The center of the Church is in Salt Lake City, Utah, but there are more than 15 million members living all over the world. About six million of them live in the United States. Four and a half million of them live in the Western United States and 1.8 million live in Utah. It is the second fastest growing church in the United States. It is the fourth largest in the United States. The leader of the Church is called the President of the Church, and members respect him as a prophet. Right now, the President of the Church of Jesus Christ of Latter-Day Saints is Russell M. Nelson. Latter-day Saints believe that God guides their prophet, just like Catholics believe God guides the Pope.
