It looks like members of The Church of Jesus Christ of Latter-day Saints will be soon saying farewell to their various nicknames. That seems to be the intent of the bold new announcement from President Russell M. Nelson.

Announcement from President Nelson
Here's what President Nelson says, as published by Mormon Newsroom today:
The Lord has impressed upon my mind the importance of the name He has revealed for His Church, even The Church of Jesus
Still, it would be good for us to try to make the requested switch. (And certainly, if the members don't try, no one else will bother, but they'll also learn that we ignore the prophet when we consider it [insert adjective here].)
