I don't think it's that big of a mystery. Just break down what Myatt's main ideological precursors are.

Hitler - His consistent praise for NS, his involvement in NS orgs, imo probably his actual belief system, with O9A itself being secondary
Nietzsche - The overall ethos of O9A. Heavily colors his interpretation of NS
Spengler and Toynbee - The idea of civilizational cycles
Asimov in all likelihood - Psychohistory/aeonics
Jung - Acausaulity and gender alchemy
Gardnerian Wicca - A lot of the ritual flavor of the Black Book and the emphasis on women

None of those things are anything we should be overly surprised that a Nazi was reading. Hitler and Nietzsche go without saying. Spenglerian civilizational cycles of decadence and rebirth are absolutely essential part of Fascism's ideological structure. Jung praised Hitler and was friends with Miguel Serrano so Nazis tend to like him. Asimov is basically Spengler in fictional form. Wicca contributed the least, mostly just aesthetics, but even that is very palingenetic in that it's a reconstruction of a supposedly peculiarly English form of religion so the appeal to Nazis is obvious.

I don't see much at all that's Christian about Myatt's writings and if I had to pick a single influence that seems the most important I'd say Nietzsche.

Forgot to say about Myatt's influences that this is basically always how Fascist intellectualism works, it's wildly syncretic and it's more of picking and choosing different thinkers because they agree with your politics than it is any attempt to form a coherent philosophy.

If you look at the Nouvelle Droite they do a smarter version of the same shit. Never any synthesis or original analysis, just picking and choosing thinkers like Heidegger and writers like Celine for inclusion in their 'canon' based on whether they liked Hitler and hated Jews enough. It's an ideology driven by aesthetics and the unrestrained id, the intellectualism is a post hoc justification.

Now that I reflected on it they could have gotten the Salome thing from Vril society; which has claimed to be a modern extension of the Knights Templar. However, I know for a fact that Vril society uses a bust of Ceaser instead of John the baptist.
 Still a very strange inclusion from my perspective as a less rational and more spiritual person.

I haven't looked into it but isn't there some question whether the Vril Society even existed?

I'm not sure if it originally existed but the fact is Vril society exists in the modern world today in a very limited capacity, I actually used to have pictures someone here posted of a small Vril society cell.
