Each religious sect has its own physiognomy. The Methodists have acquired a face; the Quakers, a face; the nuns, a face. An Englishman will pick out a dissenter by his manners.
If 'god' is a metaphysical term, then it cannot be even probable that a god exists. For to say that 'God exists' is to make a metaphysical utterance which cannot be either true or false. And by the same criterion, no sentence which purports to describe the nature of a transcendent god can possess any literal significance.
If religion were true, its followers would not try to bludgeon their young into an artificial conformity; but would merely insist on their unbending quest for truth, irrespective of artificial backgrounds or practical consequences.
