By Chilton Williamson, Jr., Crisis Magazine - Further, liberalism is sinful in itself—sinful in its philosophical assumptions, its moral and political doctrines, and its anti-clerical history, as Felix Sard y Salvany, a Spanish priest in the late 19th century, demonstrated in El Liberalismo es pecato (Liberalism Is a Sin). Thus, a priest who is a liberal is a heretic as well, and a priest who sets his loyalty to the religion of liberalism above his loyalty to the Catholic faith is a traitor.
