Such a suggestion would be impossible, given the Federal Government's long history of making pronouncements regarding marriage—for example, conditioning Utah's entry into the Union upon its prohibition of polygamy. See Act of July 16, 1894, ch. 138, § 3, 28 Stat. 108 (“The constitution [of Utah]” must provide “perfect toleration of religious sentiment,” “ Provided, That polygamous or plural marriages are forever prohibited”).
