Ferdinand Christian Baur & Roger Hodgson 
Christian Gnosis [PDF ebook] 
Christian Religious Philosophy in Its Historical Development

Ferdinand Christian Baur’s Die Christliche Gnosis, first published in 1835, is considered by many to be the most important book on Gnosticism published in the nineteenth century and is a pivotal work within Baur’s canon. Baur’s unique thesis of a link between ancient and modern religious philosophy, as well as his conception of Gnosticism — developed through dialogues with his predecessors and contemporaries — consolidate Christian Gnosis as an important contribution to Christian theology. In this seminal work, written over a hundred years before the manuscript discovery at Nag Hammadi, Baur classifies the gnostic systems in terms of how they conceive the relationship of Christianity to Judaism and paganism, describing them in detail. He then goes on to describe the criticism of and reaction to gnosis in church history, before contending with the modern religious philosophy of his time, discussing Boehme, Schelling, Schleiermacher and Hegel. Christian Gnosis is Baur’s first great religio-historical study, and Robert Brown’s masterful translation ensures the work is as impactful today as it was on its first publication.
