Episode 118: Dylan Burns on Sethian Gnosticism

We know from Porphyry’s Life of Plotinus that a number of Christian texts were circulating among Plotinus’ students at Rome. For a long time these were assumed to be roughly Valentinian works, since Valentinianism was the strain of esoteric Christianity best-know to scholarship. When the Nag Hammadi Coptic library was discovered and published, however, we suddenly had versions of a number of important, highly-Platonistic religious texts, one of which – Zostrianos – is mentioned by name by Porphyry as circulating among Plotinus’ students. Study of the Zostrianos and related texts from Nag Hammadi has led to scholars coining the term ‘Sethian’ to describe a number of works with common features.

Then something unexpected happened: it turned out that there were a number of ideas in Plotinus’ thought which were also in the Sethian texts, and a number of scholars have now made the case that Plotinus was more ‘Gnostic’ than he would himself have admitted. But before we can assess the Gnosticism that may be found in Plotinus, we need as good an idea as possible about the ideas circulating among Plotinus’ Gnostic friends. Cue an episode on Sethianism.

It turns out that the Sethian Gnostic texts open a window on a fascinating, highly-apophatic, highly esoteric ancient form of Platonistic Christianity well worth studying in its own right. We are delighted to have Dylan Burns as our guide to what these texts were like, what kinds of beliefs are found in them, and to the amazing mytho-metaphysics which describe the reason the world is the way it is (i.e. really bad, ruled by evil archontes) and man’s divine destiny of escape from this flawed state of affairs.

In a long and fascinating discussion:

  • We decide on working definitions for ‘Sethian texts’, ‘Gnosticism’ as a textual typology, and open the problem of who the ancient readers of the Sethian texts, the ‘Immovable Race’, might have been,
  • We discuss the remaining textual corpus of Sethian works, the Coptic treatises The Secret Book of John (which survives in multiple shorter and longer versions in the Nag Hammadi library and the Akhmim/Berlin Codex), Allogenes, Marsanes, Zostrianos, The Three Steles of Seth, the Gospel of the Egyptians,  and outliers, and
  • What makes them distinctive – pseudepigraphic attribution, the importance of the figure of Seth, but also a distinctive style of angelology, a threefold division of world history with an eschatological end-point – along with some other fascinating descriptors, such as a very strong apophatic tendency and a distinctive blending (more in some texts than in others) of recognisably Jewish, Christian, and school-Platonist elements, and the presence of the Barbelo, a feminine self-noetising nous, the first emanation from the Great Invisible Spirit, the supreme god who is described under deeply apophatic strictures,
  • Burns’ approach to dating these texts, suggesting a second-century origin for some version of them, taking into account the amount the texts will have evolved between then and the fourth century, when our MSS likely come on the scene,
  • The question of the Platonistic character of some of our texts: Is this a case of Gnostics learning and incorporating cutting-edge philosophy into their religious worldviews, or does it instead represent the forerunner of much of the metaphysical architecture we find in Plotinus and his successors?
  • The ‘detail-oriented’ nature of the Gnostic worldview found in this literature, with its complex mythological-metaphysical architectures of immaterial realities and sub-realities all interacting in the process of creation, fall, and redemption,
  • The Sethian myth as laid out in its most detailed form in the Apocryphon of John, which preserves a theogony, cosmogony, anthropogony, and salvation history,
  • The character of the Sethian Aiôn-figures as both elements in a celestial topography and angelic or quasi-angelic beings,
  • The figure of Ialdabaoth, the ignorant demiurge-figure, described as a theriomorphic tyrant-god, and
  • The generation of the first humans by Ialdabaoth based on the archetype of the aionic anthropos; the humans have an aspect of the divine world within them, and so the aiones intervene to help free them from the grip of ignorance by granting them faculties of apprehending their true, divine nature.

Interview Bio:

Since this interview was recorded Dylan Burns has become Assistant Professor of the History of Esotericism in Late Antiquity at the University of Amsterdam’s HHP. Nice one! He is an editor of Brill’s Nag Hammadi and Manichaean Studies series. His many publications deal with ancient Gnosticism, Platonistic and Platonising religious movements, Platonism and ancient philosophy more generally, as well as the wider field of western esotericism studies. His most recent book at the time of writing is Did God Care? Providence, Dualism, and Will in Later Greek and Early Christian Philosophy. More of his works can be found in the Recommended Reading section below.

There were at the same time many Christians and others, of a contrary school of thought to the ancient philosophy (αἱρετικοὶ δὲ ἐκ τῆς παλαιᾶς φιλοσοφίας) following Adelphios and Akylinos, possessing many writings of Alexander the Libyan and Philokomos and Demostratos and Lydos, and producing Revelations (ἀποκαλύψεις) of Zoroaster and Zostrianos and Nikotheos and Allogenes and Messos and many others of this sort, themselves deceived and deceiving many [others, saying] that Plato had not penetrated to the depths of the noetic essence (ὡς δὲ τοῦ Πλάτωνος εἰς τὸ βάθος τῆς νοητῆς οὐσίας οὐ πελάσαντος).
