I will say this is the first time I've ever heard the term "TWIS" - The Way International Structure. This seems to be a new acronym and term that this woman has made up.
To me it is TWISted.
I mean I'm a part of the body of Christ, as are the church-going folks in my neighborhood, city, community, on TV, etc. So are TWI members. They are the elevated nose of the body of Christ. Oh wait, Christ didn't elevate his nose.
So functionally, these people are starting a church, in their own home, with a Way brain, a Way background, and probably mostly Way materials. Anyone can come! Will anyone? Well, let's see. When you called it a twig and were still accepted in the Way, did anyone come then? Not really? OK. Well that's kind of a really good indicator there.
The state of TWIS.
BTW I've known of old Corpse grads who did this right after the fog years. Then they had a family Bible fellowship for 20 years. A couple outside people came for a while. I mean with this approach and home schooling, you could live completely off the grid like the Unabomber. Not real sure what this has to do with Christianity though.
