63. The Holy City, New Jerusalem, means that new church in respect to its doctrine. That is why it was seen descending out of heaven from God, for a doctrine of genuine truth comes from no other source than the Lord through heaven.

Because the church in respect to its doctrine is meant by the Holy City, New Jerusalem, therefore it is said to be prepared as a bride, adorned for her husband (Revelation 21:2), and after that we are told:

One of the seven angels...came to me and spoke with me, saying, “Come, I will show you the bride, the Lamb’s wife.” And he carried me away in the spirit onto a...high mountain, and showed me the great city, the Holy Jerusalem, descending out of heaven from God. (Revelation 21:9-10)

People know that a bride and a wife mean the church when the Lord is meant by the bridegroom and husband. The church is a bride when it wishes to receive the Lord, but a wife when it does receive Him.

It is apparent that the Lord is meant by the husband there, for the bride is called the Lamb’s wife.

2943. 'To all entering into the gate of his city, saying' means matters of doctrine through which one comes to faith. This is clear from the meaning of 'a gate' as a place of entry and so as that which, in the same way as a door, leads in, dealt with in 2145, 2152, 2356, 2385, and from the meaning of 'a city' as truth, which constitutes faith, dealt with in 402, 2268, 2449, 2451, 2712. In the Ancient Church a city was not like the city of later or of modern times. That is to say, a city did not consist of a collection or gathering together of individuals but of separate families living side by side. A family descended from the same forefather constituted a city. The city of Nahor, for example, to which Abraham's servant went to betroth Rebekah to Isaac, Genesis 24:10, consisted of the family of Nahor which was there. And Shalem, the city of Shechem, to which Jacob came after his departure from Paddan Aram, Genesis 33:18 and the whole of Chapter 34, consisted of the family of Hamor and Shechem which was there. And the same was so with all other cities in those times.

[2] And as it had come down to them from the most ancient people that nations and families represented heavenly communities, and so the things of love and charity, 685, 1159, therefore when a city is mentioned instead of a family, and a people instead of a nation, truth that constitutes faith is meant. It is also why in the genuine sense the city of God and the holy city mean faith in the Lord. And as 'a city' meant faith, 'the gate of the city' means matters of doctrine through which one comes to faith. The same was also meant in the Jewish representative Church by the judges and elders sitting in the gate of the city and giving judgement there, as is evident from historical sections of the Word, and also in Zechariah,

These are the things that you shall do: Speak the truth, everyone to his companion; judge in your gates the truth and the judgement of peace. Zechariah 8:16.

And in Amos,

Hate evil, and love good, and establish judgement in the gate. Amos 5:15.

'A gate' also means the place of entry into the rational mind, and the rational mind is compared to a city, see 2851.
