PUBLIC AFFAIRS: “On the issue of a Constitutional amendment prohibiting same-gender marriage, there are some Latter-day Saints who are opposed to same-gender marriage, but who are not in favor of addressing this through a Constitutional amendment. Why did the Church feel that it had to step in that direction?”
DALLIN H. OAKS: “There are people who oppose a federal Constitutional amendment because they think that the law of family should be made by the states. I can see a legitimate argument there. I think it’s mistaken, however, because the federal government, through the decisions of life-tenured federal judges, has already taken over that area. This Constitutional amendment is a defensive measure against those who would ignore the will of the states appropriately expressed and require, as a matter of federal law, the recognition of same-gender marriages — or the invalidation of state laws that require that marriage be between a man and a woman. In summary, the First Presidency has come out for an amendment (which may or may not be adopted) in support of the teaching function of the law. Such an amendment would be a very important expression of public policy, which would feed into or should feed into the decisions of judges across the length and breadth of the land.”
