Here are basic texts that reveal the spirituality of the Modern Devout, especially during the early years of the movement from 1380 to 1430. The "Modern Devotion" movement, which was originated by a Dutchman, Master Geerte Grote, is the classic expression of later medieval religious life.

The Devotio Moderna, or Modern Devout, puzzled their contemporaries. Beginning in the 1380s in market towns along the Ijssel River of the east-central Netherlands and in the county of Holland, they formed households organized as communes and forged lives centered on private devotion. They lived on city streets alongside their neighbors, managed properties and rents in common, and worked in the textile and book trades, all the while refusing to profess vows as members of any religious order or to acquire spouses and personal property as lay citizens. They defended their self-designed style of life as exemplary and sustained it in the face of opposition, their women labeled "beguines" and their men "lollards," both meant as derogatory terms. Yet the movement grew, drawing in women and schoolboys, priests and laymen, and spreading outward toward Münster, Flanders, and Cologne. The Devout were arguably more culturally significant than the Lollards and Beguines, yet they have commanded far less scholarly attention in English. John Van Engen's magisterial book keeps the Modern Devout at its center and thinks through their story anew. Few interpreters have read the Devout so insistently within their own time and space by looking to the social and religious conditions that marked towns and parishes in northern Europe during the fifteenth century and examining the widespread upheavals in cultural and religious life between the 1370s and the 1440s. In Sisters and Brothers of the Common Life, Van Engen grasps the Devout in their humanity, communities, and beliefs, and places them firmly within the urban societies of the Low Countries and the cultures we call late medieval.

In the terms of Durheimian sociology, conversion is a fait social. Although they are rarely treated as a cultural phenomenon, conversions can obviously be examined for the norms, values and presuppositions of the cultures in which they take place. Thus conversion can help us to shed light on a particular culture. At the same time, the term evokes a dramatic appeal that suggests a kind of suddenness, although in most cases conversion implies a more gradual process of establishing and defining a new - religious - identity. From 21-24 May 2003, the University of Groningen hosted an international conference on 'Cultures of Conversion'. The contributions have been edited in two volumes, which pay special attention to the modes of language and idiom in conversion literature, the meaning and sense of religious-ideological discourse, the variety of rhetorical tropes, and the effects of the conversion narrative with allusions to religious or political conventions and idealizations. The present volume contains theoretical contributions on the theory of conversion, with special attention to the rational choice theory, and on the history of research into conversion. It also offers stimulating case studies, ranging from the late Middle Ages to present times and taken from Germany, Great Britain and The Netherlands. The other volume, Cultures of Conversion, offers in-depth studies of conversion that are mainly taken from the history of India, Islam and Judaism, ranging from the Byzantine period to the new Muslimas of the West.

Written by one of the world's greatest authorities on Martin Luther, this is the definitive biography of the central figure of the Protestant Reformation. “A brilliant account of Luther’s evolution as a man, a thinker, and a Christian. . . . Every person interested in Christianity should put this on his or her reading list.”—Lawrence Cunningham, Commonweal “This is the biography of Luther for our time by the world’s foremost authority.”—Steven Ozment, Harvard University “If the world is to gain from Luther it must turn to the real Luther—furious, violent, foul-mouthed, passionately concerned. Him it will find in Oberman’s book, a labour of love.”—G. R. Elton, Journal of Ecclesiastical History
