For example:
"... These last records ... shall make known to all kindreds, tongues, and people, that the Lamb of God is the Eternal Father and the Savior ... " (Book of Mormon, 1830 edition, page 32)
In the 1964 edition it reads as follows:
"... These last records ... shall make known to all kindreds, tongues, and people, that the Lamb of God is the Son of the Eternal Father, and the Savior ..." (Book of Mormon, 1964 edition, 1 Nephi 13:40)
Another important change was made in 1 Nephi 11:18; this is page 25 of the 1830 edition. In the 1830 edition it read: "... Behold, the virgin which thou seest, is the mother of God, after the manner of the flesh." In modern editions it has been changed to read, "... Behold, the virgin whom thou seest is the mother of the Son of God, after the manner of the flesh." The words, the Son of, were inserted in the middle of the sentence. Verse 21 of the same chapter originally read: "And the angel said unto me, behold the Lamb of God, yea, even the Eternal Father!" It was changed to read: "And the angel said unto me: Behold the Lamb of God, yea, even the Son of the Eternal Father!" Verse 32 of the same chapter, which is on page 26 of the original edition, was also changed. In the 1830 edition it reads: "... the Everlasting God, was judged of the world; and I saw and bear record." It was changed to read: "... the Son of the everlasting God, was judged of the world; and I saw and bear record."
Hmmm....
We have no choice but to believe:
a. God makes mistakes
or
b. God allowed Joseph to make the same type of mistakes that were the reason for needing the Book of Mormon in the first place - rather than relying on the mistake riddled Bible.
In fact some of the errors in the KJV were also made in the Book of Mormon, coincidence?
