Kraphol & Lippy (1999) states, "Under the tutelage of Biola's dean, Reuben A. Torrey, Fuller developed a religious perspective that was strongly weighted toward fundamentalism and dispensationalism.

Fuller then dabbled in volunteer religious work in the Los Angeles area for several years until his fundamentalist views forced him and many of his Sunday school class to split from Placentia Presbyterian in 1925.

The broadcasts were noted for their music, featuring the Old Fashioned Revival Hour Choir and quartet, accompanied by organist George Broadbent and pianist Rudy Atwood.

Aided by his wife, Grace, the Old Fashioned Revival Hour program created a family-like atmosphere, and by 1942 it had attracted an audience of over 10 million listeners worldwide.

Co-authors Kraphol and Lippy write the following about his legacy: "When Fuller died in 1968, his important role as a major figure in the development of post-World War II neoevangelicalism was not fully appreciated.

Yet, his organizational skill, his masterful use of the radio medium, his vision for Christian higher education, and his willingness to moderate the more divisive aspects of his own fundamentalism background made him a significant force in the development of modern American evangelical ethos.

"[9] The book Pagan Christianity by George Barna and Frank Viola notes Fuller's popularization of the use of the terminology "personal savior" when speaking of Jesus.
