Mormon reports that, after the ascension of Christ, there were no "Lamanites, nor any manner of-ites;" instead, people were all united.
4 Nephi 1:15-17, The Book of Mormon, The Church of Jesus Christ of Latter-Day Saints, accessed September 29, 2022
15 And it came to pass that there was no contention in the land, because of the love of God which did dwell in the hearts of the people.
16 And there were no envyings, nor strifes, nor tumults, nor whoredoms, nor lyings, nor murders, nor any manner of lasciviousness; and surely there could not be a happier people among all the people who had been created by the hand of God.
17 There were no robbers, nor murderers, neither were there Lamanites, nor any manner of-ites; but they were in one, the children of Christ, and heirs to the kingdom of God.
