Leppin's careful research overturns conceptions of late-medieval mysticism as inherently works-oriented, illuminating instead how Tauler and others influenced Luther's emerging views on indulgences, the Passion, the Eucharist, and theological tenets including the concepts of law and gospel, justification, and the priesthood of all believers. United with Christ continues to expand upon threads drawn in Leppin's 2024 Sola: Christ, Grace, Faith, and Scripture Alone in Martin Luther's Theology, helping us understand the emergence of the Reformation as an innovative series of developments from, rather than an absolute rupture with, late-medieval Christianity.
Volker Leppin is the Horace Tracy Pitkin Professor of Historical Theology at Yale Divinity School. He is author of twenty books in the field of medieval and Reformation studies.
