In the 1960s and later, these categories were challenged by a mostly self-educated Friend, Lewis Benson, a New Jersey printer by training, a theologian by vocation. Immersing himself in the corpus of early Quaker writings, he made himself an authority on George Fox and his message. In 1966, Benson published Catholic Quakerism, a small book that sought to move the Society of Friends to what he insisted was a strongly pro-Fox position of authentic Christianity, entirely separate from theological liberalism, churchly denominationalism, or rural isolation. He created the New Foundation Fellowship, which blazed forth for a decade or so, but had about disappeared as an effective group by the end of the century.
