What is church? In the social sciences, church is ordinarily conceptualized as a physical gathering place where religious people go for worship and fellowship. Church is sacred; it is not secular. With this idea of church in mind, sociologists find that U.S. Christian youth (particularly young white men) are dropping out of church. Some are dropping out because they have lost faith in God. Others, however, are leaving church because they feel alienated from organized religion, not because they stopped being Christians. This rise in “unchurched believers” raises a question: how are Christian youth creating and expressing church beyond the confines of a religious institution?
