Book of Mormon/Anachronisms/Biblical/Holy Ghost
This page is based on an answer to a question submitted to the FAIR web site, or a frequently asked question.
Why is the Holy Ghost mentioned so many times in the Book of Mormon prior to the time of Christ (e.g., 1 Nephi 10:17) and yet in the Old Testament there is hardly any mention of the Holy Ghost, especially with regard to his mission of bearing witness of the truth?
It is interesting to note that the same question arises about Satan in the Old Testament. There is very little information about Satan outside of the first two chapters of Job. Students of the Bible have observed that Satan is much more prevalent and "real" in the New Testament. The typical answer Biblical students give for this is the evolving understanding of doctrine from the Old Testament to the New Testament. Some who are more skeptical say that the New Testament period was perhaps more influenced by spiritual beliefs in devils and spirits than the earlier period.
But for Latter-day Saints there is a different perspective. We know that the knowledge of both Satan and the Holy Ghost has been part of gospel teaching from the time of Adam down. The fact that both are poorly represented in the Old Testament reinforces our belief that many plain and precious things were not adequately handed down to us from ancient times (see 1 Nephi 13:26–40). This was one of the great necessities for the Restoration—to restore the "fulness" of the doctrines and principles of the gospel, because they were not adequately transmitted into our time. The Book of Mormon in its plainness and simplicity, and uncorrupted nature, shows us a clearer picture of what was understood and believed about both Satan and the Holy Ghost by inspired prophets.
Similar criticisms are leveled at the Book of Mormon and the Church, because the Book of Mormon reveals the name of Jesus Christ prior to his birth. Again, the answer is, inspired prophets knew a great deal, unfortunately it wasn't adequately transmitted to us before the recovery of the Book of Mormon.
