Well... no.
Where you find the splits tend to be in Churches who tend to follow more closely the Roman Catholic tradition of the leaders telling the assembly what they are going to believe. In both cases the clergy tends to be much more liberal about everything then the laity. Which is why you find "democratic" (assembly vote) and "republican" (pastoral vote but churches have elected their pastor) Churches tend to be much more conservative. Where you find church splits in those cases is generally in the realm of personality and fellowship rather then doctrine. Which means that you can have Churches that believe basically the same doctrine with minor variations (women wear a covering in church vs they don't or men may play on non church sports team vs they may not).
But in these Churches you usually (there are exceptions) find very conservative beliefs.
Can you tell me who these churches are that follow the process that you laid out. The ELCA, Episcopalians, Methodist, Presbyterians and even most Baptist don’t follow those procedures.
