Matthew Thiessen offers a nuanced and wide-ranging study of the nature of Jewish thought on Jewishness, circumcision, and conversion. Examining texts from the Hebrew Bible, Second Temple Judaism, and early Christianity, he gives a compelling account of the various forms of Judaism from which the early Christian movement arose.Beginning with analysis of the Hebrew Bible, Thiessen argues that there is no evidence that circumcision was considered to be a rite of conversion to Israelite religion. In fact, circumcision, particularly the infant circumcision practiced within Israelite and early Jewish society, excluded from the covenant those not properly descended from Abraham. In the Second Temple period, many Jews began to subscribe to a definition of Jewishness that enabled Gentiles to become Jews. Other Jews, such as the author of Jubilees, found this definition problematic, reasserting a strictly genealogical conception of Jewish identity. As a result, some Gentiles who underwent conversion to Judaism in this period faced criticism because of their suspect genealogy.Thiessen's examination of the way in which Jews in the Second Temple period perceived circumcision and conversion allows a deeper understanding of early Christianity. Contesting Conversion shows that careful attention to a definition of Jewishness that was based on genealogical descent has crucial implications for understanding the variegated nature of early Christian mission to the Gentiles in the first century C.E.

The Mediterranean and its hinterlands were the scene of intensive and transformative contact between cultures in the Middle Ages. From the seventh to the seventeenth century, the three civilizations into which the region came to be divided geographically – the Islamic Khalifate, the Byzantine Empire, and the Latin West – were busily redefining themselves vis-à-vis one another. Interspersed throughout the region were communities of minorities, such as Christians in Muslim lands, Muslims in Christian lands, heterodoxical sects, pagans, and, of course, Jews. One of the most potent vectors of interaction and influence between these communities in the medieval world was inter-religious conversion: the process whereby groups or individuals formally embraced a new religion. The chapters of this book explore this dynamic: what did it mean to convert to Christianity in seventh-century Ireland? What did it mean to embrace Islam in tenth-century Egypt? Are the two phenomena comparable on a social, cultural, and legal level? The chapters of the book also ask what we are able to learn from our sources, which, at times, provide a very culturally-charged and specific conversion rhetoric. Taken as a whole, the compositions in this volume set out to argue that inter-religious conversion was a process that was recognizable and comparable throughout its geographical and chronological purview.

The pervasiveness of the Christian religion has long been treated as one of the key features of medieval society. Indeed, Europe in the Middle Ages is often described simply as a Christian culture. Yet what do we mean when we say that medieval Europe was a Christian society, and what did it mean to be a Christian in the Middle Ages? These questions are fundamental to any understanding of the Middle Ages, yet the variety of theoretical approaches and conclusions represented in this carefully selected and provocative collection of key works in the field highlights the complexity of the answers. Introducing students to medieval Christianity, James L. Halverson presents a rich array of readings that offers a variety of ways to study the history of religion within a chronological setting. His opening chapter and introductions to each section and selection frame the essays and provide a strong conceptual framework to build upon. Making it clear that scholars have approached religion from many perspectives and used many different methodologies, this collection presents some of the best scholarship of religion as culture and practice, emphasizing the ongoing attempt to understand the social and cultural aspects of medieval Christianity.
