John Calvin

Jean Cauvin (Latinized as Calvin) was a French humanist lawyer trained at the universities of Orléans and Bourges. He converted to the Reformation around 1533 — the date he himself describes as a sudden conversion (subita conversio), though the precise circumstances remain obscure. By 1535 he was an exile in Basel, and in 1536, at the age of twenty-six, he published the first edition of the Christianae Religionis Institutio — six chapters intended as an introduction for new readers of Reformed theology. The final 1559 edition would be four volumes and eighty chapters. It is the single most influential systematic theology of the Reformation.

Calvin's distinctive theological emphasis was the sovereignty of God in all things — most controversially in the doctrine of election, but more pervasively as a habit of mind that subordinated every doctrine to the question of who God is and what God does. His treatment of providence, the unity of the Old and New Testaments, the threefold office of Christ (prophet, priest, king), and the church as a school of the elect all proceed from this center. He was not the doctrinal innovator that polemical opponents made him out to be — most of his theology is a careful systematization of Augustine, with the Reformation's particular sharpening on sola fide and sola scriptura.

Geneva, where Calvin was effectively pastor and de facto theological architect from 1541 until his death in 1564, was the laboratory in which Reformed church order was worked out. The Ecclesiastical Ordinances of 1541 set up the fourfold office of pastor, doctor (teacher), elder, and deacon — the template that would shape Presbyterian, Reformed, Congregational, and ultimately a great deal of free-church Protestantism. The Genevan Academy, founded in 1559, became a training ground for Reformed pastors and theologians from across Europe. The Geneva of Calvin was not a theocracy in the strict sense — the magistracy and the consistory remained separate — but the city was the most thorough working-out of "Reformed religion as social order" the 16th century produced.

Calvin's defenders and critics both have to reckon with the execution of Michael Servetus in 1553. The Spanish anti-Trinitarian had escaped from Catholic authorities in France and arrived in Geneva. Calvin testified against him; the Genevan magistracy condemned him and burned him at the stake. Calvin had urged beheading rather than burning. The episode is a genuine moral stain that no responsible account of the Reformation should soften — but it should also be placed in its 16th-century context, where every major Protestant and Catholic authority would have done the same and most did. The theological architect of Reformed Christianity was also, on this point, a man of his century.
