LDS scholars have been presenting research or observations over the past decade or so that collectively lend weight to the modern origin theory. To be clear, none of these scholars would likely endorse the modern origin theory themselves; rather, they would tend to interpret their individual observations in other ways (e.g., via an expansionist theory). Still, when viewed collectively, and especially in light of other historical and literary anlysis by non-LDS researchers on the Book of Mormon,1 the modern origin theory unifies and makes sense of these observations:

Left: LDS scholar observations converge on a modern origin even though none individually would likely endorse a modern origin. Links to research and key observations are given below, going from the top (Nick Frederick) and moving clockwise.

Right: A number of other scholars have made more complete cases for a modern origin. The modern origin theory unifies all these disparate observations.

LDS Scholar observations

  1. Nick Frederick, BYU Religion Professor — The Book of Mormon contains at least 650 phrases that can convincingly be shown to be from the New Testament (i.e., not accidental). Language and themes from the New Testament are deliberately used in the Book of Mormon.

    what we have here is a conscious attempt to bring the language of the Book of Revelation into the Book of Mormon.

    other times the sequence of those proximity phrases will follow the same sequence in both the New Testament and in the Book of Mormon, which, again, suggests to me that we have a conscious attempt to draw upon the language of the New Testament in the Book of Mormon.

    Significance: We do not expect ancient authors to be pulling extensively from New Testament phraseology and themes in such a manner since the NT had not even been written at the time ancient authors were first engraving the plates and the books being pulled from were not transmitted by Jesus in the New World, at least based on the record of what was transmitted.

  2. Richard Bushman, famous LDS Historian and advisor of the Joseph Smith Papers Project made two public observations about the early 1800s literature in the Book of Mormon:

    … there is phrasing everywhere–long phrases that if you google them you will find them in 19th century writings. The theology of the Book of Mormon is very much 19th century theology, and it reads like a 19th century understanding of the Hebrew Bible as an Old Testament.

    The Book of Mormon has a lot of nineteenth-century Protestant material in it, both in terms of theology and of wording. I am looking for an explanation of how and why it is there.

  3. Grant Hardy, a foremost LDS Scholar on the Book of Mormon — The Isaiah we see in the Book of Mormon is not what we would expect to see from someone who came from Jerusalem in 600BC.

    Latter-day Saints sometimes brush such criticism [that the Book of Mormon pulls from deutero-Isaiah] aside, asserting that such interpretations are simply the work of academics who do not believe in prophecy, but this is clearly an inadequate (and inaccurate) response to a significant body of detailed historical and literary analysis.

    Recent Isaiah scholarship has moved … in favor of seeing the book of Isaiah as the product of several centuries of intensive redaction and accretion. In other words, even Isaiah 2–14 would have looked very different in Nephi’s time than it did four hundred years later at the time of the Dead Sea Scrolls, when it was quite similar to what we have today.

    Significance: We do not expect KJV Isaiah (even in its slightly modified form) to be in the Book of Mormon as it is represented were it a representation of an ancient text.

  4. Lincoln Blummell, BYU Religion Professor — notes that the end of Mark, which is quoted in the Book of Mormon by Moroni, is of dubious origin.

    Mark 16:8 is currently the earliest attested ending for Mark’s gospel (appearing in Codex Sinaiticus [א] and Codex Vaticanus [B] [the earliest complete manuscripts of Mark]), its abruptness is problematic …

    … others [of the early Christian fathers] seem not to have known about them [Mark 16:9–20] or were unsure of their authenticity …

    Significance: Moroni states that Jesus spoke to the disciples in the New World using the exact verbiage from a section of Mark that is almost certainly a later addition to the book of Mark.

  5. Thomas Wayment, BYU Religion Professor — Joseph Smith was influenced by Adam Clarke’s famous commentary on the Bible in production of the JST.

    Our research has revealed that the number of direct parallels between Smith’s translation and Adam Clarke’s biblical commentary are simply too numerous and explicit to posit happenstance or coincidental overlap. The parallels between the two texts number into the hundreds, a number that is well beyond the limits of this paper to discuss. A few of them, however, demonstrate Smith’s open reliance upon Clarke and establish that he was inclined to lean on Clarke’s commentary for matters of history, textual questions, clarification of wording, and theological nuance.

    Significance: Joseph Smith was both willing and able to weave external works from his time into religious documents, and he relied on Clarke without drawing mention from any of his scribes.

  6. Royal Skousen, BYU linguistics and English Professor — the BoM grapples with nuances in late 1600s theology.

    there is considerable evidence that the issues and the cultural milieu of the text date more from the late 1600s than the early 1800s

    And from The Language of the Original Text of the Book of Mormon:

    there are numerous issues which show that the Book of Mormon is concerned with what the Protestants dealt with and argued over during the 1500s and 1600s

    And Skousen now concedes that the process “involve[d] considerable intervention by the translator” (emphasis added):

    Is the Book of Mormon English translation a literal translation of what was on the plates? It appears once more that the answer is no. The blending in of specific King James phraseology, from the New Testament as well as the Old Testament, tells us otherwise. The Book of Mormon is a creative translation that involves considerable intervention by the translator (or shall we say translators, since we’re in a speculative mood). There is also evidence that the Book of Mormon is a cultural translation. Consider, for instance, the interesting case of the anachronistic use in the Book of Mormon of the noun bar, which consistently refers to the bar of judgment that we will stand in front of (and hold on to) on the day of judgment. The judgment bar is not a biblical or ancient term, but instead dates from medieval times.

    Significance: We do not expect ancient authors to have the context by which to weigh in on these debates with any sophistication. [However, there are numerous reasons we might expect reference to older theological debates from someone writing in the 1800s about religious matters, though.]

Conclusion

Most of the above scholars seem unaware of the vast body of evidence suggesting a modern origin and are likely to explain their observations using other models (for example, an expansionist model or to expect anachronisms); still, many of their honest observations lend significant credence to the possibility that the Book of Mormon was not produced by ancient minds.

Regardless, anyone who parses the early 1800s literature will observe that many, if not all, theological doctrines and themes advanced in the Book of Mormon had close precursors, variants, or a deep foundation in, the theology and thought of the early 1800s.
