When Martin Luther King Jr. came to Detroit in June 1963 and led the 120,000-strong Great March on Detroit, Romney designated the occasion Freedom March Day in Michigan, and sent state senator Stanley Thayer to march with King as his emissary, but did not attend himself because it was on Sunday. Romney did participate in a much smaller march protesting housing discrimination the following Saturday in Grosse Pointe, after King had left. Romney's advocacy of civil rights brought him criticism from some in his own church; in January 1964, Quorum of the Twelve Apostles member Delbert L. Stapley wrote him that a proposed civil rights bill was "vicious legislation" and telling him that "the Lord had placed the curse upon the Negro" and men should not seek its removal. Romney refused to change his position and increased his efforts towards civil rights. Regarding the church policy itself, Romney was among those liberal Mormons who hoped the church leadership would revise the theological interpretation that underlay it, but Romney did not believe in publicly criticizing the church, subsequently saying that fellow Mormon Stewart Udall's 1967 published denunciation of the policy "cannot serve any useful religious purpose".
