"The Metaphor of the Wall of Separation: Baptists and the First Amendment" by William D. Underwood explores the historical relationship between Baptists and the concept of church-state separation. Underwood traces the origins of the metaphor, particularly through the influence of Roger Williams, and examines its significance during colonial America. The article highlights how Baptists, once a persecuted minority, championed religious liberty and the separation of church and state. However, it also notes the shift in perspective among some modern Baptists who challenge the separation, favoring government involvement in religious matters.
