Biography: J. Gresham Machen's Response to Modernism

In 1993, John Piper presented a message titled "J. Gresham Machen's Response to Modernism" at the Bethlehem Conference for Pastors. Listen to this biographical sketch on Machen here. (Transcription of message here.)

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."
