If their name was the Reorganized Church of Jesus Christ of Latter Day Saints and they recently changed their name to The Community of Christ, isn't it a little disingenuous to say that they are not related to The Church of Jesus Christ of Latter Day Saints? And in fact, wasn't the founder in 1860 Joseph Smith, Jr. the son of the founder of the Utah Church?
I don't understand your point,if one breaks or falls aways they no longer are a part of!
The Lutherns broke/fell away from the Catholic Church they are no longer a part of!
If you are talking about the misuse of the word related sorry!
Today CC has nothing in come not even the name!
