Context paragraphs:
The Presbyterian Guardian: On 7 October 1935, Rev. John Gresham Machen established "The Presbyterian Guardian" to serve as the voice of conservative Presbyterianism in the United States, the main denomination of which, the Presbyterian Church in the United States of America, had become fairly liberal and modernist.  James T. Dennison, Jr., compiler of a cumulative index to the magazine, wrote that "The Presbyterian Guardian" was "conceived it controversy."  Machen had been encountering significant theological disagreements with Dr. Samuel G. Craig, editor of "Christianity Today" (1930–1949) (not to be confused with "Christianity Today", the magazine founded in 1956).  In response to perceived modernism in the magazine, Machen began publishing The Guardian with a small group of conservative ministers and laymen, hiring Rev. H. McAllister Griffiths as the first Editor.

The Scandal of the Evangelical Mind: The Scandal of the Evangelical Mind (published 1994) is a book by evangelical Christian scholar Mark A. Noll, who is currently Francis A. McAnaney Professor of History at the University of Notre Dame.  As a critique of the waning influence of intellectual pursuits within the American evangelical community, the book is both a scholarly analysis of evangelical anti-intellectualism and "an epistle from a wounded lover" by an intellectual who feels betrayed by evangelical Christianity's neglect of "sober analysis of nature, human society, and the arts".  "Scandal" was named "Book of the Year" by "Christianity Today", the popular neo-evangelical Christian magazine.  In 2004, ten years after its initial publication, "Christianity Today" claimed that the book had "arguably shaped the evangelical world (or at least its institutions) more than any other book published in the last decade".

What's So Amazing About Grace?: What's So Amazing About Grace?  is a 1997 book by Philip Yancey, an American journalist and editor-at-large for "Christianity Today".

"What's So Amazing About Grace?"  includes Bible stories, anecdotes from Yancey's life, accounts of historical events and other stories.  These include a modern retelling of the Parable of the Prodigal Son, an account of Yancey's friendship with Mel White who came out as homosexual, a comparison of the teachings of early Christians Pelagius and Augustine of Hippo, and a summary of Karen Blixen's short story "Babette's Feast".
