Here's one of the interesting changes that needs to happen to break past the '200 barrier':
In the small church approach to decision-making it is considered impossible to proceed with a change if any member if strongly opposed or especially if it appears that a change will actually result in some people leaving the church. 2) As a church nears the 200 barrier, there now is almost always someone who experiences a change as a loss. So 3) therefore no changes ever can occur unless many decisions that used to involved the whole membership shift to the leaders and staff.
