Bahá'í sexual ethics confine sexual relations to marriage between a man and a woman. The institutions do not perform same-sex marriages, and Bahá'ís are expected to observe the teaching in their own lives. Simultaneously the faith requires opposition to prejudice of every kind, and Bahá'í institutions have stated repeatedly that homosexual people must be treated with respect and love and that no one is to be judged or excluded on the basis of orientation, that no Bahá'í is entitled to enquire into another's private life, and that the community must not participate in hostility toward gay people. The Universal House of Justice has stated that the teaching on the nature of marriage derives from scripture and is not within the authority of the institutions to alter, while also noting that Bahá'ís may hold and express personal views. The result is a position the community itself finds uncomfortable, and it is the subject of continuing internal discussion, some public, particularly in North America and Europe.
