Religion encompasses many forms of communication: between groups, within groups, and with God (or other deities). Such communication can be especially powerful when group members highly identify with their religious group and the beliefs therein. Equally, it can be divisive, as evidenced by religion-based intergroup conflict and intolerance (which often overlaps along ethnic or political lines). However, not all religious communication is verbal or explicit. Religious individuals also commonly transmit their beliefs, values, and identities through symbols, physical spaces, and music. Likewise, communication with God is often pursued with silent prayer, meditation, or ritual, which also serve to reinforce one’s spirituality alongside religious group boundaries. Taken together, these varying forms of communication have implications not only for religious intergroup relations (e.g., intergroup contact or conflict), but also for intragroup relations (e.g., the strengthening of social ties) and individual health outcomes (e.g., effective communication with health care providers and coping practices). Given the importance of religious identity for many individuals, the benefits for individual well-being and intragroup relations, and yet the intergroup strife that religious group divisions can incite, the ways in which we communicate our religious group identities deserve closer attention.
