I recently took a peak at a blog (Saints' Herald) from some of our "cousins" at the Community of Christ (formerly the RLDS Church). There was one post that I found particularly interesting: The Name of The Church. It was well researched and well written. It speaks to both the name of the early Church we all share in common, as well as the changes over time as they branch off from there. I'm sure Latter-day Saints will find it interesting and worthwhile.
