This compilation of writings from Erasmus and Luther's great debate—over free will and grace, and their respective efficacy for salvation—offers a fuller representation of the disputants' main arguments than has ever been available in a single volume in English. Included are key, corresponding selections from not only Erasmus' conciliatory A Discussion or Discourse concerning Free Will and Luther's forceful and fully argued rebuttal, but—with the battle now joined—from Erasmus' own forceful and fully argued rebuttal of Luther. Students of Reformation theology, Christian humanism, and sixteenth-century rhetoric will find here the key to a wider appreciation of one of early modern Christianity's most illuminating and disputed controversies.
