Not hyper-literally. Who says that Ezekiel's vision will be fulfilled literally? Ezekiel doesn't claim this; nor does the rest of the Canon.
Can you explain the spritual or allegorical meaning of the physical descriptions of the Ezekiel Temple? I doubt it, unless you find some occultic meaning in the words. Ezekiel is describing a literal temple with physical dimensions. Unless there is some occultic meaning to the description that is hidden from all but the initiated, then I think the proper hermenutic is to assume that he was prophesying of the Temple which will be built in the future.
Do you have some occultic knowledge of what the various alleged "symbols" described in Ezekiel 40-48 mean?
Personally I try to avoid occultic interpretations of passages that can be interpreted literally. While there may be secondary and tertiary symbolic meanings, if the scripture is subject to literal interpretation, then we need to realize that TRUTH demands that the literal interpretation take precedence.
The prophesies regarding Christ's first coming were not fulfilled allegorically or spsiritually or occultically, but literally. I suspect that any prophesy of Christ's second coming that can be reasonably interpreted literally will be fulfilled literally.
Deuteronomy warns us against prophets whose prophesies do not come to pass (literally). By your interpretation if we judge Ezekiel by the standard of Deuteronomy, we have to conclude that he was a false prophet. Or maybe we can just allegorize the warnings in Deuteronomy.
Is there a single verse of scripture that you are not willing to allegorize if it conflicts with your eschatology?
