Jerome Zanchius

Overview

Jerome Zanchius, or Girolamo Zanchi (1516-1590), was an Italian-born Reformed theologian who taught at Strasbourg and Heidelberg after fleeing persecution in his homeland.1 He is best remembered for his treatise on predestination, later translated into English by Augustus Toplady as The Doctrine of Absolute Predestination Stated and Asserted, a book that became a flashpoint in the eighteenth-century Calvinist-Arminian controversy.2

Life and Ministry

Zanchi was born on February 2, 1516, in Alzano, near Bergamo in northern Italy, to a nobleman.3 His father died in the plague of 1528 and his mother only three years later, leaving him an orphan by age fifteen, the same year he entered a monastery of the Augustinian Order of Regular Canons, where he studied Aristotle, languages, and divinity.3 At the order’s school in Lucca he attended Peter Martyr Vermigli’s lectures on Romans, an experience that proved decisive in turning him toward the Reformation; he stayed on at Lucca even after Vermigli’s own forced exile in 1542.3

Growing persecution against the Reformation eventually drove Zanchi out of Italy. He left by way of Geneva in 1551 and accepted the professorship of Old Testament at the Academy of St. Thomas in Strasbourg, where he taught from 1553 for roughly a decade, becoming embroiled in disputes with Lutheran colleagues there over the Augsburg Confession and the Lord’s Supper.3 In 1563 he left Strasbourg to pastor the Italian Protestant congregation at Chiavenna, in the Grisons.3 In 1567 the Elector Palatine Frederick III called him to a divinity professorship at the University of Heidelberg alongside Zacharias Ursinus; Zanchi took up the post in 1568 and received a doctorate the same year, and held it for about nine years.3 When Frederick III died in 1576 and the Palatinate briefly returned to Lutheranism, Zanchi took the pastorate at the Casimirianum academy in Neustadt an der Haardt, where he remained until his death on November 19, 1590, while visiting Heidelberg.3

Theological Contribution

The Doctrine of Absolute Predestination

Zanchi’s best-known work is his Latin treatise on predestination, later rendered into English and abridged by Augustus Toplady as The Doctrine of Absolute Predestination Stated and Asserted.2 In it Zanchi took care to distinguish the Reformed doctrine from mere fatalism: true predestination, he argued, is not “a sort of blind, rapid, overbearing impetus, which, right or wrong, with means or without, carries all things violently before it, with little or no attention to the peculiar and respective nature of second causes.”4 On the will’s bondage to sin, Zanchi drew on Martin Luther’s argument that once free will has lost its liberty to do good, it becomes, in Luther’s words, “an empty term, whose reality is lost. And a lost liberty, according to my grammar, is no liberty at all.”5

A source for later Reformed dogmatics

Zanchi belonged to the generation of Reformed scholastic theologians who systematized the Reformation’s teaching after its first generation, named alongside Vermigli, Beza, Ursinus, and Bullinger as one who followed Augustine’s monergism against Rome’s and the Remonstrants’ synergism.1 His collected theological works, the Operum theologicorum, became a standard reference point for later Reformed dogmatics: Herman Bavinck’s Reformed Dogmatics cites Zanchi across several separate loci, including the doctrine of Scripture, the doctrine of faith, the divine attributes, and creation.67

On the beatific vision, the question of whether the blessed will see God’s own essence with their bodily eyes in eternity, the Lutheran theologian Johann Gerhard’s survey of the question grouped Zanchi with Vermigli among “the Calvinists” who joined “the Scholastics and all the Papists” in answering no, holding that only an intellectual, not a corporeal, vision of the divine essence is possible even in glory.8

Historical Significance

Zanchi’s predestination treatise outlived him by two centuries as a live controversy. Toplady’s English translation and abridgment of the work became caught up in the Calvinist-Arminian dispute of 1770s England when John Wesley circulated his own condensed version of Toplady’s abridgment in a form Toplady judged a misrepresentation; Toplady answered with A Letter to the Rev. Mr. John Wesley: Relative to his Pretended Abridgment of Zanchius on Predestination (1770).2 The dispute drew Zanchi’s two-centuries-old treatise directly into the eighteenth century’s argument between Calvinism and Arminianism over free will and grace.
