Book excerpt: What is a church? This can be a difficult question to answer and Christians have offered a variety of perspectives. Gregg Allison thus explores and synthesizes all that Scripture affirms about the new covenant people of God, capturing a full picture of the biblical church. He covers the topics of the church's identity and characteristics; its growth through purity, unity, and discipline; its offices and leadership structures; its ordinances of baptism and the Lord's Supper; and its ministries. Here is a rich approach to ecclesiology consisting of sustained doctrinal reflection and wise, practical application. Part of the Foundations of Evangelical Theology series.
