A reading from the book of Revelation.
The angel carried me away in spirit to the top of a very high mountain and showed me the holy city Jerusalem coming down out of heaven from God. It gleamed with the splendor of God. The city had the radiance of a precious jewel that sparkled like a diamond. Its wall, massive and high, had twelve gates at which twelve angels were stationed. Twelve names were written on the gates, the names of the twelve tribes of Israel. There were three gates facing east, three north, three south and three west. The wall of the city had twelve courses of stones as its foundation, on which were written the names of the twelve apostles of the Lamb. I saw no temple in the city. God Almighty and the Lamb were themselves the temple. The city had no need of sun or moon, for the Glory of God gave it light, and its lamp was the Lamb.
