This book contains the proceedings from the Codex Judas Congress, the first international conference held to discuss the newly-restored Tchacos Codex. Given that the Tchacos Codex is a newly-conserved ancient book of Christian manuscripts which had yet to be discussed collaboratively by a body of scholars, the research conducted and published within this book by the members of the Codex Judas Congress is nothing less than a landmark in Gnostic studies. Scholars address issues of identity and community, portraits of Judas, astrological lore, salvation and praxis, text and intertext, and manuscript matters. Although the contributions show a variety of interpretations of the Tchacos texts, several points of agreement emerge, including the assessment that the Codex belonged to early Christians in conflict with other Christians who belonged to the apostolic or conventional church. Contributors include: Grant Adamson, Johanna Brankaer, Fernando Bermejo Rubio, Serge Cazelais, April D. DeConick, Ismo Dunderberg, Niclas Forster, Wolf-Peter Funk, Simon Gathercole, Matteo Grosso, Lance Jenott, Karen King, Nicola Denzey Lewis, Alastair Logan, Antti Marjanen, Marvin Meyer, Elaine Pagels, Birger A. Pearson, Pierluigi Piovanelli, James M. Robinson, Gesine Schenke Robinson, Kevin Sullivan, Franklin Trammel, Johannes van Oort, Bas van Os, Louis Painchaud, Tage Petersen, John D. Turner, and Gregor Wurst.
