Wouldn't that be nice. Unfortunately look at what happend with the Church of God - Armstrong people.
They divided into smaller sects and now they're a rainbow of different flavors and beliefs. Similarly the
Bible Student movement has several small but separate churches who loosely associate and have
conferences, but some don't get along with others, and refuse to exchange elders for talks etc.
The situation in Romania is interesting since there are several groups claiming to be the one true
Jehovah's Witnesses. Very similarly, if the WT were to fall, I'd see some going the way of Trinitarian
churches, others sticking by current beliefs, others reforming their beliefs with many along this wide
range of religious belief options... breaking apart and reassembling, sort of replicator style.
