A New Church
It was foretold in the Apocalypse (XXI, XXII) that at the end of the former Church a New Church was to be instituted, in which this would be the chief teaching: that God is One in Person as well as in Essence, in Whom is the Trinity, and that that God is the Lord. This Church is what is there meant by the New Jerusalem, into which only he can enter who acknowledges the Lord alone as God of Heaven and earth.
—Divine Providence, n. 263
The descent of the New Jerusalem cannot take place in a moment, but becomes a fact as the falsities of the former Church are removed. For what is new cannot enter where falsities have previously been engendered, unless these are eradicated; which will take place with the clergy, and so with the laity.
