The pre-eminent leader of the Mormon church Russell Nelson announced that in future everyone should stop using the terms “Mormon Church”, “Mormons” and “Mormonism” when referring to the church or its members. Instead, the church should be called “The Church of Jesus Christ of Latter-day Saints” and the members as “members of The Church of Jesus Christ of Latter-day Saints” or “Latter-day Saints”. He said that even the abbreviation LDS should not be used. The church’s style guide has more.
I think Nelson is going to have a tough fight on this front. It would be like the Catholic Church asking to be referred to as the Roman Catholic Church and its members as Roman Catholics in future. Once people are used to calling an institution and its members something, it will be hard to change the usage.
Nelson said that his god had spoken to him and told him to tell the world all this. It would have been more likely to happen if his god had spoken directly to all of us. But he never does.
