Here is what Paul wrote about the body of Christ as far as members in the body.

1Co 12:27 Now ye are the body of Christ, and members in particular. And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues.

In the 2x2 group it's like this: overseer, workers (men then women), elder, followers

There are three main branches of the doctrinally secretive sect. They are the 2x2s (main branch), Irvinites (followers of William Irvine) and Cooneyites (Followers or Edward Coooney).

2x2s

The 2x2s are the main branch in existence today in many countries of the world.

Irvinites

The Irvinites follow after William Irvine after he was excommunicated by the newly established oveseers back in the day. From what I understand, they are few in number and don't have workers.

Cooneyites

The Cooneyites were excommunicated from the 2x2 movement for believing in following the leading of a spirit in guiding their movements instead of being organized into fields with assigned workers.

Maybe they mean they don't have one name, they have many.? But it's mostly to be secretive and fly under the radar from authorities from what I gather.

The original cult was started by William Irvine. You can read about this in The Secret Sect book. Later, many broke off from the Irvinites as then new overseers gained power. This is the main 2x2 group. Also a group known as the Cooneyites formed around then. More recently a new movement within the 2x2s has started Excerpts.
