“In the day of regeneration, when all things are made new, … there will be the Jerusalem of old which shall be rebuilt according to the prophecy of Ezekiel. One will be the city of Zion, or of Enoch, which was taken from the earth when Enoch was translated and which will be restored; and the city Zion, or New Jerusalem, which is to be built by the seed of Joseph on this the American continent… . After the close of the millennial reign we are informed that Satan, who was bound during the millennium, shall be loosed and go forth to deceive the nations. Then will come the end. The earth will die and be purified and receive its resurrection. During this cleansing period the City Zion, or New Jerusalem, will be taken from the earth; and when the earth is prepared for the celestial glory, the city will come down according to the prediction in the Book of Revelation.” (Joseph Fielding Smith, Answers to Gospel Questions, 2:105-106)
