The entry into New Jerusalem, celebrated annually on December 12, symbolizes the union of the earthly and the heavenly, as well as the past and the future, which became the Day of the Lord, having no end. On December 12, 2018, Andrej Poleev became the first citizen of the New Jerusalem, named the Community Rus’. This event, predicted in the Revelation of John, happened on the Third Day, that is, at the beginning of the Third Millennium from the first appearance of Jesus Christ, and resembling His entry into Jerusalem on Palm Sunday in the year 33. The Kingdom of Heaven, which was then not of this world, now and forever becomes earthly and true in the City of God:

It had a great, high wall with twelve gates, and with twelve angels at the gates. On the gates were written the names of the twelve tribes of Israel. There were three gates on the east, three on the north, three on the south and three on the west. The wall of the city had twelve foundations, and on them were the names of the twelve apostles of the Lamb. ... The city does not need the sun or the moon to shine on it, for the glory of God gives it light, and the Lamb is its lamp. The nations will walk by its light, and the kings of the earth will bring their splendor into it. Its gates will never be shut at the end of the day, because there will be no night there. The glory and honor of the nations will be brought into it. Nothing impure will ever enter it, nor will anyone who does what is shameful or deceitful, but only those whose names are written in the Lamb's book of life. - Revelation 21
