[Conclusion]
God has been gracious—never has more material been available that supports and illuminates the Book of Mormon. But we ought never to expect that such support will come in the forms or ways we wish.

Others may disagree without being unfaithful or fools. And they will never require us to misrepresent the learning of the world. The Book of Mormon, the Latter-day Saints, and the Church of Jesus Christ deserve far better than Meldrum’s pseudoscientific snake oil and strained proof-texting
