Read an interesting quote from Bertrand Russell (on St. Thomas Aquinas) that seems to nail the central issue non-religious people have with faith and those who profess it:

“Aquinas “already knows the truth; it is declared in the Catholic faith. If he can find apparently rational arguments for some parts of the faith, so much the better; if he cannot, he need only fall back on revelation. The finding of arguments for a conclusion already given in advance is not philosophy, but special pleading.”
