is aimed at the majority of the faithful in every religious tradition, not at Tillich's blameless parish of one.
Despite the considerable exertions of men like Tillich who have attempted to hide the serpent lurking at the foot of every altar, the truth is that religious faith is simply unjustified belief in matters of ultimate concern—specifically in propositions that promise some mechanism by which human life can be spared the ravages of time and death. Faith is what credulity becomes when it finally achieves escape velocity from the constraints of terrestrial discourse— constraints like reasonableness, internal coherence, civility, and candor. However far you feel you have fled the parish (even if you are just now adjusting the mirror on the Hubble Space Telescope), you are likely to be the product of a culture that has elevated belief, in the absence of evidence, to the highest place in the hierarchy of human virtues. Ignorance is the true coinage of this realm—"Blessed are those who have not seen and have believed" (John 20:29)—and every child is instructed that it is, at the very least, an option, if not a sacred duty, to disregard the facts of this world out of deference to the God who lurks in his mother's and father's imaginations.
