(I didn't read the other long answer - too lazy)
but the above is what I thought... poe uses religious images so many times and I could never quite make out if he really belived in it or just used it as pictures just the way you use a sertain colour or technique when painting a picture to produce a certain impression...
so now I think that is exactly what he did (most of the times)
(thx for this topic, otherwise I would have started up one myselve just about this question.. )
