I believe part of the attraction of Billy Graham was that many people found him amusing. Postman characterizes him as principally an entertainer.
In the chapter "Shuffle Off to Bethlehem," Postman compares the 20th century televangelist with 17th-19th century spiritual leaders:
> “Television’s strongest point is that it brings personalities into our hearts, not abstractions into our heads. That is why CBS’ programs about the universe were called “Walter Cronkite’s Universe.” One would think that the grandeur of the universe needs no assistance from Walter Cronkite. One would think wrong. CBS knows that Walter Cronkite plays better on television than the Milky Way. And Jimmy Swaggart plays better than God. For God exists only in our minds, whereas Swaggart is there, to be seen, admired, adored. Which is why he is the star of the show. And why Billy Graham is a celebrity, and why Oral Roberts has his own university, and why Robert Schuller has a crystal cathedral all to himself. ”

> “It would be a serious mistake to think of Billy Graham or any other television revivalist as a latter-day Jonathan Edwards or Charles Finney. Edwards was one of the most brilliant and creative minds ever produced by America. His contribution to aesthetic theory was almost as important as his contribution to theology. His interests were mostly academic; he spent long hours each day in his study. He did not speak to his audiences extemporaneously. He read his sermons, which were tightly knit and closely reasoned expositions of theological doctrine Audiences may have been moved emotionally by Edwards’ language, but they were, first and foremost, required to understand it. Indeed Edwards’ fame was largely a result of a book, Faithful Narrative of the Surprising Work of God in the Conversion of Many Hundred Souls in Northampton, published in 1737. A later book, A Treatise Concerning Religious Affections, published in 1746, is considered to be among the most remarkable psychological studies ever produced in America.”
