I think you have misunderstood the meaning of the word gospel.
I don't think so, Logo. (Unlike Mormons who tend not to check out historic definitions of biblical concepts, but simply take their leaders at face value, I double-checked Lds.org):
The gospel is our Heavenly Father's plan of happiness. The central doctrine of the gospel is the Atonement of Jesus Christ. The Prophet Joseph Smith said, "The first principles and ordinances of the Gospel are: first, Faith in the Lord Jesus Christ; second, Repentance; third, Baptism by immersion for the remission of sins; fourth, Laying on of hands for the gift of the Holy Ghost" (Articles of Faith 1:4).
Lds.org glossary definition of 'gospel'
Now. Let's again "overlay" some of those non-existent Book of Mormon teachings to see if it fits this definition:
Lds.org says the Mormon gospel focuses on a "plan of happiness" -- what Lds writings have frequently called the "eternal plan of salvation." Certainly the "happiest" aspects Mormon writings focus in on is families living eternally forever with God.
(a) #5 & #15 supposedly detail (among other ways) how you do that. Subtract #5 and/or #15 from a Mormon's life -- say a never-married Mormon...or a non-temple Mormon...and they won't directly participate in the "happiest" aspect of heaven -- living eternally with Heavenly Father in the celestial kingdom.
(b) And do you also mean to imply that #4 -- exaltation -- has nothing to do with the Mormon "gospel?" Are you now saying that exaltation has NOTHING to do with the Mormon eternal plan of salvation that leads to supposed "happiness?"
(c) Lds.org also says: The central doctrine of the gospel is the Atonement of Jesus Christ. Are you now telling us that the non-Book of Mormon teaching of "Where in the Book of Mormon does it teach the blood of Christ does not cleanse certain sins?" has NO relevance to Christ's atonement? Really?
So what is the gospel according to mormonism. Like all of their doctrines, nailing it to the wall is like that of jello. > Here is what joseph smith said as the first principle of the gospel - It is the first principle of the Gospel to know for a certainty the character of God and to know that we may converse with him as one man converses with another, and that he was once a man like us; yea, that God himself the Father of us all, dwelt on an earth the same as Jesus Christ himself did;. . . .
Here, then, is eternal life--to know the only wise and true God; and you have got to learn how to be Gods yourselves, and to be kings and priests to God, the same as all Gods have done before you,--namely, by going from one small degree to another, and from a small capacity to a great one,--from grace to grace, from exaltation to exaltation, until you attain to the resurrection of the dead, and are able to dwell in everlasting burnings and to sit in glory
The gospel of mormonism was also clarified by Brigham Young -
"Gospel of the Son of God that has been revealed is a plan or system of laws and ordinances, by strict obedience to which the people who inhabit this earth are assured that they may return again into the presence of the Father and the Son" (JD, 13:233)
So according to young, this gospel also is a system of rules, laws and ordinances requiring strick compliance.
Looks like Colofornian has it pretty well nailed.
Lds.org glossary partial definition of gospel (you know, the place Paragon Defender always tells us to go for to search for camels who are hidden in the needles of haystacks):
The central doctrine of the gospel is the Atonement of Jesus Christ.
From the article: NEVER does the Book of Mormon hint that there are sins beyond the cleansing power of Christ's blood.
Q. Doesn't the "atonement," the supposed "central doctrine of the" Mormon "gospel" have anything to do with how extensive or which sins are cleansed by his blood?
And when Brigham Young taught that certain sins would not be under "The blood of Christ" -- that His blood "will never wipe that out, your own blood must atone for it; and the judgments of the Almighty will come, sooner or later, and every man and woman will have to atone for breaking their covenants" ... (Discourses of Brigham Young, p.385). pray tell...why is that widely known as "blood atonement"???
...the Book of Mormon knowns of no limiting power as to which sins the atonement would cleanse....
...& Brigham taught there was such a limit, and that self-blood trumps Jesus' blood on some sins...
...But it's all related to various teachings of the atonement...
...An atonement which Lds.org says is the "central doctrine of the gospel"...
...And then you accuse me of misfiring on my definition of the Mormon "gospel"...
...Can you say...
...Lack of intellectual integrity OR horrific apologetics' application & faulty accusation on your part...?
And then we're also supposed to do the mental gymnastics you've done and conclude that Lds "apostle" Bruce McConkie's quote from the article is also somehow "irrelevant" to the Mormon doctrine of the "atonement?" (Yes? No?)
McConkie: "But under certain circumstances there are some serious sins for which the cleansing of Christ> does not operate, and the law of God is that men must have their own blood shed to ATONE for their sins" (Mormon Doctrine, pg. 92).
So you're SERIOUSLY telling us that McConkie's use of the word "atone" here has NOTHING to do with the Lds usage of "atonement," which in turn is the central doctrine of the Mormon gospel per Lds.org?
All so that you can keep intact Smith's repeated canonized claim that the Book of Mormon contains the "fulness" of the everlasting gospel?
Tell you what? Show some intellectual integrity. Have you considered your choices here...of either telling us...
...you concede the Book of Mormon has indeed failed to convey the "fulness" of the everlasting "gospel," Mormon-style, as it pertains to a full teaching on the atonement.
...Or...you can just label before all of us that Brigham Young and Bruce McConkie were false "prophets" on at least the teaching of the atonement.
Who lied in a false "prophet" way? Joseph Smith in the D&C? Or Brigham Young & Bruce McConkie in other venues?
(Your third choice...accusing me of misdialing the number for defining the Mormon "gospel" misfired and failed to hit the mark...unless you want to accuse Paragon Defender's fave link of flunking in its definition of the Mormon "gospel")
Tell us the MORMON meaning of the word.
