Fullness Of The Gospel?

The Church of Jesus Christ of Latter Day Saints claims to be the only church on earth to contain the fullness of the gospel of Jesus Christ.  Other churches are said to have a portion of truth but to be lacking in it’s fullness.  In an Ensign article Boyd K. Packer explained the Church’s position on this issue by comparing the gospel preached by non-Mormons to using a single key on a piano while the LDS Church is said to have the ability to play a symphony. 

“The gospel might be likened to the keyboard of a piano—a full keyboard with a selection of keys on which one who is trained can play a variety without limits; a ballad to express love, a march to rally, a melody to soothe, and a hymn to inspire; an endless variety to suit every mood and satisfy every need.  How shortsighted it is, then, to choose a single key and endlessly tap out the monotony of a single note, or even two or three notes, when the full keyboard of limitless harmony can be played.  How disappointing when the fullness of the gospel, the whole keyboard, is here upon the earth, that many churches tap on a single key. The note they stress may be essential to a complete harmony of religious experience, but it is, nonetheless, not all there is. It isn’t the fullness.”  Boyd K. Packer, “The Only True and Living Church,” Ensign, Dec 1971, 40

There are many doctrines unique to the LDS Faith – modern temple worship, sealings, eternal families and potential for godhood to name just a few.  Being the only church to hold these beliefs and believing they are central to God’s plan for mankind, it is easy to see why Mormons lay claim to the gospel’s fullness.  For example, Christians believe marriage is for this life only and does not exist in heaven.  A believing Mormon may look at this as an incomplete belief as they believe one can be married “for time and all eternity” in the Temple.  Thus making the marriage covenant carry on into Heaven.

While I understand the Mormon position, I find there are many problems with their claim.  For starters it is contradicted by their own scriptures.  The introduction to The Book of Mormon says it “contains, as does The Bible, the fullness of the everlasting Gospel.”  By their own admission The Bible contains the fullness of the gospel yet neither it nor The Book of Mormon contain any of the unique doctrines of the Mormon Church.  Virtually every single unique Mormon doctrine was introduced by Joseph Smith years after he published The Book of Mormon.  This provokes some puzzling questions and problems for the LDS Church.  If The Bible and The Book of Mormon contain the fullness of the gospel why are none of the unique Mormon doctrines contained in them?  Are these doctrines not part of the gospel’s fullness?  If so why do we need them and what is it that all other churches are missing which leave them lacking in fullness? Lastly, if I can lay hold to the gospel’s fullness from The Bible alone why do I even need the Mormon Church and why do they preach one must accept their gospel either in this life or vicariously in the spirit world to enter the Celestial Kingdom/Heaven?

While I disagree with many LDS doctrines, we do agree upon one thing… The Bible contains the fullness of the good news (Gospel) of Jesus Christ.  The Bible tells us.. 

Jesus Christ is the one and only True God, our Savior.  He died for our sins, was resurrected on the third day and has ascended to His throne in Heaven.  He alone has provided reconciliation with God.  Once we accept Him as our Savior and enter into a relationship with Him we can approach the throne of grace with confidence realizing our salvation is assured.

We don’t need a man-made church to get to Heaven.  We have our way… Jesus Christ alone.  All praise be to Him.


  • The fullness of the good news or gospel lies in Jesus. He is the new & everlasting covenant. Not temple marriage. I agree whole heartedly with you, darrell. He is all we need.

    Praising Him!


  • When I look at Mormonism, there is no “burning in the bosom” that would make me consider it, but there is an awfully strong burning in my brain that tells me that it simply isn’t true. I’ll stick with Biblical Christianity and continue to reject Mormonism for the following reasons:
    –The Jesus of Mormonism is not the Jesus of the Bible
    –The God of Mormonism is not the God of the Bible
    –There is no 1st century evidence for Mormon practices such as temple worship
    –There was no great apostasy. The church has always needed reformation, but has never needed restoration
    –There is no evidence whatsoever that the events described in the Book of Mormon actually occurred. The Christian Scriptures (OT and NT) on the other hand, are firmly grounded in history
    –I like wine and beer (I just thought I’d throw that one in)

    So… I’ll give a hearty “Amen” to the fullness of the gospel being found in the Bible.

  • It doesn’t help to be able to play a masterpiece on the piano if you are playing the wrong song.

  • I wish to refine my wording a little bit: I’ll give a hearty “Amen” to the fullness of the gospel being found in Jesus Christ, as revealed in the Bible.

    Great Gospel. I feel this is the mormon’s biggest stumbling block. They can’t see that the prophet’s of the the old testament along with the laws, comandment’s (which were to make us better people) and prophesy’s were to point to the coming of Jesus. And the new testament points to the saving Grace that come’s through Jesus Christ alone. Now thats the FULLNESS of the Gospel.

    God Bless jm

    Remarkably well-stated…thanks!

    Every church on the earth today contains truths; some more than others, but none the less, they all are correct in something. However, without the perspectives provided by the Book of Mormon, many of the truths in the Bible are difficult to find. Just as the Old Testament and the New Testament contain different parts of a whole truth, the Book of Mormon (Another Testament) contains more truths. This doesn’t mean that the Bible doesn’t contain the fullness of the gospel, but without the Book of Mormon, the fullness can not be understood. They must be used together for the whole truth. Another issue is that the Bible is translated by scholars. This means there are flaws. There are limited understandings by the monks who translated it while the Book of Mormon was translated by direct revelation and assistance from God the Father. Therefore, it is completely accurate. If the Bible was completely accurate, then more of the truths revealed in the Book of Mormon would be visible there also. Another thing is that Joseph Smith did not suddenly make up the unique doctrines of the Church of Jesus Christ of Latter-Day Saints, the interpretations of the scriptures which prove those doctrines were revealed to him when the time is right. The LDS church believes nothing that can not be proven with scripture. Certainly people interpret scriptures differently, and this is how false doctrines come about, but the Holy Spirit will reveal the correct interpretations if we desire and ask of God for the answers we need.

    If the Book of Mormon is so needed to understand the Bible and if it restored and clarified truth that is missing or not understood from the Bible, why isn’t the bulk of Mormonism contained in the Book of Mormon? 99% of doctrines that are unique to Mormonism are NO-WHERE to be found in the BOM. In fact, the Book of Mormon, in and of itself, could be said to be a rather orthodox book. For example, it teaches there is ONE and ONE God alone who has always been God, it does not teach the heretical view that God was once a man, nor does it teach the heresy of Eternal Progression. While it is a book of fiction, it could easily be seen as a book of fiction whose teachings are very consistent with orthodox theology. Mormonism only goes astray with its extra-biblical and extra-Book of Mormon teachings.

    Help me to understand where you are coming from. Exactly what teachings do you believe the Book of Mormon clarifies or brings to the table that are absent from the Bible as interpreted in light of “the faith once for all delivered to the Saints?”

    good job standing up for the truth!!!

    I am not a Mormon, but I am a Book of Mormon believer. Apparently you don’t know what the Book of Mormon is about.
    1. The Jesus in the Book of Mormon is the same Jesus as crucified by the Jews in Jerusalem.
    2. Their is only one God. He is omnipotent.
    3. Their was an Apostacy as spoken of by Charles Wesley, Roger Williams and others. In the Dark Ages the churh went into the Apostacy. Then the Church went into a reformation period. During those days the preisthood authority was taken from the earth. Joseph Smith received the plates and later the preisthood authority was restored to the earth.
    We do not qaccept the Doctrin &Covenants or any temple ordinances. The temple will be built in the new Jerusalem. The Choice Seer will convince the Seed of Joseph of the truth of the words they will receive when He comes in the last days. He will come in great power and authority likened unto Moses.
    Therefore what I say is true ask of God of the truthfulness of my words and he will reveal it unto you.

    Jesus Christ is the fullness of the Gospel.

  • Mmcguire52

    True the fulness of the Gospel is through the acceptance of Jesus christ into your life, for he died for our sins tht we may have redemption for our sins and be saved. Through his word in the Gospels we shall find the fulness The Book Of Mormon has the fulness of mthe Gospel in it the Bible has many mplain and precious things removed from the books. That is the reason for the Book Of Mormon to make plain of that which was removed from the books. We are to repent and be baptized, and follow his commandments which he gave unto us to follow.

  • 1Nephi3:7

    The fullness of the gospel actually refers to receiving the Second Comforter. Jesus Christ, having fulfilled the law and the prophets made this promise in the New Testament. As One being no respector of persons, this is a heavenly gift meant for all. The prophets of the Old Testament understood this well (Abraham, Isaac, Jacob, Moses, Isaiah, etc) as did His apostles–as did His prophets descended from the tribe of Joseph, of which the Book of Mormon is a record.

    “The Book of Mormon contains the fulness of the gospel of Jesus Christ. That does not mean it contains every teaching, every doctrine ever revealed. Rather, it means that in the Book of Mormon we will find the fulness of those doctrines required for our salvation. And they are taught plainly and simply so that even children can learn the ways of salvation and exaltation.” – Ezra Taft Benson.

    This is what we mean. The fulness of the Gospel from our perspective does not entail all doctrines. Rather it explains what Christ did for us through His atonement, and all things He has said we must do regularly in mortality to receive salvation and eternal life through His grace and mercy.

    Nephi wrote, speaking of the Bible, “When it proceeded forth from the mouth of a Jew it contained the fulness of the gospel of the Lord, of whom the Twelve apostles bear record.” But men have taken away from the Bible “many parts which are plain and most precious; and also many covenants of the Lord have they taken away,” which resulted in a loss of the gospel (1 Ne. 13:24-29).

    Latter-day Saints believe that this apostasy and corruption of the scriptures necessitated a later restoration of the fulness of the gospel through prophets called of God. This restoration began with the first vision of 1820 to the Prophet Joseph Smith and continued with subsequent revelations, including modern scripture and priesthood authority, which remain today in The Church of Jesus Christ of Latter-day Saints.

    Kevin, “historical Christianity” must include an apostasy as prophesied in the New Testament, for it actually occurred. The reason you do not believe that Jesus and the God of Mormonism are not the same as historical Christianity is because your belief is a post-apostasy belief. Certainly you recognize that your beliefs and church practices have little in common with those of the church that Christ left in Peter’s hands, who he gave the power of the priesthood to bind on earth and in heaven.
    BTW, there is ample evidence that the Hopewell Indians are the Nephites of the Book of Mormon, and that the surrounding Native Americans are the remnant of the Lamanites that it speaks of. More than this, we have the spirit of the Holy Ghost that Christ promised he would send. If you need a witness other than the Holy Ghost, something must be amiss in your life. Have you asked God in sincere prayer about these things? I have, and I have received a sure witness of these things. I also have the evidences that accompany the followers of Christ in my life, including answers to daily prayer, healing, and more sacred experiences that I cannot speak of. I testify that God has revealed himself to me and has shown me that Joseph Smith was a true prophet, who like Stephen was martyred for his testimony of Christ. I exhort you to exercise faith to ask God of these things directly having faith in Christ that he will not lead you astray, but will give you a true answer from his Holy Spirit.

    JM, the problem with your statement is that is exactly what they teach. The saved by grace doctrine of modern Christianity leaves out the rest of the gospel preached by Peter, Paul and other disciples. Martin Luther sure must have wasted his time posting his 99 theses, if all he had to do was tell the Catholic Church that they had erred because they didn’t simply teach the doctrine of salvation by grace, huh? He rightly recognized that the Church had long ago apostatized from the truth. That’s where the correct teachings were lost and error crept in. Reformations of man could not retrieve it, but only the promised restoration of God would… and did, through his true prophet Joseph Smith.

  • guest

    Many plain and precious truths of the Bible were lost due to the apostasy. Joseph Smith was commanded to translate this and restore these. You are also correct in stating that the restoration of the Holy Ghost gave a correct perspective in understanding the truths written in the Bible. Private interpretations were, and are, the largest problems “historical Christianity” had in their understanding of scripture. The promised Comforter leads us to all truth, and is the primary witness of the restored gospel of Jesus Christ.
