Belief system in the context of "Eliminativism"

Doctrine (from Latin: doctrina, meaning 'teaching, instruction') is a codification of beliefs or a body of teachings or instructions, taught principles or positions, as the essence of teachings in a given branch of knowledge or in a belief system. The etymological Greek analogue is 'catechism'.

Often the word doctrine specifically suggests a body of religious principles as promulgated by a church. Doctrine may also refer to a principle of law, in the common-law traditions, established through a history of past decisions.

Organized religion, also known as institutional religion, is religion in which belief systems and rituals are systematically arranged and formally established, typically by an official doctrine (or dogma), a hierarchical or bureaucratic leadership structure, and a codification of proper and improper behavior.

In religion, mythology, and fiction, a prophecy is a message that has been communicated to a person (typically called a prophet) by a supernatural entity. Prophecies are a feature of many cultures and belief systems and usually contain divine will or law, or preternatural knowledge, for example of future events. They can be revealed to the prophet in various ways depending on the religion and the story, such as visions, or direct interaction with divine beings in physical form. Stories of prophetic deeds sometimes receive considerable attention and some have been known to survive for centuries through oral tradition or as religious texts.

Religious exclusivism, or religious exclusivity, is the doctrine or belief that only one particular religion or belief system is true. This is in contrast to religious pluralism.

Philosophy of religion is "the philosophical examination of the central themes and concepts involved in religious traditions". Philosophical discussions on such topics date from ancient times, and appear in the earliest known texts concerning philosophy. The field involves many other branches of philosophy, including metaphysics, epistemology, logic, ethics, aesthetics, philosophy of language, and philosophy of science.

The philosophy of religion differs from religious philosophy in that it seeks to discuss questions regarding the nature of religion as a whole, rather than examining the problems brought forth by a particular belief-system. The philosophy of religion differs from theology in that it aims to examine religious concepts from an objective philosophical perspective rather than from the perspective of a specific religious tradition. The philosophy of religion also differs from religious studies in that it seeks to evaluate the truth of religious worldviews. It can be carried out dispassionately by those who identify as believers or non-believers.

Religious pluralism is an attitude or policy regarding the diversity of religious belief systems co-existing in society. It can indicate one or more of the following:

• Recognizing and tolerating the religious diversity of a society or country, promoting freedom of religion, and defining secularism as neutrality (of the state or non-sectarian institution) on issues of religion as opposed to opposition of religion in the public forum or public square that is open to public expression, and promoting friendly separation of religion and state as opposed to hostile separation or antitheism espoused by other forms of secularism.
• 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.
• As a term for the condition of harmonious co-existence between adherents of different religions or religious denominations.
