Many congregations today are beset by fears, whether over loss of members and money, or of irrelevancy in an increasingly pluralistic society. To counter this, many congregations focus on strategy and purposewhat churches ‘;do’but Cheryl Peterson submits that mainline churches need to focus instead on ‘;what’ or ‘;who’ they areto reclaim a theological, rather than sociological, understanding of themselves.To do this, she places the questions of the church’s identity and mission into a conversation with the primary ecclesiological paradigms of the past century: the neo-Reformation concept of the church as a ‘;word event’ and the ecumenical paradigms of the church as ‘;communion.’ She argues that these two paradigms assume a context of cultural Christendom that no longer existsfocused on the church that is gatheredrather than the missional church that is sent out.
