Quick Summary
This article compares Christianity vs Mormons (Latter-day Saints) by examining key differences in God, Jesus, salvation, authority, and Scripture.
While both use Christian language and affirm belief in Jesus Christ, their teachings differ in foundational ways. Understanding these differences helps clarify what each system truly teaches.
Christianity vs Mormons: Scripture Authority
Latter-day Saint doctrine is built on four primary sources of scripture:
The Bible (KJV preferred)
The Book of Mormon
Doctrine and Covenants
Pearl of Great Price
The Bible is accepted “as far as it is translated correctly,” meaning it is viewed as incomplete or altered.
Christian belief: The Bible alone is the complete, inspired, and sufficient Word of God (2 Timothy 3:16-17; Jude 1:3).
Christianity vs Mormons: Core Beliefs
The 13 Articles of Faith summarize LDS beliefs, including:
God the Father, Jesus Christ, and the Holy Ghost as separate beings
Salvation through Christ plus obedience
Baptism and ordinances as essential
Ongoing revelation through prophets
These teachings introduce key differences from historic Christianity.
Christianity vs Mormons: God and the Godhead
LDS Teaching: The Father, Son, and Holy Ghost are three separate beings. God has a physical body, and humans can become like God.
Christian Belief: One eternal God in three Persons, unchanging and unique (Deuteronomy 6:4; Isaiah 43:10; John 4:24).
Christianity vs Mormons: Jesus Christ
LDS Teaching: Jesus is the firstborn spirit child of God and the spirit brother of humanity.
Christian Belief: Jesus is eternal, uncreated, and fully God - the Creator of all things (John 1:1-3; Colossians 1:16-17).
Christianity vs Mormons: Salvation
LDS Teaching: Grace makes salvation possible, but exaltation requires obedience, ordinances, and effort.
Christian Belief: Salvation is by grace alone through faith alone - not by works (Ephesians 2:8-9; Romans 3:28).
Christianity vs Mormons: Human Nature
LDS Teaching: The Fall was necessary; humans are not born guilty.
Christian Belief: Humanity is fallen and spiritually dead apart from Christ (Romans 5:12; Ephesians 2:1-3).
Christianity vs Mormons: Afterlife
LDS Teaching: Three degrees of glory and continued progression.
Christian Belief: Final judgment leading to eternal life or separation from God (Hebrews 9:27; Matthew 25:46).
Christianity vs Mormons: Authority
LDS Teaching: A Great Apostasy required restoration through Joseph Smith and ongoing prophets.
Christian Belief: The Gospel has been preserved, and Scripture is complete (Galatians 1:8-9; Jude 1:3).
Christianity vs Mormons: Key Differences
God
LDS: Multiple beings, progression to godhood
Christianity: One eternal, unchanging God
Jesus
LDS: Created being
Christianity: Eternal Creator
Salvation
LDS: Grace + works
Christianity: Grace alone
Scripture
LDS: Multiple books + revelation
Christianity: Bible alone
Apologetic Insight
The core issue in Christianity vs Mormons is authority and the nature of God.
If God is eternal and unchanging, then any system that redefines Him or adds new revelation must be tested against what has already been revealed (Malachi 3:6; Hebrews 13:8; Galatians 1:8).
This raises a crucial question:
Was the Gospel lost and restored - or preserved as originally given?
Takeaway
Christianity vs Mormons is not simply a difference in terminology, but a difference in foundation.
Historic Christianity teaches a finished Gospel centered on the eternal nature of God and salvation by grace alone. Mormon theology introduces additional authority, progression, and required works that reshape that message.
Understanding these differences allows for clear, respectful conversations that point back to the sufficiency of Christ and the authority of Scripture.
