What is the difference between Mormonism / The Church of Jesus Christ of Latter-Day Saints and Christianity?

The Church of Jesus Christ of Latter-day Saints (also called LDS or Mormon church) professes to be a Christian church. However, it is important to look at the differences in how each teach. 

Mormonism vs. Christianity

Who is God:

Christianity

God is one.

Church of Jesus Christ of Latter-Day Saints

God (Heavenly Father) is an exalted man with a physical body of flesh and bone. LDS founder Joseph Smith said, “If the veil were rent today, and the great God who holds this world in its orbit, and who upholds all worlds and all things by his power, was to make himself visible-I say, if you were to see him today, you would see him like a man in form” (Teachings of the Prophet Joseph Smith, p. 345). The trinity is denied with the Father, the Son, and the Holy Ghost seen as three separate entities. “The Father has a body of flesh and bones as tangible as man’s; the Son also; but the Holy Ghost has not a body of flesh and bones, but is a personage of Spirit. Were it not so, the Holy Ghost could not dwell in us” (Doctrine and Covenants [D&C] 130:22). 

What is Scripture:

Christianity

The Bible (Old and New Testaments) is a guide for an individual, guided by the Holy Spirit on how to interpret God, the world, what is right and wrong, ect.

Church of Jesus Christ of Latter-Day Saints

Recognizes the LDS Four Standard Works as authoritative. These include the Bible “as far as it is translated correctly” (Not ranked as athoritative as the Book of Mormon ~ Articles of Faith 1:8). It also includes The Book of Mormon (BOM) which Joseph Smith declared is “the most correct of any book on earth, and the keystone of our religion, and a man would get nearer to God by abiding by its precepts, than by any other book” (Teachings of the Prophet Joseph Smith, p. 194).

The church also regards The Doctrine and Covenants (D&C) as Scripture. It “is a collection of modern revelations . . . regarding The Church of Jesus Christ as it has been restored in these last days” (GP, p. 54).

The Pearl of the Great Price (PGP) is the fourth book believed to be inspired.
“It clarifies doctrines and teachings that were lost from the Bible and gives added information concerning the creation of the earth” (GP, p. 54).

The church’s president is regarded as “a seer, a revelator, a translator, and a prophet” (D&C 107:91-92).

Origin of Humanity:

Christianity

Human beings are created in God’s image, meaning they have personal qualities similar to God’s. Every person is a unique, precious being of dignity and worth. (see Gen. 1:26-27)

Church of Jesus Christ of Latter-Day Saints

People are the preexisted spiritual offspring of the Heavenly Father and Mother. “All men and women are . . . literally the sons and daughters of Deity . . . Man, as a spirit, was begotten and born of heavenly parents, and reared to maturity in the eternal mansions of the Father, prior to coming upon the earth in a temporal (physical) body” (Joseph F. Smith, “The Origin of Man,” Improvement Era, Nov. 1909, pp. 78,80, as quoted in GP, p. 11).They are born basically good and are “gods in embryo.” A commonly quoted Mormon aphorism (attributed to fifth LDS president Lorenzo Snow) says “As man is, God once was; as God is, man may become.”

Sin:

Christianity

Human beings are born with a sin nature and willingly chose to sin against God, rejecting His nature and purse life opposed to God. (see Rom. 3:23; 7:14-25; 1 John 1:8-10)

Church of Jesus Christ of Latter-Day Saints

People sin by disobedience to God’s laws. Adam’s fall, a part of Heavenly Father’s plan, caused a loss of immortality, which was necessary for mankind to advance, (see GP, pp. 31-34). As Eve declared according to LDS scripture, “Were it not for our transgression we never should have . . . known good and evil, and the joy of our redemption, and the eternal life which God giveth unto all the obedient”(PGP, Moses 5:11; see also BOM, 2 Nephi 2:22-25). Each person is responsible for his or her own sin.

Salvation:

Christianity

Salvation is release from the guilt and power of sin by acknowledging God’s gift of grace. It is provided through Christ’s atonement and received by personal faith in Christ as Savior and Lord. (see Rom. 3:20; 10:9- 10; Eph. 2:8-10)

Church of Jesus Christ of Latter-Day Saints

Jesus’ atonement provided immortality for all people. Exaltation (godhood) is available only to Mormons through obedience to LDS teachings: faith, baptism, endowments, celestial marriage, and tithing. “Wherefore, as it is written, they are gods, even the sons of God-Wherefore, all things are theirs” (D&C, 76:58-59).

 

These are some of the blessings given to exalted people:

1. They will live eternally in the presence of Heavenly Father and Jesus Christ (see D&C, 76).

2. They will become gods.

3. They will have their righteous family members with them and will be able to have spirit children also. These spirit children will have the same relationship to them as we do to our Heavenly Father. They will be an eternal family.

4. They will receive a fullness of joy.

5. They will have everything that our Heavenly Father and Jesus Christ have – all power, glory, dominion, and knowledge (See GP, p. 302).

Baptism for the dead provides post-mortem salvation for non-Mormons, and is “by immersion performed by a living person for one who is dead. This ordinance is performed in temples” (GP, p. 375). (See also GP, chapters 18-23.)

Church:

Christianity

Christians gather together to hear the Word of God. Everyone is welcome and pious doctrines ignored. 

Church of Jesus Christ of Latter-Day Saints

Asserts that the LDS is the one true church on the face of the earth. Joseph Smith claimed Jesus Christ told him to join none of the existing denominations because “they were all wrong . . . that all their creeds were an abomination in his sight; that those professors were all corrupt” (PGP: Joseph Smith-History 1:19-20). Mormons claim only the LDS possesses the divine authority of the Aaronic and Melchizedek Priesthood as restored by God to Joseph Smith in 1829. (D&C 13; 27:8- 13; 107:1-20; PGP: Joseph Smith-History 1:68-73)

Life after Death

Christianity

Eternal life in heaven with God for those who have trusted in Jesus Christ. (see Matt. 5:12-30; 25:41; Rev. 20-22)

Church of Jesus Christ of Latter-Day Saints

One of three levels of glory:

1. Exaltation in the Celestial Kingdom for faithful Mormons where people may become gods or angels; “Then shall they be gods” (D&C 132:20).

2. Terrestrial Kingdom for righteous non-Mormons; “These are they who are honorable men of the earth, who were blinded by the craftiness of men. These are they who receive of his glory, but not of his fullness” (D&C 76:75-76).

3. Telestial Kingdom for wicked and ungodly (not hell); “These are they who are liars, and sorcerers, and adulterers . . . who suffer the wrath of God on earth”(D&C 76:103-104). (See also D&C 76:57-119; 131:1-4.)
