Brighamites: Book of Mormon = keystone Temple Endowment for all Racism BoA = Egyptian No JST Deacons = 12 years old Jesus Smith is our savior Polygamy is a STILL a Gospel Principle
(old, not CoC)Reorganized Josephites: Book of Mormon is a companion to New Testament Temple Endowment for some not all Not as racist (Lamanites still cursed?) BoA = inspired from Egyptian JST Deacons = men Jesus Christ is our savior Polygamy never was a Gospel Principle
I think this is the route LDS Inc. will take. It won't got as far as Community of Christ but will appeal to super conservative restorationists.
Oh, and current temples would be renovated and rededicated to be more public on the Old Nauvoo floor plan - meeting rooms and offices with "upper rooms" for endowment and what we know today as "temple work."
