Traditionalism (Catholic Church, 19th-century ideology)
Traditionalism, in the context of 19th-century Catholicism, refers to an ideology that held that all metaphysical, moral, and religious knowledge derives from God's revelation to man and is handed down in an unbroken chain of tradition. It denied that human reason by itself has the power to attain to any truths in these domains of knowledge. It arose, mainly in Belgium and France, as a reaction to 18th-century rationalism. It was eventually condemned in a number of papal decrees and finally ruled out by the First Vatican Council in 1870.
