“The very fundamental principle of freedom is absolutely essential for the gospel of Jesus Christ to prosper. And so from the very beginning, the times of the Prophet Joseph Smith and the early founders of the Church, that principle of sustaining the constitution – under which is religious freedom giving people the agency and the freedom to make their own choices – this is a very very important principle and has been taught from the very beginning in the history of our Church.”
