First half: Very very good stories using themes in religions and horrifying them. Not to make statements socially/religiously, but just taking these themes and twisting them. Really excellent writing/ideas.
Second half: Scholarly essays. One on angels and demons and the possible origins of their myths/religious integration and how they're common themes throughout religion in general. This essay while maybe well researched, is a dull read. Also Cardin limited his scope to the middle east. No comparisons to African, Celtic, north/south/central American ancient religions, etc. It was a very western centric essay.
The other's didn't interest me. One that is a scholarly essay on Romero's movies. Sounds cool, but its just more the same as the above. The Last is about how a certain part of the bible can be read as horror....doesn't the entire thing, new or old, read like an epic horror novel?
edit:
Forgot, I wanted to give a quote from one of the short stories:
"God looks out through each of our eyes, an abyss of insatiable hunger and infinite teeth, and the dark light of His consciousness makes each of us a lamp that illuminates a new terrible truth."
