This book reflects and comprises the latest in research on the history and theology of Reformed Orthodoxy (± 1550-1750) and is at the same time a work in progress, which makes this volume in the Companion series unique. The reason for this is not only the quality of the authors and the chapters they have produced, but also the fact that the study of Reformed Orthodoxy has in recent years taken an entirely new approach and has received renewed and spirited attention, whose results have so far not been brought together in one book. The renewed interest and reappraisal of this period in intellectual history is reflected in this work in which an international team of renowned scholars give an oversight of this fascinating period in intellectual history. Contributors include Willem van Asselt, Aza Goudriaan, Irena Backus, Mark Beach, Christian Moser, Anton Vos, Tobias Sarx, Andreas Mühling, Carl Trueman, Graeme Murdock, Joel Beeke, Sebastian Rehnman, Scott Clark, John Fesko, Luca Baschera, Maarten Wisse, Hugo Meijer, Pieter Rouwendal, and John Witte.
