Couple of differences between credibility the BIBLE vs. BOM is there are over 5000 ancient copies of the Bible in many languages; Dead Sea Scrolls, Early Church Fathers writings - They DOVETAIL together - also with very, very few copy errors; really no changes in doctrine - The Church, however, the authentic custodian of the Bible grows in understanding and authentic interpretation of the Bible
vs. say so of one Joseph Smith, arrested and found guilty of “glass-looking” “money digger” complete with peepstone - starts his career in jail & ends it in jail on the wrong end of a gun, dying in a gun fight; over 3900 copy errors and doctrinal changes in his “inspired” Book of Mormon. Funny: NO ONE SAW the Plates; NO ONE SAW the Angel; NO ONE SAW GOD THE FATHER as NO ONE SEES GOD AND LIVES (expect Jacob). No-Brainer for the Jews to be sure.
BYU’S Dr. Hugh Nibley said Joseph Smith did not publish the first vision story until 1842 (why not? surely that would be huge news at the time if it were true): “Joseph Smith’s ‘official’ account of his first vision and the visits of the angel Moroni was written in 1838 and first published in the Times and Seasons in 1842”. (Improvement Era, July 1961, p. 490)
in 1832, Smith claimed to have a revelation which stated that a man could not see God without the Priesthood - see Section 84 of D & C verse 21-22: "And without the ordinances thereof, and the authority of the priesthood, the power of godliness is not manifest unto men in the flesh: "For without this no man can see the face of God, even the Father and live.
Jump to Doctrines of Salvation, Joseph Fielding Smith, vol. 1, p.4:
“The Father and the Son appeared to the Prophet Joseph Smith before the Church was organized and the priesthood restored to the earth.”
Big Problem here as “truth” collapses: 1832 “revelation” suggests first vision story made up years after it supposedly occurred; there was NO PRIESTHOOD at supposed time of “first vision” in 1820 but D & C says needed a PRIESTHOOD that was NON-EXISTANT in order to “SEE GOD”
Poor ol’ Joseph Smith just kept digging deeper & deeper holes.
