Buddhism originated in the Indian sub-continent approximately 500 years before the introduction of Christianity with the teachings of Siddhārtha Gautama. In Buddhist dogma, the soul is in an almost endless cycle of birth and rebirth and the material world is largely illusory. The termination of this cycle of rebirth is achieved by the cessation of desire which is the source of suffering. Because Buddhism does not have a concept of a creator deity it is generally not rational for a Buddhist to be offended by the differing dogma of Christians or Muslims. While Christianity and Islam are essentially incompatible with the core tenets of Buddhist thought, they are—from the view of the obeisant Buddhist—tolerable as there is no commandment that exists to be broken.
Christianity originated in Palestine approximately two thousand years ago with the revelation of the Jewish carpenter Jesus Christ as the prophesied son of God. It teaches a personal relationship with a creator deity and Christians are encouraged to be active participants in a coming salvation that will occur in an end times. At the same time, however, the New Testament also teaches a form of religious tolerance (2 Corinthians 10:12):
We do not dare to classify or compare ourselves with some who commend themselves. When they measure themselves by themselves and compare themselves with themselves, they are not wise.
Christians may view Buddhists and Muslims as persons needing salvation by the acceptance of Jesus Christ.
Islam originated in fifth century Arabia with the teachings of Muhammad. In Islamic doctrine, Jesus Christ was a prophet of God, but not a divine being and Christians are confused followers of God who should be offered the opportunity of conversion but, as "people of the book," must be tolerated failing that (Qur'an 3:64-71):
O people of the Book! Come to common terms as between us and you: that we worship none but Allah; that we associate no partners with Him; that we erect not from among ourselves Lords and patrons other than Allah." If then they turn back say: "Bear witness that we (at least) are Muslims (bowing to Allah's will)."
Buddhism, however, is viewed with greater skepticism in Islam because it rejects the notion of a unitary, monotheistic God and such rejection is a blasphemy.
