Built into our law system is the idea of the equal toleration under the law of all religions. It is a short step in people’s thinking from equal toleration under the law to equal validity. The principle that all religions should be treated equally under the law and have equal rights does not carry with it the necessary inference that therefore all religions are valid. Even a cursory, comparative examination of the world’s religions reveals points of radical contradiction among them, and unless one is prepared to affirm the equal truth of contradictories, one must not be able to embrace this fallacious assumption.
