Born in controversy and raised in university settings, the Lutheran reform movement was embroiled immediately, publicly, and perennially in theological disputes and political battles. While controversies during Martin Luther's lifetime centered on disagreements with Rome and Geneva, present and later differences emerged over interpreting Luther's and Melanchthon's theologies on such issues as governmental interference, liturgical practices, justification's implications for good works and sin, the Lord's supper, and election. It is this defining dis-concord, alternating with attempts at concord and conciliation, that is reflected in the documents newly translated in this indispensable documentary companion to The Book of Concord, which includes the works of Agricola, Eck, Chemnitz, Melanchthon, and Luther. --
