Religious perspectives

Religions have had differing views about love and sexual relations between people of the same sex. A large proportion of the Abrahamic sects view sexual relationships outside of a heterosexual marriage, including sex between same-sex partners, negatively, though there are groups within each faith that disagree with orthodox positions and challenge their doctrinal authority. The Bible can also be understood literally, as homosexuality is viewed as sinful and problematic. Opposition to homosexual behavior ranges from quietly discouraging displays and activities to those who explicitly forbid same-sex sexual practices among adherents and actively opposing social acceptance of homosexual relationships. Support of homosexual behavior is reflected in the acceptance of sexually heterodox individuals in all functions of the church, and the sanctification of same-sex unions. Furthermore, liberal Christians may not consider same-sex relations to be sinful. Jews, Mainline Protestants and the religiously unaffiliated tend to be more supportive of gay and lesbian relationships.

Some churches have changed their doctrine to accommodate same-sex relationships. Reform Judaism, the largest branch of Judaism outside Israel has begun to facilitate religious same-sex marriages for adherents in their synagogues. Jewish Theological Seminary, considered to be the flagship institution of Conservative Judaism, decided in March 2007 to begin accepting applicants in same-sex relationships, after scholars who guide the movement lifted the ban on ordaining people in same-sex relationships. In 2005, the United Church of Christ became the largest Christian denomination in the United States to formally endorse same-sex marriage.

On the other hand, the Anglican Communion encountered discord that caused a rift between the African (except Southern Africa) and Asian Anglican churches on the one hand and North American churches on the other when American and Canadian churches openly ordained clergy in same-sex relations and began same-sex unions. Other churches such as the Methodist Church had experienced trials of clergy in same-sex relations who some claimed were a violation of religious principles resulting in mixed verdicts dependent on geography.

Some religious groups have even promoted boycotts of corporations whose policies support same-sex relations. In early 2005, the American Family Association threatened a boycott of Ford products to protest Ford's perceived support of "the homosexual agenda and homosexual marriage".
