About this book

Essential Early Reformed Writings from a Renaissance Master

Peter Martyr Vermigli stands as one of the most influential yet underappreciated figures of the Protestant Reformation. This inaugural volume of The Peter Martyr Library presents his earliest and most foundational works, offering readers unprecedented access to the theological mind that shaped Reformed thought across Europe.

Written during Vermigli’s pivotal transition from Italian monastery to Protestant exile, these three works reveal a mature theologian grappling with essential questions of Christian faith, biblical authority, and ecclesiastical reform. His exposition of the Apostles’ Creed demonstrates the pastoral heart of a scholar who declared that “Christianity is a profession of wisdom, heavenly and divine.” The Strasbourg theses showcase his innovative pedagogical method, while his treatise on schism provides a reasoned defense of the Protestant separation from Rome.

This volume captures the intellectual ferment of the 16th century, when Renaissance humanism met Reformation theology. Vermigli’s synthesis of Aristotelian philosophy, patristic learning, and biblical exegesis offers timeless insights for contemporary Christians seeking to understand the foundations of Protestant orthodoxy.

FROM THE BOOK

“Christianity is nevertheless a profession of wisdom, heavenly and divine. The end it holds in view is not any degree or condition whatever, but man’s ultimate happiness, desired by all. It deals not with treasures of gold, jewels, or silver, but with the heavenly kingdom. The sum total and impact of Christianity bears not merely on the use of a day, or the way one lives through a week, but on the ordering of our entire life. Therefore, everyone who bears the name or mark of Christian should constantly give himself to the diligent study of the faith.”

Praise for this work

“Peter Martyr Vermigli was everywhere in the sixteenth century—abbot of a monastery in Naples, teacher and colleague of Cranmer in Oxford, pastor and theologian in Zurich. His erudition was immense, from Aristotle and Augustine and Aquinas to Bucer and Zwingli, not to mention his biblical commentaries. These nine volumes will be a major resource for all who seek to learn from the leading figures of the sixteenth century and, in our own context, to foster ecumenical conversations rooted in the love and truth of Christ.”

– Matthew Levering

James N. Jr. and Mary D. Perry Chair of Theology, Mundelein Seminary

“Legend has it that Peter Martyr Vermigli wandered out of the Italian Alps as the ‘ready-made reformer,’ a fact confirmed by the respect he commanded among sixteenth-century Reformed churches. A theologian of the first order, trained in catholic theology and fully committed to the Reformation, students of Scripture would do well to read, mark, and meditate upon the biblically faithful, theologically insightful, and practically oriented work of this great theologian.”

– J. V. Fesko

Harriet Barbour Professor of Systematic and Historical Theology, Reformed Theological Seminary, Jackson, Mississippi

“Peter Martyr is a name too little known and appreciated, but his clarity, rigor, and meaningful contribution to early Reformation theology make his work well worth our time. Whether he is carefully navigating the hypostatic union, the eucharist, or questions about justification, this powerful Reformer helps us better appreciate not only 16th-century Reformed distinctives, but why it all might matter for Christian life. I am thrilled that the Davenant Institute is now making these significant volumes available as high-quality hardback reprints. I hope they will fill the shelves of many personal and professional libraries.”

– Kelly M. Kapic

Professor of Theological Studies, Covenant College

“There are few servants of the Reformation era who had such theological insight and widespread influence as Peter Martyr Vermigli. Yet his labours have never truly received either the attention or the appreciation that they deserve. It is therefore a delight to see this stunning new edition of his works come to publication, which will hopefully inspire fresh engagement with his ideas and his legacy. There are treasures here – for Christians and for churches – that will amply reward careful reading and judicious reflection.”

– Professor Paul T. Nimmo

King’s Chair of Systematic Theology, University of Aberdeen

“This is a wonderful collection from an exemplary Hebraist, exegete, preacher, theologian and controversialist. Forced to move between the Continent and British Isles following his conversion to the Reformation, Vermigli impressed people wherever he went and will undoubtedly impress readers today. The Florentine was a trained Dominican and Renaissance humanist. He exhibited deep familiarity with the Patristic, Classical, and Scholastic corpora. He is not for the faint-hearted, but the effort of reading him will be rewarded 1000-fold.”

– Christina Larsen

Associate Professor of Theology, Grand Canyon Theological Seminary & College of Theology

“The very fact that Peter Martyr Vermigli has become something of a household name in Reformed theology is due in large part to the Davenant Institute’s republication of his various works at a reasonable price. The Peter Martyr Vermigli Library covers a whole panoply of this Italian Reformer’s writings, ranging from exposition of Aristotle’s moral philosophy to the catechetical theology of his commentary on the Apostles’ Creed. Vermigli—more so than Calvin—represents the intellectual and theological high-mark of early, 16th century Reformed orthodoxy. This collection has and will continue to provide theologians, ministers, or even those simply interested in Reformational Protestantism a one-stop shop for early modern theological, philosophical, and biblical reflection. With pleasure I say: Tolle lege!”

– Michael Lynch

Professor of Christian History, Davenant Hall

“Peter Martyr Vermigli was one of the preeminent theologians of the Protestant Reformation. For far too long his contributions to the development of Reformed theology have been neglected. With the publication of this library, his rich, thoughtful, and textured theology and philosophy will finally be widely available!”

– Gayle Doornbos

Associate Professor of Theology, Dordt University

“Peter Martyr Vermigli must be listed among the most remarkable men who shaped one of the most remarkable centuries in the long span of human history. The fact that the man and his writings have been barely known is a scandal and that is why the publication of The Peter Martyr Vermigli Library is such good news. Vermigli was one of the most important figures in the Protestant Reformation and, strangely enough, in the formation of what became the English constitutional tradition. The Peter Martyr Vermigli Library represents a great recovery and is to be celebrated.”

– R. Albert Mohler, Jr.

President & Centennial Professor of Christian Theology, The Southern Baptist Theological Seminary

“This is a wonderful collection from an exemplary Hebraist, exegete, preacher, theologian and controversialist. Forced to move between the Continent and British Isles following his conversion to the Reformation, Vermigli impressed people wherever he went and will undoubtedly impress readers today. The Florentine was a trained Dominican and Renaissance humanist. He exhibited deep familiarity with the Patristic, Classical, and Scholastic corpora. He is not for the faint-hearted, but the effort of reading him will be rewarded 1000-fold.”

About the Editors

Mariano Di Gangi resides in Toronto after a career as pastor in Canada and the United States, as a teacher at the Ontario Theological Seminary, and as an evangelist. His interest in Peter Martyr resulted in his Bachelor of Divinity thesis at The Presbyterian College, Montreal, 1949, on Peter Martyr Vermigli’s life and work, including “The Creed” as appendix. That early work has now been expanded and published as Peter Martyr Vermigli: Renaissance Man, Reformation Master (1993), while the Credo begins the present volume.

Joseph C. McLelland is emeritus professor of McGill University and of The Presbyterian College, Montreal, and general editor of the Peter Martyr Library. His writings in philosophy and theology include The Visible Words of God: The Sacramental Theology of Peter Martyr Vermigli (1957) and The Life, Early Letters and Eucharistic Writings of Peter Martyr (with G. E. Duffield; 1989).

Philip M. J. McNair served as professor of Italian and departmental head of the University of Birmingham. He retired to Cambridge, where he continues to lecture in the Faculty of Theology and pursue writing assignments. He has written entries for several encyclopedias, and is the author of Peter Martyr in Italy (1967).
