Most religious groups in the U.S. now support same-sex marriage, including overwhelming majorities of Unitarians (97%), Buddhists (80%), the religiously unaffiliated (80%), Jewish Americans (77%), and Hindus (75%). Roughly two-thirds of white mainline Protestants (67%), white Catholics (66%), Orthodox Christians (66%), and Hispanic Catholics (65%) also favor same-sex marriage. A slim majority of Muslims (51%) favor same-sex marriage, but only 34% are opposed; 15% offer no opinion on this issue.

Opposition to same-sex marriage is now confined to a few of the most conservative Christian religious traditions. Only about one-third (34%) of white evangelical Protestants support same-sex marriage today, while nearly six in ten (58%) are opposed, including 30% who are strongly opposed. And just 40% of Mormons support same-sex marriage, compared to 53% who are opposed. Jehovah’s Witnesses, a racially mixed religious group, are the exception. Just 13% support the policy, compared to 63% who oppose it. However, nearly one-quarter (24%) of Jehovah’s Witnesses express no opinion on this issue. Nevertheless, even those religious groups most opposed to same-sex marriage have become more accepting of it over the last five years.
