After his suspension from the Los Angeles Archdiocese, DuBay wrote an article entitled We Must Reform the Church, which sharply criticized the conservative tilt of Roman Catholicism and stressed the need for the church to modernize its message and its practices. The article appeared in the June 4, 1966 edition of the Saturday Evening Post and elicited numerous responses from readers. Included in the files are letters and cards addressed to DuBay regarding both his article and his progressive vision for the Roman Catholic church.
