It’s the biggest question of all. Here’s what we mean by “true,” what to weigh, and the one test that settles it.
Latter-day Saints believe The Church of Jesus Christ of Latter-day Saints is Christ’s restored Church, “the only true and living church upon the face of the whole earth” (D&C 1:30). “True” means it has His full doctrine and priesthood authority; “living” means it receives ongoing revelation. The Bible foretold a falling away (2 Thessalonians 2:3) and a “restitution of all things” (Acts 3:21). The way to know isn’t argument alone: Jesus said, “If any man will do his will, he shall know of the doctrine” (John 7:17).
The short answerLatter-day Saints believe it is, and invite you to find out
The Lord described the Church in 1831 as “the only true and living church upon the face of the whole earth, with which I, the Lord, am well pleased, speaking unto the church collectively and not individually” (D&C 1:30). “True” means it teaches Christ’s full doctrine and holds His authority. “Living” means it receives ongoing revelation through living prophets.
That isn’t a claim that other churches have no truth or that their members are less good. It’s a claim about authority and the fulness of the gospel. And it comes with an invitation, not a demand: Jesus said, “If any man will do his will, he shall know of the doctrine, whether it be of God” (John 7:17).

What the Bible foretoldA falling away, then a restoration
If the Church Christ founded was still on earth in its fulness, no restoration would be needed. But the New Testament warned of a falling away. Paul said “that day shall not come, except there come a falling away first” (2 Thessalonians 2:3), and told the Ephesian elders, “after my departing shall grievous wolves enter in among you … Also of your own selves shall men arise, speaking perverse things” (Acts 20:29–30). Amos foresaw “a famine … of hearing the words of the Lord” (Amos 8:11–12).
Then Peter promised “the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets” before Christ returns (Acts 3:19–21). Daniel foresaw that in the last days “shall the God of heaven set up a kingdom, which shall never be destroyed” (Daniel 2:44). Latter-day Saints believe that restoration began in 1820 and that the kingdom is the Church. See The Great Apostasy in the New Testament’s Own Words.
Marks of Christ’s ChurchName, organization, authority
The risen Christ gave the Nephites a simple test: “how be it my church save it be called in my name? … if it be called in my name then it is my church, if it so be that they are built upon my gospel” (3 Nephi 27:8). The Church bears His name: The Church of Jesus Christ of Latter-day Saints.
Christ’s Church is “built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone” (Ephesians 2:19–20). Latter-day Saints “believe in the same organization that existed in the Primitive Church, namely, apostles, prophets, pastors, teachers, evangelists” (Articles of Faith 1:6). And authority must come from God: “no man taketh this honour unto himself, but he that is called of God, as was Aaron” (Hebrews 5:4). That authority was restored by John the Baptist and by Peter, James and John. See Priesthood Authority: Korah, Uzziah and Hebrews 5:4.
Restored doctrineTruths the creeds lost
The Restoration brought back plain truths about God and His children. God the Father and Jesus Christ are distinct, glorified Persons (Joseph Smith—History 1:17; D&C 130:22). We lived with God before birth. Families can be sealed forever. Those who die without the gospel will hear it. And through Christ, God’s children can become like their Father: Joseph Smith taught that God “was once as we are now, and is an exalted man,” that the Father Himself had a Father, and that His faithful children will grow “from exaltation to exaltation” to create worlds without number, always as His children (History of the Church 6:305–306). See Was God Once a Man?.
The evidenceStart with the Book of Mormon
The keystone is the Book of Mormon. If it’s true, Joseph Smith was a prophet and the Church he restored is true. If it isn’t, nothing else matters. That’s why the evidence matters: the witnesses, the complexity, the Hebrew poetry, the names and places that later research confirmed. We collect it at Is the Book of Mormon True? and The Best Book of Mormon Evidences.
Jesus also said, “by their fruits ye shall know them” (Matthew 7:20). Look at the lives the Church produces: missionaries, a lay ministry, care for the poor, families trying to follow Christ. Judge the tree by its fruit, not by its critics.
How to knowThe test only God can answer
Evidence can open the door, but the scriptures say the answer comes from God by the Holy Ghost. The Book of Mormon promises: “ask God, the Eternal Father, in the name of Christ, if these things are not true; and if ye shall ask with a sincere heart, with real intent, having faith in Christ, he will manifest the truth of it unto you, by the power of the Holy Ghost” (Moroni 10:4–5).
The Lord described how that answer feels: “I will tell you in your mind and in your heart, by the Holy Ghost, which shall come upon you and which shall dwell in your heart. Now, behold, this is the spirit of revelation” (D&C 8:2–3). Read, live it, and ask. That’s the whole test.
Check the premiseThe presuppositions baked into the question
Before this question can be answered fairly, the person asking has to justify a few assumptions packed inside it:
- That “only true church” means only Latter-day Saints are good or will be saved. The Lord was “speaking unto the church collectively and not individually” (D&C 1:30), and the gospel will be preached to all, living and dead.
- That the original Church continued unbroken. The New Testament foretold “a falling away first” (2 Thessalonians 2:3) and a later “restitution of all things” (Acts 3:21).
- That you have to settle it by arguments alone. Jesus said you can know by doing God’s will (John 7:17).
- That other churches have nothing true. Latter-day Saints honor the truth in other faiths and invite people to add the restored fulness to it.
FAQQuick answers
Is the LDS Church true?
Latter-day Saints believe it is Christ’s restored Church, with His full doctrine and priesthood authority (D&C 1:30). They invite everyone to find out for themselves by reading the Book of Mormon and asking God (Moroni 10:4–5).
What does “only true church” mean?
That the Church has the fulness of Christ’s gospel and His authority, not that other people are bad or that other churches have no truth.
How can I know if the Church is true?
Study the Book of Mormon, live its teachings, and pray with real intent. The Holy Ghost will answer in your mind and heart (D&C 8:2–3; John 7:17).
Did the Bible predict a restoration?
Yes. Peter spoke of “the times of restitution of all things” before Christ’s return (Acts 3:21), and Daniel saw a kingdom set up by God that would never be destroyed (Daniel 2:44).
What if I can’t get an answer?
Keep studying, serving and praying. Answers often come over time, “line upon line” (2 Nephi 28:30).
Does the Church claim priesthood authority from God?
Yes. Joseph Smith and Oliver Cowdery said John the Baptist laid hands on them in 1829, saying, “Upon you my fellow servants, in the name of Messiah, I confer the Priesthood of Aaron” (Joseph Smith—History 1:69).

Yes. “If there is anything virtuous, lovely, or of good report or praiseworthy, we seek after these things” (Articles of Faith 1:13).
What is the Great Apostasy?
The loss of Christ’s authority and many plain truths after the apostles died, which Paul foretold: “that day shall not come, except there come a falling away first” (2 Thessalonians 2:3).
