Machen on the mindset that comes from relativism:
"This temper of mind is hostile to precise definitions. Indeed nothing makes a man more unpopular in the controversies of the present day than an insistence upon definition of terms. . . . Men discourse very eloquently today upon such subjects as God, religion, Christianity, atonement, redemption, faith; but are greatly incensed when they are asked to tell in simple language what they mean by these terms."
-J. Gresham Machen
