"[...] In this small but important academic book, Madeleine Ward offers a theological reading of the Keithian controversy, which occurred in the American colonies and in England towards the end of the seventeenth century. It will be of interest to both historians of Restoration Quakerism and scholars of Quaker theology and doctrine [...] All this helps us to better understand the significant diversity of faith and practice that currently exists within global Quakerism. For these reasons, this work is highly recommended." - Stuart Masters, Woodbrooke Quaker Study Centre, in: Journal of the Friends Historical Society 70"[...] The Christian Quaker is an important and timely addition to the literature on both early Quakerism and early modern historical theology, which adds much to an emerging literature on Quaker theology. Ward ably fulfills her objective of showing that, in the seventeenth century, there was no contradiction between being a Christian and being a Quaker." - Michael B. Riordan, Edinburgh, in: Journal of the Ecclesiastical History 70.4 (2019)
