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.
