or sui generis. Their beliefs or practices are not even the same; it's a typical heterodox Protestant community centered around some Jewish practices mixed with a self-styled brand of Christianity.
Well, to begin with, how can you possibly have a heterodox Protestant community? I do agree though, that what we have could be tantamount to an ultra Pentecostal progression, taking elements of Christianity and Judaism, mixing them together and coming up with something unrecognizable to either.
