no, you're quite right.  it's a mixed metaphor.  Cathedral and (Nonconformist) Chapel
would associate properly, or Magisterium and Free Thinker perhaps.
the use of Bazaar is peculiar too; i suspected the author was one of those who
referred to his books as `tomes'.  perhaps he had in mind that it was noisy,
bright and colourful, and if you took something without paying you got your hand chopped off.
no, that can't be right ...
