From Wikipedia, the free encyclopediaThe cross of the war memorial and a menorah for Hanukkah coexist in Oxford. Religious toleration is the condition of accepting or permitting others' religious beliefs and practices which disagree with one's own.
In a country with a state religion, toleration means that the government permits religious practices of other sects besides the state religion, and does not persecute believers in other faiths. Historically, toleration has been a contentious issue within many religions as well as between one religion and another. At issue is not merely whether other faiths should be permitted, but also whether a ruler who is a believer may practice or permit tolerance. In the Middle Ages, toleration of Judaism was a contentious issue throughout Christendom. Today, there are concerns about toleration of Christianity in Islamic states (see also dhimmi).
Proselytism can be a contentious issue; it can be regarded as an offence against the validity of others' religions, or as an expression of one's own faith.
 The element of objection
For individuals, religious toleration generally means an attitude of acceptance towards other people's religions. It does not mean that one views other religions as equally true; merely that others have the right to hold and practice their beliefs. This element of objection is important. People, who take these matters seriously, often experience distress when they are confronted with religious beliefs that they regard as idolatrous, superstitious, heretical or schismatic. Even in the western world, this is not only a historic issue, as in the Christian debate on persecution and toleration.
Contemporary authors such as Sam Harris, Richard Dawkins, Christopher Hitchens and Daniel C. Dennett have all written about the potential social hazards of allowing religious beliefs to go unchallenged. In The End of Faith, Sam Harris notes that we are unwilling, as a society, to tolerate unjustified beliefs in, for example, architecture. He asserts that we should be similarly unwilling to tolerate unjustified beliefs about morality, spirituality, politics, and the origin of humanity. In his preface to The God Delusion, Richard Dawkins says, "If this book works as I intend, religious readers who open it will be atheists when they put it down."
 Civil and ecclesiastical tolerance
Generally, when people speak of religious tolerance, the mean civil tolerance - "the policy of the state towards religious dissent". In contrast to this, ecclesiastical tolerance is concerned with the degree of diversity tolerated within a particular church.
