Utilizing Erastus’s correspondence, this book offers a synthetic treatment of Erastus’s career in the Palatinate including his role in the territory’s conversion, the Heidelberg Catechism, the church discipline controversy, as well as his refutation of Paracelsus and Johann Weyer.

This study is the first monograph to attempt a synthetic treatment of the career of Thomas Erastus (1524-1583). Erastus was a central player in the conversion of the Electoral Palatinate to Reformed Christianity in the early 1560s and a co-author of the Heidelberg Catechism. In the church discipline controversy of the 1560s and 1570s, Erastus opposed the Calvinist effort to institute a consistory of elders with independent authority over excommunication. Erastus’s defeat in this controversy, and the ensuing Antitrinitarian affair, proved the watershed of his career. He turned to the refutation of Paracelsus and a debate with Johann Weyer on the punishment of witches. The epilogue tracks Erastus’s later career and the reception of his works into the seventeenth century.

Byung Soo Han intends to answer, by investigating the merger of patristic and contemporary sources in the theological method of Amandus Polanus, a significant question concerning the way in which the intellectual and methodological eclecticism of the Reformed was able to establish a coherent "system" of thought capable of defense as not only confessional but also orthodox in its theology and broadly catholic, drawing both on the thought of the Reformers and on the resources of the great tradition of Christian thought that extended back to the church fathers. From a methodological perspective, Polanus's development from the Ramistically-organized doctrinal framework of the early Partitiones, through the increasingly detailed and specialized efforts of the commentaries, disputations, and Symphonia, indicates a fairly clear, concerted effort to build toward a detailed systematic presentation – and in fact, each of these earlier efforts provided as it were building-blocks that would be incorporated into the Syntagma. This constructive labor itself serves to set aside the claim that Polanus based his theology on a deductive principle. The specific focus of the book is on the place and function of backgrounds and sources, traditional and contemporary, with particular emphasis on the place of the church fathers in Reformed orthodoxy. Polanus's patristic work, Symphonia, and its eventual impact on his full systematic work, the Syntagma, provides a singular case, within the sixteenth and seventeenth centuries, of the reformulation of patristic thought in a fully systematized form, suitable for combination with the results of biblical exegesis and contemporary doctrinal argumentation in the formulation of Reformed orthodox theology. This study attempts to assess the claim of catholicity and orthodoxy by Reformed theology, demonstrating the formative function of patristic thought in Polanus's theology. Further, the study illustrates the place of this traditionary exercise within the methodologically eclectic approach followed by Polanus and his contemporaries as they created a theology that drew not only on Scripture and contemporary philosophical assumptions but also on patristic, medieval, Reformation-era, traditionary Aristotelian, Platonic, and Ramist sources. This study, therefore, reappraises the development of Reformed orthodoxy. In Polanus's case, an older scholarship that read his theology as based on central dogmas or as an exercise of rationalism will be set aside in favor of a more nuanced view of his sources and method. Within this larger framework, Polanus's use of the fathers builds on and confirms the Reformers's assumption of catholicity in the face of the detailed polemics of Robert Bellarmine as well as confirming the point that his approach to formulation was traditionary and somewhat eclectic. Finally, the book identifies the theological cohesion of the early orthodox Reformed model, as exemplified by Polanus's thought, especially in its method of drawing together of traditionary materials from varied sources. In short, the book demonstrates the importance of the church fathers to the formulation of a Reformed orthodox and catholic theology in the context of showing, contrary to previous studies of Polanus's thought and contrary to the older stereotypes of "Calvinist" orthodoxy, that Reformed orthodoxy was neither a rigid monolith nor a matter of philosophical speculation but the product of a carefully conceived exercise in the compilation and assessment of biblical and traditionary materials.

This study explores the integral role of astrological concepts and imagery in preparing the ground for the Reformation, and in shaping the distinctive characteristics of German Christian culture through the early seventeenth century.

This study begins with an examination of Girolamo Zanchi's De Tribus Elohim (1572), setting this important defense of the doctrine of the Trinity in the immediate context of the recent rise of antitrinitarianism within the Reformed Palatinate. De Tribus Elohim focused on the grammatical peculiarity of the Hebrew word Elohim (God) in order to refute the biblicism of its contemporary antitrinitarians. In doing so, Zanchi's argument followed an exegetical thread common within the late medieval case for the doctrine of the Trinity, but which ran contrary to the exegetical sensibilities of many of Zanchi's own Reformed colleagues. This disagreement over the correct interpretation of the word Elohim, then became a touchstone for distinguishing between two different approaches to the Hebrew text with the Reformed Church of the late sixteenth century, and becomes a significant piece in understanding the development of Reformed exegesis.

A great deal of scholarship has too often juxtaposed scholasticism and piety, resulting in misunderstandings of the relationship between Protestant churches of the early modern era and the theology taught in their schools. But more recent scholarship, especially conducted by Richard A. Muller over the last number of decades, has remapped the lines of continuity and discontinuity in the relation of church and school. This research has produced a more methodologically nuanced and historically accurate representation of church and school in early modern Protestantism. Written by leading scholars of early modern Protestant theology and history and based on research using the most relevant original sources, this collection seeks to broaden our understanding of how and why clergy were educated to serve the church.

An account of the astrological controversies that arose in Renaissance Italy in the wake of Giovanni Pico della Mirandola’s Disputationes adversus astrologiam divinatricem, published in 1496.

A fresh look at the importance of natural and international law in the religious politics at the heartlands of the Reformation, from the Low Countries, the German principalities up to Transylvania; from Niels Hemmingsen to Gian Battista Vico; from religious reasons for the universalist claims of natural law to political arguments for the sacred polity, their tension and creative potential.

For centuries, countless Christians have turned to the Westminster Standards for insights into the Christian faith. These renowned documents—first published in the middle of the 17th century—are still considered by many to be some of the most beautifully written summaries of the Bible's teaching ever produced. Church historian John Fesko walks readers through the background and theology of the Westminster Confession, the Larger Catechism, and the Shorter Catechism, helpfully situating them within their original context. Organized according to the major categories of systematic theology, this book utilizes quotations from other key works from the same time period to shed light on the history and significance of these influential documents.

Coolhaes was a Reformed preacher, a writer of theology, a critic of the churches of his day, and an advocate of religious diversity. Coolhaes opposed much of the building up of the organization of the Reformed Church in the Northern Netherlands and Dutch Republic in the late sixteenth and early seventeenth centuries. The struggle between Coolhaes and the Leiden magistrates on one side and the Leiden consistory and fellow-preacher Pieter Cornelisz on the other encapsulated the question of authority which was being asked by many. At the same time, Coolhaes' theology, especially his Spiritualistic understanding of the sacraments, his Erastianism, and his views on free will made him suspicious to his Reformed colleagues. The latter of which leading him later to be labeled »the forerunner of Arminius and the Remonstrants«. All this eventually led to his defrocking at the synod of Middelburg and soon after to excommunication from the Reformed Church. The question this book answers, therefore, is: What sort of church would the critic Coolhaes himself have wanted to design for the new Republic?The first part of the book gives a new biographical sketch. Fresh information, sources, and un-examined works by Coolhaes himself have been uncovered since H.C. Rogge's nineteenth-century biography. In the second part the ecclesiology of Coolhaes takes center stage: His ideal church would have been characterized by diversity, for diversity of religious confessions in the same society would stabilize it and diversity of views even within a confession would not harm it.
