Each local congregation is fiercely independent and free to make it's own decisions. We strongly defend religious liberty, separation of church and state, and the priesthood of all believers. Such freedom inevitably results in variety. And variety results in controversy and conflict. If you want a religion where everybody believes the same thing, look somewhere besides Disciples.
Freedom creates diversity.
Diversity inevitably leads to controversy. Very few people enjoy dealing with controversial issues. Controversies make most religious folk nervous. Our natural tendency is to avoid controversy, but occasionally we cannot avoid dealing with difficult issues. And it may not be a bad thing for us to do at all.
