This work investigates the complex intersection of Quaker theology and Enlightenment thought, specifically focusing on how the Society of Friends navigated the intellectual shifts of the eighteenth century. Madeleine Pennington, a scholar in the field of religious history, examines primary source documents and theological treatises to trace the evolution of Quaker identity. The book argues that Quakerism was not isolated from the broader philosophical currents of the era but rather engaged in a dynamic, often contentious, dialogue with Enlightenment rationalism and the changing understanding of Christology.

Scholars and historians of religion frequently note the academic rigor and depth of Pennington's research in this specialized area. Experts highlight this as a significant contribution to understanding the intellectual history of non-conformist religious groups during the Enlightenment.
