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. Some attempts have been made to portray Buddhism in an exclusivistic framework by pointing out that the implication that those who do not accept the teachings of the Buddha, such as the Noble Eightfold Path, are destined to repeat the cycle of suffering through endless reincarnations; while those who practice the true way can reach enlightenment. Neo-Buddhist groups sometimes consider their tradition the true path to enlightenment and engage in strong evangelical efforts to influence those they consider to be in darkness. Several sects associated with Nichiren Buddhism may be included in this category. However, many followers of Eastern religions are not exclusivist. For example, there are millions of Buddhists who would also consider themselves to follow Confucianism or Taoism. Some Christians have argued that religious pluralism is an invalid or self-contradictory concept. Maximal forms of religious pluralism claim that all religions are equally true, or that one religion can be true for some and another for others. Most Christians hold this idea to be logically impossible from the Principle of contradiction. The two largest Christian branches, the Catholic Church and the Eastern Orthodox Church, both claim to be the "one true church" and that "outside the true Church there is no salvation"; Protestantism however, which has many different denominations, has no consistent doctrine in this regard, and has a variety of different positions regarding religious pluralism. A number of Christian denominations assert that they alone represent the one true church – the church to which Jesus gave his authority in the Great Commission. The Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox communion and the Assyrian Church of the East each understands itself as the one and only original church.
