Currently in the U.S. are churches forced to marry all couples, including same-sex couples?

In the U.S., churches and clergy can generally choose which couples they will marry, and civil law does not force them to perform ceremonies that violate their religious doctrine.

Civil vs. religious marriage

• Civil marriage is what the state controls: issuing licenses, recognition, benefits, and constitutional rights; Obergefell requires governments to license and recognize same‑sex marriages on equal terms.​
• Religious marriage is governed by the internal rules of each faith community; Obergefell and similar laws do not require any church to change its doctrine or religious marriage practices.

Clergy discretion

• The First Amendment protects churches, synagogues, mosques, and similar bodies in deciding which marriages they recognize and celebrate, including declining to marry couples whose situation conflicts with their beliefs (such as same‑sex couples, interfaith couples, or divorcees without an annulment in Catholic practice).
• Legal analyses after Obergefell note that there is “no significant risk” that pastors or churches can be compelled to perform same‑sex weddings; the decision binds governments, not religious officiants.

Public accommodations vs. houses of worship

• Anti‑discrimination laws mainly apply to “public accommodations” (businesses and services open to the general public), not to houses of worship conducting religious rites for their members.
• If a religious institution runs services that are truly open to the public (for example, a commercial event venue unrelated to worship), that specific service can sometimes be treated like a public accommodation, but ordinary sacramental marriage rites inside a church are treated as religious activity with broad autonomy.
