The Church in Act explores the dynamics of ecclesial and liturgical theology, examining the body of Christ in action. Maxwell E. Johnson, one of the premier liturgical specialists in the field, provides in this volume historical and doctrinal thinking on a diversity of liturgical subjects under the umbrella of Lutheran liturgical theology and in ecumenical conversation. The topics under consideration range from baptismal spirituality to Eucharistic concerns, including real presence, pneumatology, and reservation; discussions on what constitutes liturgical normativity, the diverse hermeneutical approaches to the Revised Common Lectionary, and the place of Mary in ecumenical dialogue and culture (especially Latino-Hispanic); issues of full communion based on a liturgical reading of the Augsburg Confession VII; and specific questions related to liturgy and ecumenism today in light of recent translation changes in Roman Catholic practice. Together, the volume offers a robust account of the liturgical, sacramental, and spiritual practices of the church for scholars, students, pastors, and others who seek to minister in an ecumenical context with increased understanding and insight.
