Each community is governed by its own elders, chosen from among the men, and there is no denominational headquarters, no paid clergy, no seminary and no central treasury. Coordination happens through people moving — families are relocated between communities, sometimes between continents, on the elders' word. Women do not serve as elders and the community teaches distinct roles for men and women without apology. Around fifty communities exist in a dozen or so countries, with the largest concentrations in the United States, Germany, France, Spain and Brazil.
