Indifferentism

Indifferentism is the belief held by some that no one religion or philosophy is superior to another.

Political indifferentism relates to the policy of a state that treats all the religions within its borders as being on an equal footing before the law of the country. Meanwhile, religious indifferentism is the belief that all religions are equally valid. However, in Catholic usage religious indifference is a term for the behavior of "deny[ing] that it is the duty of man to worship God by believing and practicing the one true religion".
