“If a religious community lacks cohesion, it will lose members. But other problems—from isolation to aggression—arise when a religious community is too cohesive, when it is so tightly bound there is no space for adhesive forces to form ties with the wider culture and members of other communities. When inward-looking groups face outward with fear or fury, they can become, to coin a term, dehisive, a bond-breaking social force. The history of religion provides myriad examples of volatile religious movements that overemphasized in-group solidarity and escalated tensions with outsiders.” CohesionReligious Community Book:Religion: A Very Short Introduction Source: Religion: A Very Short Introduction
