In this final volume of a four-volume series, Michael Horton explores the origin, mission, and destiny of the church through the lens of covenantal theology. Arguing that the history of Israel and the covenant of grace provide the proper context for New Testament ecclesiology, Horton then shows how the church is constituted through the ascension of Christ, the Pentecost, and the Parousia and how it continues to live by the Word and sacraments. Horton's goal is to demonstrate the potential of a covenantal model for integrating the themes of the church as people and as place, with an urgent concern for contemporary practice.
