We share a good deal with Latter-day Saints: we reject the Trinity and infant baptism, baptise by immersion for the remission of sins, and look for Christ to reign on the earth. Where we differ, the root is authority. God’s word was given once and written down, and it needs no restoration through later prophets.
“Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.”
