The Churches stand for traditional and collective convictions which in the case of many of their adherents are no longer based on their own inner experience but on unrelenting belief, which is notoriously apt to disappear as soon as one begins thinking about it. The content of belief then comes into collision with knowledge, and it often turns out that the irrationality of the former is no match for the ratiocinations of the latter. Belief is no adequate substitute for inner experience, and where this is absent even a strong faith which came miraculously as a gift of grace may depart equally miraculously.
