The gospel does in truth proclaim the redemption of reason. Obscurantism is always evil, and wilful error is always sin., All truth is God's truth; facts, as such, are sacred, and nothing is more un-Christian than to run away from them.
For dishonest thinking, however well-intentioned, can only discredit the cause it serves, and must in the long run boomerang disastrously on those who indulge in it.
