From the Amicus Brief of Major Religious Organizations, Apr 2015
Recognizing a new right to same-sex marriage would harm religious liberty. That harm is avoidable because neither the Constitution nor this Court’s precedents dictates a single definition of marriage for the Nation. Preserving religious liberty is a compelling reason not to give the Fourteenth Amendment a novel reading that would require every State to license and recognize marriage between persons of the same sex. At a minimum, the Court should carefully consider how a ruling mandating same-sex marriage would adversely affect religious liberty.Also see the news release of the LDS church, "Religious Freedom and Fairness for All"
Will this become a question for future Presidential candidates?
Do you support a constitutional amendment restoring natural marriage? If not, then what exactly will you do to protect my religious freedom? If nothing, why should I support you? ("If the Supreme Court Imposes Same Sex Marriage, You Could Lose Your Church", John Zmirak, Apr 30, 2015)
