Sharing Your Faith with Latter-day Saints

By Sandra Tanner

One of the most important factors in sharing your faith with a Mormon (officially known as the Church of Jesus Christ of Latter-day Saints) is your sincere friendship. Usually former LDS tell me that they had a close friend that talked to them about the Lord. This friend acted as a bridge between Mormon assumptions and explaining what the Bible actually says.

Usually Mormons will already view themselves as Christians and will accept you as one as well. However, they would see you as only having one fourth of the gospel while they have the whole package. Your faith in Christ, according to them, assures you of a place in heaven. However, in order to go to the highest part of heaven, the Celestial Kingdom (godhood, exaltation), you would need to have a Mormon baptism and a Mormon temple marriage. (See Mormons Hope to Become Gods of Their Own Worlds.) They believe that if you don't join the LDS Church during this life you will be given a chance to accept it during the millennium.

Remember that they view you as the one with the defective belief system. You have only the Bible (which accounts for your "limited" understanding) while they have additional light from their other scriptures, the Book of Mormon, the Doctrine and Covenants and the Pearl of Great Price. Beyond this, they also have the teachings of their prophets.

Keep in mind that we are part of a process. Paul wrote: "I have planted, Apollos watered; but God gave the increase." (1 Cor. 3:6) It may take several encounters with various Christians before the Mormon will seriously start re-evaluating his/her beliefs. Pray that God will continue to bring Christians into the Mormon's life.

Terminology Differences

It is important to learn how Christian terms have been redefined by Mormonism. (See Terminology Differences.) If you went as a missionary to China you would learn their language and something about their customs. We should do the same with those embracing the LDS system. Don't assume the Mormon uses Christian terms the same as you do. Their definitions of God, salvation, eternal life, heaven, etc. are very different.


When opportunities arise for you to talk with Mormons about their beliefs, remember to show them the same respect and courtesy you would expect from them. Be sure to display confidence (not arrogance) in what you discuss. Mormons tend to interpret any timidity as evidence that you do not speak with the authority of God.

Since Mormons tend to feel any challenge to their church is a form of persecution we must be careful how we approach them so that it will not reinforce this perception.

Joseph Smith claimed in his first vision which is printed at the back of their Pearl of Great Price, that God informed him all other churches were "wrong" and that "all their creeds were an abomination in his sight." Since Smith was the one who first attacked all other churches, we are simply responding to his charges. Merely comparing belief systems is not "persecution."

Importance of the Book of Mormon?

Mormons will often ask people if they have read the Book of Mormon and prayed about it. They assume that if someone believed it he would accept the rest of Mormonism. Here are a few questions to ask:

This gives us a chance to talk about the value of the Book of Mormon, as opposed to the Bible. Ask them:

Which Bible?

The Book of Mormon declares that the Bible has been deliberately altered (see 1 Nephi 13:26-28). Mormons will often point to all the different translations of the Bible as proof that it has been changed. You can ask them something like:

Mormons will often claim the Bible is incomplete, that various books have been left out of our current Bible.

Remind them that even though we don't have all of the words of Jesus, John assured us that we have all that we need to know about gaining eternal life (see John 20:30-31). Also, Jesus promised "Heaven and earth shall pass away, but my words shall not pass away." (Matthew 24:35)

If Mormonism is a restoration of original Christianity they would need to demonstrate that LDS doctrines were originally in the Bible but later deleted. However, there is no manuscript evidence of revisions of the New Testament that eliminated cardinal doctrines. Also, the scripture quotes in the writings of the early church fathers show that there were no doctrinal changes. A good book on the reliability of the Bible is The New Testament Documents: Are They Reliable?, by F.F. Bruce.

Total Apostasy?

Mormonism asserts that in Smith's first vision he was told that there had been a total apostasy of the Christian church and that he was to be God's instrument in restoring it to the earth. While the Bible speaks of people falling away from the truth, it never indicates that there would be a total apostasy. Mormons often misuse 1 Timothy 4:1 which says that "in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils." Notice that the verse merely indicates "some" would depart from the faith, not that there would be a total apostasy. You might ask your friend something like this:

Another problem with the LDS claim of a total apostasy is their own teaching that John, one of Christ's twelve apostles, did not die (see D&C 7:1-3) but was to remain on the earth to "prophesy before nations." Besides John, three of the twelve disciples in the Book of Mormon were granted their desire to remain on earth, to "bring the souls of men unto me," until Christ's return (Book of Mormon, 3 Nephi 28:6-9).

Mormonism also teaches that the true church will have the same structure as Christ instituted. Thus they argue that the true church will have twelve apostles at its head. However, the Mormons do not conform to their own standard as they have three apostles in their First Presidency as well as their twelve, thus making fifteen apostles at the head of their church. Also, Deacons were to be mature men, not twelve-year-old boys (see 1 Tim. 3:8-12).

True Church?

Mormons will often say that the Christian world is too divided to have the truth. Yet there have been over 100 different churches claiming Joseph Smith as their founder. (See the book Divergent Paths of the Restoration.) Many of them have totally different beliefs from the others. Obviously, LDS scriptures did not solve the problem of division.

However, the Christian looks to such verses as Matt. 18:20 where Christ promised that where two or three are gathered in His name, He is in the midst of them. The Mormon does not understand the Christian concept of all believers constituting the church. In Eph. 2:20-22 Paul points out that Christians "are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief cornerstone; in whom all the building fitly framed together groweth unto an holy temple in the Lord: in whom ye also are builded together for an habitation of God through the Spirit." Thus the question is not whether you are member of the right denomination but are you trusting Christ's atonement to make you right with God?

A Prophet?

Another area for discussion is the need for a prophet. You might ask the Mormon:

Christians hold their ministers accountable to the Bible. (See Galatians 1:7-12 and 1 John 4:1) The early Christians compared Paul's teachings with the Old Testament in Acts 17:11-12. What is the standard for Mormons?

They may counter with something like: "God has promised he will never let the prophet lead us astray." Then why is there provision made in the Doctrine and Covenants Sec. 107:81-83 to replace a fallen prophet? Jesus warned about false prophets in Matt. 24:11 and 24.

Mormons point to Amos 3:7 to prove that God will always have a prophet leading the church. However, this is taking the verse out of context. God promised that he would not send judgment without giving a warning first through a prophet.

If you bring up a doctrinal issue like Brigham Young's Adam-God doctrine they will often counter that that was Young's personal idea and not official doctrine even though he taught it from the pulpit. Then what constitutes "official doctrine"? The Mormon will usually counter that doctrine must be voted on by the church and canonized. Doesn't this establish that one of their prophets could give a false revelation? Then couldn't he lead the people astray?

Another question is why does the Doctrine and Covenants only have four sections by prophets other than Joseph Smith? Why has no revelation been added since 1978? Is God no longer giving revelation to their president as he did in the beginning?

If a Mormon says that their prophets still get revelations, ask where they are printed. Why don't they canonize them? Are they approaching a closed canon concept?

Need More Than Atonement?

Mormons will often say, "Why can't you accept us as Christians? We believe in Jesus as our savior." However, there are problems with both their definition of "saved" and their concept of Jesus.

Mormonism limits the result of the Fall, saying that it brought mortality but not a sinful nature as man is supposed to be a god in embryo. They limit the atonement, saying it brought resurrection (or immortality) to all, but to go on to "eternal life" or "exaltation" one must be a faithful Mormon thus adding works to grace. They believe they commit sin but don't understand man's basic sin-nature.

They make a distinction between being "saved" (resurrected to some level of heaven) and having "eternal life" (exaltation, godhood). A good example of the Mormon concept of the atonement is found in a parable by Apostle Boyd Packer in Gospel Principles, pp. 75-77, 1997 ed. According to his parable, Christ's atonement was like someone refinancing your huge debt. Your friend pays off the loan for you but you then must make payments to him. From this parable we see that Mormons do not see the atonement as a total payment for their sins, they must continue to make payments. Jesus has only refinanced the loan. Thus the atonement was necessary but did not fulfill all that was required for eternal life. Apostle Packer's story is helpful in contrasting the Mormon concept of the atonement with that of the Bible.

When discussing grace with them you could also ask about 2 Nephi 25:23, "by grace we are saved, after all we can do."

We need to explain that good works are a result of grace, not a way to achieve it (Gal. 5:22-23 and Eph. 2). One doesn't earn or pay for a gift. You will need to explain that grace is not a license to sin, that those who truly love God will want to please Him.

Temples and High Priests?

There are over a hundred LDS temples around the world in which they perform their baptisms for the dead, endowments and eternal marriage ceremonies for both the living and dead. A question to ask your Mormon friend is:

Eternal Life

Mormonism teaches that in order to gain eternal life (as opposed to merely entering heaven) one must be "worthy." It is achieved after a life of full activity in Mormonism, full tithing, temple marriage, etc. So a question to ask your friend is:

Point out that the Christian has the assurance of eternal life through faith in Christ, not church activity (see 1 John 5:13).

Nature of God

Mormonism teaches a totally different concept of God. However, rather than trying to explain the trinity to them, I focus on the basic nature of God the Father. Joseph Smith taught that God was once a mortal on some other world, which was ruled by yet another deity. (See Smith's sermon on the nature of God in History of the Church, vol. 6, pp. 302-317 [King Follet Sermon], or Teachings of the Prophet Joseph Smith, pp. 312, 342-354*, 370-373) Each god rose from mortality to immortality and earned the position of a god. He does not surpass the previous god, but is forever under his direction. It is sort of like an eternal pyramid system, or escalator, with each god answering to the one above him. If the Mormon denies this teaching ask him if he has read Smith's sermons on God. If Smith's doctrine of God is wrong he falls under the condemnation of Deuteronomy 13, a false prophet leading the people after a false god. (See our sheet LDS View of God Contradicts the Bible.) How do they reconcile Smith's doctrine of multiple gods with Isaiah 43:10-11 and Isaiah 44:8?

*These pages are a reprint of the King Follet Sermon, which can be found in History of the Church, vol. 6, pp. 302-317.

A Testimony?

The Mormon will often say that he knows the LDS Church is true from prayer and inner conviction. We need to point out that people all over the world have come up with different beliefs about God. Obviously sincerity and prayer are not enough to guard against false claims. That is why God has given us the Bible, so that we will have a standard measurement for truth claims. You might ask them:

We don't need to pray to know if we should rob a bank, or commit adultery, since God has already spoken on the issue. Thus we see that if someone claims a revelation contrary to what God has already spoken, we can know that it is a false teaching. Thus if Joseph Smith taught anything different from the Bible, like plural gods, he should be rejected. (Gal. 1:8-9 and Deut. 13)

While Christians value prayer and seek direction from God, this is not the Biblical method of testing a prophet. Every leader and doctrine must be examined in light of the Bible.


Remember that your life is already a witness to your LDS friends, one way or another. If they say you would make a good Mormon, take comfort. Your lifestyle is seen to be consistent with your claim to be a Christian, they just want to give you the rest of the gospel.

Challenge them to study the Bible (Acts 17:11-12). If Mormonism is a restoration of Christ's church, it will agree with what God has already revealed. Challenge them to think for themselves. Truth will stand up to investigation.

A Mormon quickly senses if you are talking from genuine concern and conviction, or if you just want an argument. Check your motives and attitude (see 2 Tim. 2:23-26 and Titus 3:2-9). As ambassadors for Christ we are to share His love and redemption.

"Always be full of joy in the Lord; ... Let everyone see that you are unselfish and considerate in all you do." (Philippians 4:4-5, Living Bible)
