“There Cannot Be Any More Bible”
Every missionary who has labored among Christian nations has heard Nephi's prophecy- this basis for rejecting the Book of Mormon- fulfilled near countless times. The argument is, as the Lord suggests, most foolish. It is our modern counterpart to those of Jesus' day who rejected him in the pretense of being loyal to the Law of Moses, the irony being that loyalty to the Law of Moses demanded acceptance of Jesus as the Christ.
The purpose of the Law of Moses was to teach and testify of Christ. Such is also the purpose of the Book of Mormon, it being the most Christ-centered book ever written. Yet it is rejected in the name of loyalty to the Bible. The logical extension of such reasoning would be to reject the Gospel of Mark in the name of loyalty to Matthew or to reject the witness of Peter in the pretense of loyalty to Paul and his teachings. Indeed, some have done so, claiming contradictions between these early Apostles; yet the spirit, purpose, and doctrine of these special witnesses, like that of the Bible and the Book of Mormon, are the same.
