Religious exclusivism, or exclusivity, is the doctrine or belief that only one particular religion or belief system is true. This is in contrast to religious pluralism, which believes that all religions provide valid responses to the existence of God.
Buddhism
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 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. Such shallow interpreters do not take into account that in his prior Avatar Buddha had said that he comes into everyone's lives through many different names and forms. 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.
s believe that Islam is the original and primordial faith, or fitrah, that was revealed to Muhammad. Muslims maintain that previous messages and revelations have been partially changed or corrupted over time and consider the Quran to be the unaltered and the final revelation from Allah. Religious concepts and practices include the five pillars of Islam, which are basic concepts and obligatory acts of worship, and following Islamic law, which touches on virtually every aspect of life and society, encompassing everything from banking and welfare, to warfare and the environment. Islam began its history with an exclusivist attitude toward polytheist religions, but an inclusivist attitude toward monotheists, including Christians and Jews. Believers in the oneness of God were given the status of dhimmi, conferring on them certain rights, including the right to practice their religions openly and not to be pressured to accept Islam. In practice, however, neither the inclusion of Jews and Christians nor militant exclusivism toward "pagans" was always practiced. Trinitarian Christians were accused of idolatry because of their veneration of icons and were also sometimes treated as polytheists because of the doctrines of the Trinity and the Incarnation. Jews generally fared better than Christians under Islamic rule. Jews and Christians are viewed largely favorably as compared to any other religion. The basic attitude of Islam toward other religions remains unchanged today, and certain Islamic nations, such as Saudi Arabia and Iran, are more exclusivistic toward other religions than are others, such as Indonesia and Egypt. Islam does accept sincere Jews, Christians, and Sabians as people "of the Book" along with Muslims.
Judaism
Most Jews believe that the God of Abraham is the one true God. The Jews believe the God of Abraham entered into a covenant with the ancient Israelites, marking them as his Chosen People, giving them a mission to spread the concept of monotheism. Jews do not consider their chosenness to be a mark of superiority to other nations, but a responsibility to be an example of behavior for other nations to emulate.
