Novel communities are often based around beliefs before those beliefs have been properly embedded in their practices. As a result, such communities tend to come across as kooky and illegitimate.
It would be important for practice to lead belief in the process of transformation from the prevailing social order to a biblical utopia. So long as the practices are well understood, the belief systems needn't be emphasized. It's not how we couch the beliefs that counts, it's how we couch the values and virtues that support those beliefs.
