The Christian cartoonist E. J. Pace (1880–1946) began his career during the fundamentalist–modernist controversy of the 1920s. Pace often reacted against liberal evangelicalism, or modernism, in his cartoons, and Islam appeared alongside it on several occasions. This article discusses for the first time Pace's Islam-inspired cartoons. It explores the socioreligious contexts of their creation and the theological reasons why Pace used them as a tool with which to attack modernism and its perceived threat to America's souls. Pace may have cartooned Islam to bolster fundamentalist evangelicalism, but his cartoons also create moments of unintended unity that remain culturally relevant today.
