Mormonism 101: Why do Mormons call each other “Brother” and “Sister”?
The terms Brother and Sister, and even Elder, are honorifics.” Honorifics are terms or titles used to address a person. The titles Mrs., Mr. and Dr. are honorifics as are Sultan and and Africanus. For centuries, up to a few decades ago, it was common to address people within your church in this way, as brother and sister. Mormons have kept up this tradition.
Mormons are so accustomed to this that we often find it difficult to address other people outside the church as Mr. and Mrs. LDS ladies discussing party assignments outside the church….say at a PTA meeting may sound like this. “We have assigned Sister…, I mean Mrs. Smith, the cupcakes. And Sister, I mean Ms. Dunkin the punch and Sister… I mean Tina the invitations.”
It’s not as if you don’t deserve to be called Brother and Sister , we correct ourselves so we don’t offend.
