Beginning with Walter Bauer in 1934, the denial of clear orthodoxy in early Christianity has shaped and largely defined modern New Testament criticism, recently given new life through the work of spokesmen like Bart Ehrman. Spreading from academia into mainstream media, the suggestion that diversity of doctrine in the early church led to many competing orthodoxies is indicative of today's postmodern relativism. Authors Köstenberger and Kruger engage Ehrman and others in this polemic against a dogged adherence to popular ideals of diversity. Köstenberger and Kruger's accessible and careful scholarship not only counters the "Bauer Thesis" using its own terms, but also engages overlooked evidence from the New Testament. Their conclusions are drawn from analysis of the evidence of unity in the New Testament, the formation and closing of the canon, and the methodology and integrity of the recording and distribution of religious texts within the early church.

Eighty years ago, Walter Bauer promulgated a bold and provocative thesis about early Christianity. He argued that many forms of Christianity started the race, but one competitor pushed aside the others, until this powerful 'orthodox' version won theday. The victors rewrote history, marginalizing all other perspectives and silencing their voices, even though the alternatives possessed equal right to the title of normative Christianity. Bauer's influence still casts a long shadow on early Christian scholarship. Were heretical movements the original forms of Christianity? Did the heretics outnumber the orthodox? Did orthodox heresiologists accurately portray their opponents? And more fundamentally, how can one make any objective distinction between 'heresy' and 'orthodoxy'? Is such labeling merely the product of socially situated power? Did numerous, valid forms of Christianity exist without any validating norms of Christianity? This collection of essays, each written by a relevant authority, tackles such questions with scholarly acumen and careful attention to historical, cultural-geographical, and socio-rhetorical detail. Although recognizing the importance of Bauer's critical insights, innovative methodologies, and fruitful suggestions, the contributors expose numerous claims of the Bauer thesis (in both original and recent manifestations) that fall short of the historical evidence.

A lively examination of the heretics who helped Christianity become the world’s most powerful religion. From Arius, a fourth-century Libyan cleric who doubted the very divinity of Christ, to more successful heretics like Martin Luther and John Calvin, this book charts the history of dissent in the Christian Church. As the author traces the Church’s attempts at enforcing orthodoxy, from the days of Constantine to the modern Catholic Church’s lingering conflicts, he argues that heresy—by forcing the Church to continually refine and impose its beliefs—actually helped Christianity to blossom into one of the world’s most formidable religions. Today, all believers owe it to themselves to grapple with the questions raised by heresy. Can you be a Christian without denouncing heretics? Is it possible that new ideas challenging Church doctrine are destined to become as popular as Luther’s once-outrageous suggestions of clerical marriage and a priesthood of all believers? A delightfully readable and deeply learned new history, Heretics overturns our assumptions about the role of heresy in a faith that still shapes the world. “Wright emphasizes the ‘extraordinarily creative role’ that heresy has played in the evolution of Christianity by helping to ‘define, enliven, and complicate’ it in dialectical fashion. Among the world’s great religions, Christianity has been uniquely rich in dissent, Wright argues—especially in its early days, when there was so little agreement among its adherents that one critic compared them to a marsh full of frogs croaking in discord.” —The New Yorker

According to the commonly held view, early Christianity was a time of great harmony, and heresy emerged only at a later stage. To the contrary, Gerd Ludemann argues that the time from the first Christian communities to the end of the second century was defined by struggle by various groups for doctrinal authority. Drawing on a wealth of data, he asserts that the losers in this struggle actually represented Christianity in its more authentic, original form. Orthodoxy has been defined by the victors in this struggle and it is they who subsequently silenced alternative views and labeled them heretical. Ludemann's findings are important as well as liberating for the understanding of both Christianity and the Bible. Readers will gain a new understanding of Jesus and the early church from this compelling and controversial book.

Heresy is a central concept in the formation of Orthodox Christianity. Where does this notion come from? This book traces the construction of the idea of ‘heresy’ in the rhetoric of ideological disagreements in Second Temple Jewish and early Christian texts and in the development of the polemical rhetoric against ‘heretics,’ called heresiology. Here, author Robert Royalty argues, one finds the origin of what comes to be labelled ‘heresy’ in the second century. In other words, there was such as thing as ‘heresy’ in ancient Jewish and Christian discourse before it was called ‘heresy.’ And by the end of the first century, the notion of heresy was integral to the political positioning of the early orthodox Christian party within the Roman Empire and the range of other Christian communities. This book is an original contribution to the field of Early Christian studies. Recent treatments of the origins of heresy and Christian identity have focused on the second century rather than on the earlier texts including the New Testament. The book further makes a methodological contribution by blurring the line between New Testament Studies and Early Christian studies, employing ideological and post-colonial critical methods.

In Heresy, leading religion expert and church historian Alister McGrath reveals the surprising history of heresy and rival forms of Christianity, arguing that the church must continue to defend what is true about Jesus. He explains that remaining faithful to Jesus’s mission and message is still the mandate of the church despite increasingly popular cries that traditional dogma is outdated and restricts individual freedom.

How do we distinguish between truth and error? Which differences in belief should be tolerated? A leading researcher, Bowman shows how and where Christians must take a stand and calls for reasoned evaluation in love. Includes appendixes, a glossary of frequently misused words, and lists of other resources.

Leading scholars from Italy and the United States offer a fresh and nuanced image of the religious reform movements on the Italian peninsula in the sixteenth and seventeenth centuries. United in their conviction that religious ideas can only be fully understood in relation to the particular social, cultural, and political contexts in which they develop, these scholars explore a wide range of protagonists from popes, bishops, and inquisitors to humanists and merchants, to artists, jewelers, and nuns. What emerges is a story of negotiations, mediations, compromises, and of shifting boundaries between heresy and orthodoxy. This book is essential reading for all students of the history of Christianity in early modern Europe.
