Spirit is God, and God is Mind, Truth. Inevitably, Truth must express itself intelligently. Truth, understanding itself, interprets itself without any need of a human medium. Truth's self-expression includes its self-interpretation, wherein is the language of Spirit. Spirit's language does not consist of human words; it is the Word of God which, according to the Gospel of John, was in the beginning, that is, in the forever Principle of the universe.
This language becomes ours as we align our thought with the scientific interpretation of the universe laid down by Mary Baker Eddy in "Science and Health with Key to the Scriptures," where she says (p. 272), "The divine Principle of the universe must interpret the universe." On page 117 of this textbook of Christian Science one is reminded that "God's essential language is spoken of in the last chapter of Mark's Gospel as the new tongue, the spiritual meaning of which is attained through 'signs following.'" After Christ Jesus' disciples had witnessed and understood, to a certain extent at least, his ascension, they perceived that the mighty works the Master had performed could and should be done also by them, because the Christ-power is confined to no person, is eternal, ever present, ever available, invariable, lawful. The commands to do the works and to "speak with new tongues" came simultaneously. In the understanding of the scientific interpretation of the universe, the universal Christ-power becomes available to redeem, heal, and save, wherein is found the meaning of the new tongue. Unless the new tongue is accompanied by "signs following," it is not the language of Spirit.
Christian Science is to this age the new tongue of Truth, the language of Spirit. Because the Science of Christianity evaluates everything from the standpoint of God, divine Principle, it presents the new, or real, value of the universe—real in the sense of God, divine Principle, being the source of all truth and thereby of reality. The reader will be illumined and greatly benefited by pondering Mrs. Eddy's autobiography, "Retrospection and Introspection," page 25, lines 10 to 19. Here he will find elaborated this revaluation in terms of the spiritual and eternal, in contradistinction to the material and temporal.
