A ‘tell-tale’ sign the Book of Mormon is a 19th-century concoction, is the fact that of the many important things the Nephites could be praying to God about, they were focused on the importance of what the ‘name’ of the religion should be:
“And they said unto him: Lord, we will that thou wouldst tell us the name whereby we shall call this church; for there are disputations among the people concerning this matter.”
~3 Nephi 27:3~
Jesus rebukes them, yet continues to appease their question with an answer that seems to a) satisfy them, b) give Joseph Smith leverage in naming it, and c) addresses 19th-century bickering over the importance of naming a church.
His answer also gives license to the arrogant side of the Book of Mormon Jesus. Only once in the New Testament does Christ refer to “my church” (Matthew 16:18). Additionally, there is not a single instance in the New Testament where Jesus says “baptized in my name.” Yet, to give a new dynamic to him, Joseph Smith feels the need to add a self-centered angle to Jesus found nowhere in the Bible, to re-present him with more power and authority than was ever recorded in the Gospels. In fact, Jesus uses the words “me” eleven times, “I” twenty-four times, and “my” twenty-eight times in 3 Nephi 27.
That’s 63 instances in the 31 verses he speaks in.
If this is higher than normal when compared to any other 31 verses in any given chapter in the New Testament is unknown, but it seems uncharacteristic of the Biblical Jesus.
