It is recorded in all the Books of the Gospel that He Who is the Spirit spoke in words of pure light unto His disciples, saying: “Know that heaven and earth may pass away, but my words shall never pass away.” As is clear and evident to thine eminence, these words outwardly mean that the Books of the Gospel will remain in the hands of people till the end of the world, that their laws shall not be abrogated, that their testimony shall not be abolished, and that all that hath been enjoined, prescribed, or ordained therein shall endure forever.
