In the Christian Science textbook, "Science and Health with Key to the Scriptures," by Mary Baker Eddy, beginning on page 502 the author states: "There is but one creator and one creation. This creation consists of the unfolding of spiritual ideas and their identities, which are embraced in the infinite Mind and forever reflected. These ideas range from the infinitesimal to infinity, and the highest ideas are the sons and daughters of God." To those students of Christian Science who have gleaned some knowledge of the new-old truth which Mrs. Eddy, through her writings, has given to this age and which, in proportion as it is apprehended and applied to human thinking, is freeing the world from the bondage of false material beliefs which combine to make up the sum total of human misery, it is obvious that when the author wrote the words above quoted she had caught a glimpse of that city described by the Revelator as "the holy city, new Jerusalem, coming down from God out of heaven," and again as "the city" which "lieth foursquare."
On page 592 of Science and Health Mrs. Eddy defines New Jerusalem as "Divine Science; the spiritual facts and harmony of the universe; the kingdom of heaven, or reign of harmony." In the chapter entitled "The Apocalypse," in the same book, she has clearly set forth so that all who will may learn, that this holy city, this New Jerusalem is no more nor less than that state of perfect spiritual consciousness, cleansed of all materiality, to which all the children of men must ultimately attain before they may be accounted worthy of the kingdom of heaven wherein nothing can enter "that defileth ... or maketh a lie."
Christ Jesus, the Way-shower, on the night before the crucifixion, in that wonderful prayer offered up in the Garden of Gethsemane where he had gone with his disciples after they had eaten the Passover, and he had departed from them for a short distance that he might be alone with God, has revealed the key whereby all may enter that kingdom, in these words, "And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent;" and in Jeremiah 31:34 the promise is found: "They shall allknow me, from the least of them unto the greatest of them, saith the Lord: for I will forgive their iniquity, and I will remember their sin no more."
