There is but one Lord, one faith, and one system of salvation. Those of all nations, kindreds, and tongues, those of all ages of earth’s history, are redeemed by the same atonement, must profess the same Savior, and comply with the same laws and ordinances if they are to be saved. It is because of this very principle that the doctrines of the Book of Mormon are timeless in value. See commentary on Mosiah 5:7.
