The Exposition of 1 John and An Exposition upon Matthew V-VII are William Tyndale’s two major exegetical writings, published respectively in 1531 and 1533 in Antwerp. By this period Tyndale’s English translations of the New Testament and Pentateuch had both been printed, and he was preparing a revised version of the former to be published in 1534. Among the books he produced in the interim are these verse-by-verse commentaries on St. John’s first epistle and on Jesus’s Sermon on the Mount. In them Tyndale characteristically alternates between fierce polemics and solemn homilies that together, as has been claimed, amount to the most complete articulation of his theological positions. This volume replaces the nineteenth-century editions on which scholars and students have long relied by providing an original-spelling text of each Exposition with notes recording substantive textual variants in all sixteenth-century editions; an introduction and extensive commentary documenting, in particular, parallels and differences between the two texts and Tyndale’s other works, the works of Luther and other reform theologians, and the works of the Church Fathers and others; plus a comprehensive glossary, appendices, and indices.
