mormonism says they use the KJV Bible, however the qualifier “as far as its translated correctly”, and Joseph Smith added/changed to it.
In addition if the BofM contradicts the Bible, the fall back is the BofM.
Joseph Smith’s translation of the KJV Bible
Matthew 6:25-27
25. And, again, I say unto you, go ye into the world, and care not for the world: for the world will hate you, and will persecute you, and will turn you out of their synagogues.
26. Nevertheless, ye shall go forth from house to house, teaching the people; and I will go before you.
27. And your heavenly Father will provide for you whatsoever things ye need for food, what ye shall eat; and for raiment, what ye shall wear or put on.”
King James Bible:
Matthew 6:25-27
25 Therefore I say unto you, Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment?
26 Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?
27 Which of you by taking thought can add one cubit unto his stature?
And, of course, hardly ANY of MORMONism's 'doctrines' come from either the BoM or the KJV bible; but from OTHER 'scriptures' that their god(s) have revealed to their 'prophets'.
(It must be a fearful thing, to be an SLC mormon!)
"Now if any of you will deny the plurality of wives, and continue to do so, I promise that you will be damned;
and I will go still further and say, take this revelation, or any other revelation that the Lord has given,
and deny it in your feelings, and I promise that you will be damned.
Brigham Young - JoD 3:266 (July 14, 1855)
