The Westminster Assembly is celebrated for its doctrinal standards and debates on church polity. But how often is the assembly noted for its extraordinary intervention in the pulpit ministry of the Church of England? In God’s Ambassadors, Chad Van Dixhoorn recounts the Puritan quest for a reformation in preachers and preaching and how the Westminster Assembly fit into that movement. He examines the assembly’s reform efforts, tracing debates and exploring key documents about preaching in a way that both highlights disagreements within the assembly’s ranks and showcases their collective plan for the church going forward. Moreover, Van Dixhoorn reveals the rationale behind the assembly’s writings and reforms, both in terms of biblical exegesis and practical theology. Unlike any other book, God’s Ambassadors draws attention to the lengths to which the Westminster Assembly would go in promoting godly preachers and improved preaching.
