Religious pluralism is an attitude or policy regarding the diversity of religiousbelief systems co-existing in society. It can indicate one or more of the following:
Any of several forms of religious inclusivism. One such worldview holds that one's own religion is not the sole and exclusive source of truth, and thus acknowledges that at least some truths and true values exist in other religions. Another concept is that two or more religions with mutually exclusive truth claims are equally valid; this may be considered a form of either toleration (a concept that arose as a result of the European wars of religion) or moral relativism.
Perennialism (based on the concept of philosophia perennis) is the understanding that the exclusive claims of different religions turn out, upon closer examination, to be variations of universal truths that have been taught since time immemorial. While some perennialists are universalists who accept religious syncretism, those of the Traditionalist School reject it, and uphold the importance of the historical, "orthodox" faiths.
Sometimes as a synonym for ecumenism, i.e., the promotion of some level of unity, co-operation, and improved understanding between different religions or different denominations within a single religion.
