“It is clear at the outset that the sermon in the Book of Mormon is built upon one overwhelmingly important premise that is not so obvious in the New Testament—that the doctrines taught and the blessings promised are predicated upon first principles, on saving ordinances and covenants of the gospel, including the baptismal covenant, which brings people through ‘the gate’ to the strait and narrow path leading to eternal life. As Christ taught here, so Nephi taught earlier—that these first principles and ordinances constitute the ‘doctrine of Christ’” (Holland, Christ and the New Covenant, 261–62).
