1 U.S.C. § 7: Marriage

For the purposes of any Federal law, rule, or regulation in which marital status is a factor, an individual shall be considered married if that individual’s marriage is between 2 individuals and is valid in the State where the marriage was entered into or, in the case of a marriage entered into outside any State, if the marriage is between 2 individuals and is valid in the place where entered into and the marriage could have been entered into in a State. In this section, the term “State” means a State, the District of Columbia, the Commonwealth of Puerto Rico, or any other territory or possession of the United States. For purposes of subsection (a), in determining whether a marriage is valid in a State or the place where entered into, if outside of any State, only the law of the jurisdiction applicable at the time the marriage was entered into may be considered. No union is more profound than marriage, for it embodies the highest ideals of love, fidelity, devotion, sacrifice, and family. Diverse beliefs about the role of gender in marriage are held by reasonable and sincere people based on decent and honorable religious or philosophical premises. Therefore, Congress affirms that such people and their diverse beliefs are due proper respect. Millions of people, including interracial and same-sex couples, have entered into marriages and have enjoyed the rights and privileges associated with marriage. Couples joining in marriage deserve to have the dignity, stability, and ongoing protection that marriage affords to families and children.” Nothing in this Act [see Short Title of 2022 Amendment note set out under section 1 of this title ], or any amendment made by this Act, shall be construed to diminish or abrogate a religious liberty or conscience protection otherwise available to an individual or organization under the Constitution of the United States or Federal law. Consistent with the First Amendment to the Constitution, nonprofit religious organizations, including churches, mosques, synagogues, temples, nondenominational ministries, interdenominational and ecumenical organizations, mission organizations, faith-based social agencies, religious educational institutions, and nonprofit entities whose principal purpose is the study, practice, or advancement of religion, and any employee of such an organization, shall not be required to provide services, accommodations, advantages, facilities, goods, or privileges for the solemnization or celebration of a marriage. Any refusal under this subsection to provide such services, accommodations, advantages, facilities, goods, or privileges shall not create any civil claim or cause of action.” Nothing in this Act [see Short Title of 2022 Amendment note set out under section 1 of this title ], or any amendment made by this Act, shall be construed to deny or alter any benefit, status, or right of an otherwise eligible entity or person which does not arise from a marriage, including tax-exempt status, tax treatment, educational funding, or a grant, contract, agreement, guarantee, loan, scholarship, license, certification, accreditation, claim, or defense. Nothing in this Act, or any amendment made by this Act, shall be construed to require or authorize Federal recognition of marriages between more than 2 individuals.”
