"Faith. Absolute belief in something beyond flesh, blood, and steel, it has served to inspire great deeds among men, depthless horror and infinite charity in frustratingly equal measure. It can terrify and it can inspire, it can be treasured as a spark of nobility against the nihilism of man; or abhorred, rightly, as a fever upon the mind."
