Ecclesiology is a key issue for the present age of church history. This groundbreaking work by one of today’s leading theologians offers a major Protestant ecclesiology for the church catholic. This volume, the first of three, considers the priesthood of the church in light of the priesthood of Christ. Tom Greggs shows the connection between Christ’s work as high priest and the universal church’s role in salvation. All together, the three volumes will offer a major statement on the doctrine of the church for Christians from a variety of backgrounds.
