Indifferentism

Indifferentism, in Roman Catholic theology, describes the belief that no one religion or philosophy is superior to another. The Catholic Church ascribes indifferentism to all atheistic, materialistic, pantheistic, and agnostic philosophies. There are three basic types of indifferentism in Catholic theology: absolute, restricted, and liberal or latitudinarian indifferentism. Indifferentism was first explicitly identified and condemned by Pope Gregory XVI, in his encyclical Mirari vos.
