While these questions may seem innocuous, church has become conflicted territory recently, with internal factions, external pressures, and ecumenical turmoil all calling for a more positive, studier, more resilient notion of Christian community. Wengert approaches the questions as a Reformation historian. He shows how the New Testament notion of "marks" of the church was taken up by Luther and developed by Melanchthon not as descriptive tag but as a criterion for authenticity in Christian community. Lathrop, the liturgical theologian, shows concretely how those marks can stamp the worship life of a congregation as well as the evaluative work of congregations with their pastors, bishops, superintendents, and conference ministers. Only with a sturdy sense of their own identity--as a holy people, grounded in common practices and commitments--can Christian assemblies truly engage and even transform today's cultural context. This volume originated as six lectures jointly presented to the Academy of Bishops of the ELCA in 2001.
