I started exploring Christianity from an archetypal or psychological lens last year, and have found it really rewarding. I've put in thousands of hours of westernized Buddhist oriented meditation (I think "Pragmatic Dharma" is the term), and ultimately found it and the communities attached to it cultures of avoidance that loses something in its detachment of meditation technology from its larger context. I also grew up vaguely Presbyterian and hated it, so this was a great moment for me to reclaim my heritage on my own terms.
I started with various books of the Nag Hammadi collection, reading the excellent Meyer translations, and started noticing some metaphors that felt like "hidden signposts" in the text (and had some relevance to some ideas in Buddhism). Gospel of Thomas and especially Gospel of Philip felt like they map quite well to non-dual ideas in Buddhism.
I decided after some explorations of gnostic text to jump back into the gospels, wondering if I noticed the same kinds of hidden signposts there. I started this exploration during a trip to London with my wife, where I went and hunted down a copy of Bruce Rogers's amazing Oxford Lectern Bible at the Church of England reading room. What a beautiful bible -- it's so forward thinking that it feels like it was typeset last year, but while it is a beautiful piece, the King James translation of the bible is pretty incomprehensible. This little journey led me to the Sarah Ruden translations of the gospels, and as soon as I read them I felt the same kind of resonance.
This all eventually led me to Cynthia Bourgeault's amazing "The Heart of Centering Prayer," which explores the non-dual kind of ideas in esoteric Christianity and lays out the practice of centering prayer as a basis of Christian spirituality. And I would remiss if I didn't mention Jacob Needleman: Esoteric Christianity was good, but his "Money and the Meaning of Life," really helped me put my own relationship with money in perspective.
This is all a long winded way of saying: Christianity has a rich set of amazing spiritual resources, but they need to be consumed in a sort of non-literal way, where you're meeting the authors in the same mind as they were when they wrote the text. I'd also note that this kind of reading is not scholarly, the point isn't to find the right answer but to impute a larger meeting by meeting the author with your own struggles.
We live in a time that is committed to a materialist reductionist mindset, but I believe that humans are naturally mystical beings, and that we leave a lot of real meaning on the table when we reduce the world down into solely material order.
Rob Burbea explored these ideas (largely inspired by James Hillman's concept of "soulmaking") in his soulmaking dharma (https://hermesamara.org/), the idea being an extension of emptiness: if all is fabrication, why wouldn't we make meaning that is beautiful?
I'm sure I'm coming off quite a bit rambly, but it's very exciting to see such a resource on the HN front page. If you read my comment and feel any similar excitement, please check my profile and feel free to email me!
