What are the roles of canon and community in the understanding and articulation of Christian doctrine? Should the church be the doctrinal arbiter in the twenty-first century? In John Peckham tackles this complex, ongoing discussion by shedding light on issues surrounding the biblical canon and the role of the community for theology and practice. Peckham examines the nature of the biblical canon, the proper relationship of Scripture and tradition, and the interpretation and application of Scripture for theology. He lays out a compelling canonical approach to systematic theology -- including an explanation of his method, a step-by-step account of how to practice it, and an example of what theology derived from this canonical approach looks like.
