In America, religious dissent is as vital as it is elusive. Like the secretions of the pituitary, the juices of dissent are essential to ongoing life even if we do not always know precisely how, when or where they perform their tasks, and the not knowing - the flimsy, filmy elusiveness - is supremely characteristic of America's expressions of religious dissent. For in the United States no stalwart orthodoxy stands ever ready to parry the sharp thrust or clever feints of dissent.
