Missionaries will be called home for WWIII
The Patriarchal blessing is the perfect breeding ground for Mormon urban legends. One of the classic stories claim that a friend of a friend’s roommate at BYU received a blessing stating that he would be called home from his mission to fight in World War III or that he won’t serve a mission because of some global conflict.
There has never been reliable documented evidence to back up this claim. These stories have also been around for years.
