This book offers the first detailed commentary on the Gnostic treatises reported by Irenaeus in Adversus Haereses 1.29–30. It is argued that these texts represent the earliest tangible layer of the Gnostic literary tradition and served as sources for the Apocryphon of John and other later works. They also formed the starting point for Valentinus and his followers, who sought to reconcile the ideas of the Gnostics with apostolic Christianity. The book also shows that Irenaeus and later heresiologists referred to “the Gnostics” as a specific group among the great mass of heretics.

“Gnosticism” has become a problematic category in the study of early Christianity. It obscures diversity, invites essentialist generalisations, and is a legacy of ancient heresiology. However, simply to conclude with “diversity” is unsatisfying, and new efforts to discern coherence and to synthesise need to be made. The present work seeks to make a fresh start by concentrating on Irenaeus’ report on a specific group called the “Gnostics” and on his claim that Valentinus and his followers were inspired by their ideas. Following this lead, an attempt is made to trace the continuity of ideas from this group to Valentinianism. The study concludes that there is more continuity than has previously been recognised. Irenaeus’ “Gnostics” emerge as the predecessors not only of Valentinianism, but also of Sethianism. They represent an early, philosophically inspired form of Christ religion that arose independently of the New Testament canon. Christology is essential and provides the basis for the myth of Sophia. The book is relevant for all students of Christian origins and the early history of the Church.

Few literary innovations have exercised as much influence upon Christian attitudes toward internal diversity as has the practice of organizing the names and alleged misdeeds of rival teachers into heresy catalogues. For two millennia, followers of Jesus have employed the heresy catalogue as a powerful weapon in internal struggles for legitimacy, authority, and supremacy. Despite its enduring popularity and influence within the Christian tradition, the heresy catalogue remains an underappreciated polemical genre among historians of early Christianity. Guilt by Association explores the creation, publication, and circulation of heresy catalogues by second- and early third-century Christians. Polemicists made use of these religious blacklists, which include the names of heretical teachers along with summaries of their unsavory doctrines and nefarious misdeeds, in order to discredit opponents and advocate their expulsion from the "authentic" Christianity community. The heresy catalogue proved to be especially effective because it not only recast rival teachers as menacing adversaries, but also reinforced such characterizations by organizing otherwise unaffiliated teachers into coherent intellectual, social, and scholastic communities that are established and sustained by demonic powers. Geoffrey Smith focuses especially on the earliest Christian heresy catalogues, including those found within the works of Justin, Irenaeus, and Hegesippus, to shed new light upon the complex process through which early Christianity took shape.

This study offers new translations of significant parts of his work, critically based on a complete reconstruction of the original Greek in the French series Sources Chretiennes.

Most anyone interested in such topics as creation mythology, Jungian theory, or the idea of "secret teachings" in ancient Judaism and Christianity has found "gnosticism" compelling. Yet the term "gnosticism," which often connotes a single rebellious movement against the prevailing religions of late antiquity, gives the false impression of a monolithic religious phenomenon. Here Michael Williams challenges the validity of the widely invoked category of ancient "gnosticism" and the ways it has been described. Presenting such famous writings and movements as the Apocryphon of John and Valentinian Christianity, Williams uncovers the similarities and differences among some major traditions widely categorized as gnostic. He provides an eloquent, systematic argument for a more accurate way to discuss these interpretive approaches. The modern construct "gnosticism" is not justified by any ancient self-definition, and many of the most commonly cited religious features that supposedly define gnosticism phenomenologically turn out to be questionable. Exploring the sample sets of "gnostic" teachings, Williams refutes generalizations concerning asceticism and libertinism, attitudes toward the body and the created world, and alleged features of protest, parasitism, and elitism. He sketches a fresh model for understanding ancient innovations on more "mainstream" Judaism and Christianity, a model that is informed by modern research on dynamics in new religious movements and is freed from the false stereotypes from which the category "gnosticism" has been constructed.

This book about receptions of Simon Magus uncovers further facets of one who was held to be the evil archetype of heretics. Ephraim Nissan and Alberto Ferreiro explore how Simon Magus has been represented in text, visual art, and music. Special attention is devoted to the late medieval Catalan painter Lluís Borrassà and the Italian librettist and musician Arrigo Boito. The tradition of Simon Magus’ demonic flight, ending in his crashing down, first appears in the patristic literature. The book situates that flight typologically across cultures. Fascinating observations emerge, as the discussion spans flight of the wicked in rabbinic texts, flight and death of King Lear’s father and a Soviet-era Buryat Buddhist monk, flight and doom of the fool in an early modern German broadsheet, and more. The book explains and moves beyond extant scholarly wisdom on how the polemic against Mani (the founder of Manichaeism) was tinged with hues of Simon Magus. The novelty of this book is that it shows that Simon Magus’ receptions teach us a great deal about the contexts in which this archetype was deployed.

Valentinus was a popular, influential, and controversial early Christian teacher. His school flourished in the second and third centuries C.E. Yet because his followers ascribed the creation of the visible world not to a supreme God but to an inferior and ignorant Creator-God, they were from early on accused of heresy, and rumors were spread of their immorality and sorcery. Beyond Gnosticism suggests that scholars approach Valentinians as an early Christian group rather than as a representative of ancient "Gnosticism"-a term notoriously difficult to define. The study shows that Valentinian myths of origin are filled with references to lifestyle (such as the control of emotions), the Christian community, and society, providing students with ethical instruction and new insights into their position in the world. While scholars have mapped the religio-historical and philosophical backgrounds of Valentinian myth, they have yet to address the significance of these mythmaking practices or emphasize the practical consequences of Valentinians' theological views. In this groundbreaking study, Ismo Dunderberg provides a comprehensive portrait of a group hounded by other Christians after Christianity gained a privileged position in the Roman Empire. Valentinians displayed a keen interest in mythmaking and the interpretation of myths, spinning complex tales about the origin of humans and the world. As this book argues, however, Valentinian Christians did not teach "myth for myth's sake." Rather, myth and practice were closely intertwined. After a brief introduction to the members of the school of Valentinus and the texts they left behind, Dunderberg focuses on Valentinus's interpretation of the biblical creation myth, in which the theologian affirmed humankind's original immortality as a present, not lost quality and placed a special emphasis on the "frank speech" afforded to Adam by the supreme God. Much like ancient philosophers, Valentinus believed that the divine Spirit sustained the entire cosmic chain and saw evil as originating from conspicuous "matter." Dunderberg then turns to other instances of Valentinian mythmaking dominated by ethical concerns. For example, the analysis and therapy of emotions occupy a prominent place in different versions of the myth of Wisdom's fall, proving that Valentinians, like other educated early Christians, saw Christ as the healer of emotions. Dunderberg also discusses the Tripartite Tractate, the most extensive account to date of Valentinian theology, and shows how Valentinians used cosmic myth to symbolize the persecution of the church in the Roman Empire and to create a separate Christian identity in opposition to the Greeks and the Jews.
