In
American Christian Programmed Quaker Ecclesiology, Derek Brown argues that American Christian Programmed Quakerism has inherited a practical and pragmatic ecclesiology at the expense of an ontological understanding of the church. Inspired by the work of Gerben Heitink, Brown proposes a normative, deductive, ontological ecclesiology based on the biblical concept of
koinonia, which would act as a 'foundational' model for future confessional, empirical, and practical efforts. To help form the proposed ecclesiology, Brown explores the ecclesiological views of George Fox and Robert Barclay, the adoption of the pastoral system, and the emergence of the Evangelical Friends Church. The ecclesiological writings of Miroslav Volf, Wolfhart Pannenberg, Hans Küng, Jennifer Buck, and C. Wess Daniels are also surveyed.
