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.

Ryan McGraw presents an introduction of historic Reformed orthodoxy (1560–1790) and its research methodology. This book establishes the tools needed to study Reformed scholasticism and its potential benefits to the church today by describing the nature of Reformed scholasticism and outlining the research methodology, the nature and the character of this branch of theology, and providing a retrospective view on the contemporary appropriations. McGraw discusses the proper use of primary and secondary sources and offers instructions on how to write historical theology. Each chapter draws extensive examples from primary source evidence, published books and articles in this field; as well as engaging with a wide range of ancient and medieval sources. This volume is an excellent guide for students as it teaches them how to identify primary and secondary sources, suggests good links and tips for learning Latin; and provides an overview of the most important figures in the period.

Amandus Polanus (1561–1610) has often been described as a highly significant theologian, but also a neglected one. Part of Polanus' significance comes from his inclusion of ethics and practical application in his discussion of theology and the way in which his theology mixes Ramist dichotomies and the scholastic distinctions common in Christian Aristotelianism. Stephen B. Tipton shows how Polanus' understanding of God's essence and attributes is built upon the ground of scripture, arranged with the aid of logical arguments and reasoning, and aimed at the worship and glory of the Triune God. Tipton defends this conclusion against previous research which suggests that Polanus' theology is grounded in rationalism and subordinates the Trinity beneath an Aristotelian notion of God's perfect unity. This research not only corrects these previous notions about Polanus, but it also provides greater insight into the early Reformed Orthodox period and the theology that arose from that time.

What is the real meaning of the church for Christian life? If we confess Christian faith, the church is one of the twelve articles, which implies that the church is rather important. In the creeds of the early church catholicity is confessed as characteristic for the church. This means that the church cannot exist without catholicity. What does this qualification mean? In this study the author listens to the understanding of the concept of catholicity in the theology of Ignatius, Cyprian, Cyril, Augustine and Vincent. In the second part of the book some representatives of the reformed tradition are analyzed, namely John Calvin, James Ussher, John Owen, Herman Bavinck and Gerrit Berkouwer. This analysis leads to a comparison between the early church and the reformed tradition. Listening to theologians from the early church and the reformed tradition, Van Vlastuin presents an up-to-date concept of the catholicity of the church which clarifies among others that the visibility of the church belongs to the essence of Christ's body, that practicing the catholicity of the church is necessary against denominationalism and party formation, that loss of catholicity leads to spiritual and theological impoverishment, that the understanding of catholicity implies also orthodoxy with consequences for the interpretation of 'semper reformanda' and that the consciousness of catholicity is related to the citizenship of two worlds.

Grace and Freedom addresses the issue of divine grace in relation to the freedom of the will in Reformed or "Calvinist" theology in the late sixteenth and early seventeenth century. It focuses on the work of the English Reformed theologian William Perkins, especially his role as an apologist of the Church of England, defending its theology against the Roman Catholic polemic, and specifically against the charge that Reformed theology denies human free choice. Perkins and his Reformed contemporaries affirm that salvation occurs by grace alone and that God is the ultimate cause of all things, but they also insist on the freedom of the human will and specifically the freedom of choice in a way that does not conform to modern notions of "libertarian freedom" or "compatibilism." In developing this position, Perkins drew on the thought of Reformers such as Peter Martyr Vermigli and Zacharias Ursinus, on the nuanced positions of medieval scholastics, and several contemporary Roman Catholic representatives of the so-called "second scholasticism." His work was a major contribution to early modern Reformed thought both in England and on the continent. His influence in England extended both to the Reformed heritage of the Church of England and to English Puritanism. On the continent, his work contributed to the main lines of Reformed orthodoxy and to the piety of the Dutch Second Reformation.

Recently there has been a revival of interest in the views held by Reformed theologians within the parameters of confessional orthodoxy. For example, the doctrine known as 'hypothetical universalism'--the idea that although Christ died in some sense for every person, his death was intended to bring about the salvation only for those who were predestined for salvation. Michael Lynch focuses on the hypothetical universalism of the English theologian and bishop John Davenant (1572-1641), arguing that it has consistently been misinterpreted and misrepresented as a via media between Arminian and Reformed theology. A close examination of Davenent's De Morte Christi, is the central core of the study. Lynch offers a detailed exposition of Davenant's doctrine of universal redemption in dialogue with his understanding of closely related doctrines such as God's will, predestination, providence, and covenant theology. He defends the thesis that Davenant's version of hypothetical universalism represents a significant strand of the Augustinian tradition, including the early modern Reformed tradition. The book examines the patristic and medieval periods as they provided the background for the Lutheran, Remonstrant, and Reformed reactions to the so-called Lombardian formula ('Christ died sufficiently for all, effectually for the elect'). It traces how Davenant and his fellow British delegates at the Synod of Dordt shaped the Canons of Dordt in such a way as to allow for their English hypothetical universalism.
