In this startling original work of historical detection, Mark D. Jordan explores the invention of Sodomy by medieval Christendom, examining its conceptual foundations in theology and gauging its impact on Christian sexual ethics both then and now. This book is for everyone involved in the ongoing debate within organized religions and society in general over moral judgments of same-sex eroticism. "A crucial contribution to our understanding of the tortured and tortuous relationship between men who love men, and the Christian religion—indeed, between our kind and Western society as a whole. . . . The true power of Jordan's study is that it gives back to gay and lesbian people our place in history and that it places before modern theologians and church leaders a detailed history of fear, inconsistency, hatred and oppression that must be faced both intellectually and pastorally."—Michael B. Kelly, Screaming Hyena "[A] detailed and disturbing tour through the back roads of medieval Christian thought."—Dennis O'Brien, Commonweal "Being gay and being Catholic are not necessarily incompatible modes of life, Jordan argues. . . . Compelling and deeply learned."— Virginia Quarterly Review
