This book collects together thirteen essays on the Reformed Church, its leading scholars, their interactions, writings and changing scholarly culture. All but two of these essays have been previously published, but have been revised and are presented here in three thematic sections. In the fullest of these, the author examines the internal debates of the Church, and considers the relationship between several of its Fathers. The following sections present three essays that emphasise the originality and significance of Peter Martyr Vermigli's contribution, and, finally, consider the influence of three later figures: John Diodati, Jan Amos Comenius and Galeazzo Caracciolo. This book does not attempt a systematic and complete treatment of the development of the Reformed Church in the sixteenth and seventeenth centuries, but offers instead a series of studies which, taken as a group, make a case for a Church which was ‘neither monolithic, nor monochrome’ but which represented a ‘variegated Reformed tradition’, the product of complex ‘reciprocal interaction between persons and situations’. These essays provide a minute and deeply learned inspection of a range of sources in order to understand more correctly the intellectual relationships of Calvin and Bullinger, of Bullinger and Beza, of Vermigli and Calvin. That which considers the Consensus Tigurinus, reconstructing its development, language and theology, is a fine illustration of the way in which the Reformed tradition was subtly wrought of a plurality of influences and approaches.
