MORMONISM
Redemption and Salvation
We believe that through the atonement of Christ, all mankind may be saved, by obedience to the laws and ordinances of the gospel (AF, 3).
The first principles and ordinances of the gospel are: Faith on the Lord Jesus Christ; repentance; baptism by immersion for the remission of sins; and laying on of hands for the gift of the Holy Ghost (AF, 4).
Even the unbeliever, the heathen, and the child who dies before reaching the years of discretion, all are redeemed by the Savior's self-sacrifice from the individual consequences of the Fall (Talmage, p. 58).
Included are "beasts, fowls of the air, and fishes of the sea" (DC, 29:23-25).
The resurrection of the body (of every living thing) is one of the victories achieved by Christ through His atoning sacrifice (Talmage, p. 58).
They who believe not your words, and are not baptized in water in my name, for the remission of their sins...shall be damned (DC, 84:74).
Baptism is...the very gateway into the kingdom of heaven, an indispensable step in our salvation and exaltation (Bennett, Why I Am a Mormon, p. 124).
Baptism by proxy for the dead is a major activity. "The Saints are...redeeming their (unbaptized) dead from the grasp of Satan" (Morgan, Plan of Salvation, p. 8).
Celestial marriage is the gate to an exaltation in the highest heaven within the celestial world (McConkie, MD, p. 118).
Those who attain the highest sphere, the Celestial, will "have spirit children in the resurrection, in relation to which offspring they stand in the same position that God our Father stands to us" (MD, p. 257).
The second sphere, the Terrestrial, will be inhabited by "accountable persons who die without law" or who "did not accept the gospel" or with LDS who "were not valiant" (MD, p. 784).
