What! a spurious faith, a false
  prophet, a counterfeit Messiah, the fulfilment of a promised blessing!
  Is this the mode in which God fulfils His promises? To discover a parallel
  between Christianity and this "spurious revelation," is the object
  of the whole book, and it is very ably dealt with by a succession of curious
  analogies in the prophetical anticipations,1 morality, doctrine,
  ritual, scriptures, heresies, crusades, and civilisation of Mohammedanism,
  Judaism and Christianity. These analogies, prove nothing, because the
  foundation of the argument, as we have shown, is unsound; but they contain a
  vast fund of useful information, which will well repay the trouble of a
  perusal.
