Do you know the difference between Jewish Kabbalah and Christian Kabbalah?
Ah ... we have to tread carefully here.
The first point, as Aerist noted, is that Kabbalah is a way of 'mapping' a certain order of experience, shaped within a given religious tradition.
Man's speculation on 'the supernatural' is as old as humanity, but we must be careful when we say that a given form goes back into antiquity ... rather I would say that 'spiritual speculation' has emerged and evolved over time, and taken on distinctive forms according to determinations of the times and places in which those forms have emerged.
Historically, Kabbalah emerged in 12th-13th-century Southern France and Spain, although its traces, obviously, go back to the dawn of creation, as told within the Hebrew Tradition.
So whilst the essence of the Kabbalah is universal (as is the essence of any esoteric system) the language and form is particular, in this instance to the Hebrew Tradition. You cannot really grasp that Kabbalah without first being grounded in Hebrew thinking. A lot of modern syncretic interpretation falters on this point, as it assumes a rather superficial viewpoint.
So when we say 'kabbalah' we're talking primarily of a Jewish system; when we say 'sufi' we're talking Moslem; when we say 'shingon' we're talking Buddhism; but the point is, man is the same everywhere, and there will be correspondences and cross-overs between systems, but to assume the terms are transposable, without qualification, invariably leads to error.
When we look at Christianity, really you're looking at the Hebrew Tradition viewed from an Hellenic perspective. With a few notable exceptions, the Fathers of the Church were Platonists. Offhand, I know Origen taught himself Hebrew, so he could read the Hebrew Scriptures in the original, but he was an exception.
So while Judaism has its kabbalah, an esoteric commentary informed by the Hebrew Scripture tradition, Christianity's 'kabbalah' is in fact Christian Neoplatonism, an esoteric commentary informed by the Christian Scriptures. The same goes for 'Christian Hermeticism': Take a look at "
Meditations on the Tarot".
The kaballah is founded on four fundamental methods of exegesis:
Peshat: the 'simple' or 'literal' interpretation of Scripture;
Remez: the 'allegorical' or 'esoteric' interpretation of Scripture;
Derash: the 'homiletic' or 'moral' exegesis;
Sod: the 'mystical' exegesis.
In the Christian Tradition we have 'the Four Senses of Scripture':
The literal;
The moral;
The allegorical;
The anagogical (mystical).
These four correspond to the Hebrew above, but their origins are Greek.
So I would say there's a lot of crossover, but if someone were to start talking about 'a Christian Kabbalah', then I'd say I prefer to study the original and therefore authentic (Platonic) forms, rather than a syncretic 'fixing' that's probably not too well founded in either the Hebrew or the Hellenic.
