I am reading a book that was recommended by my Albion Awakening co-authors: The Magical Battle of Britain, a selection of letters from the Second World War by Dion Fortune, edited by Gareth Knight (1993).
Dion Fortune was the pseudonym of Violet Mary Firth, who was perhaps the most respected and influential magical practitioner of modern times to come from Britain; and importantly, from my point of view, she was a sincere and devout Christian - of an Esoteric kind.
Her idea was that - after war was declared, and as Britain prepared for the possibility of invasion, it was important to encourage people by spiritual means: to build-up the folk and racial soul of the British; by means of directed meditations of many people.
Reading the book, it seems distinctly possible to me that what she did was of genuine benefit - especially when regarded as one specific manifestation of a spiritual 'mobilisation' that had multiple facets - most obviously seen with Winston Churchill becoming the national leader.
It is noteworthy that DF herself displayed an extremely unusual, and admirable, combination of strength of character, creative inspiration, ethical solidity - and yet a disinterested and altruistic absence of ego.
What she 'asked for' in these magical-group-meditations was always, it seems, very carefully restricted to the spiritual level (not seeking specific physical results, not personal advantage); and was therefore benign. She was, in her small scale fashion, one of the rare examples of an effective and natural woman leader - a mini Elizabeth the First!
However, as I read I also developed the conviction that this Magical Battle of Britain was probably the last time that such a thing was possible. Indeed, even before the end of the 39-45 war, the British national consciousness had changed qualitatively - and in the direction of being both less spiritual, and less group-ish.
The way that Dion Fortune used symbolism (sword, sceptre, grail), the concept of a national soul which was also a racial soul, the use of visualisation (eg of guarding angels)... these are essentially the spiritual categories of an earlier, pre-modern phase of human consciousness. By 1939 they were merely residual in the spirit of Albion; and became possible and effective only briefly and for one more time, under the exceptional demands of that era.
Very rapidly afterwards there was a dwindling and disappearance of both symbolic power, and the capacity of an individual to immerse in the group-soul. Before the war was done, Britain had begun to become pretty much what it is now; materialistic and anti-Christian; hedonically aiming at 'comfort and convenience'; and its national ideology established as Leftist-bureaucratic and totalitarian (as Orwell made clear, based on his wartime experiences).
My understanding is that these changes were underlain by that developmental change in British consciousness which was only briefly interrupted by the Swan Song described in the Magical Battle of Britain.
As symbolism and immersive group spirituality dwindled and then became impossible; so the churches dwindled, leftist-hedonic-materialism waxed.
And (as I see it, anyway!) the necessity for a Romantic Christianity became incrementally more and more obvious and urgent.
