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.

530. As has been stated, the names used in this chapter mean Churches, or what amounts to the same, doctrinal systems, for it is by virtue of its doctrine that a Church exists and takes its name. Thus Noah means the Ancient Church, or the doctrine that remained from the Most Ancient Church. The situation with Churches or doctrines has been stated already, namely that they dwindle away until nothing remains any longer of the goods and truths of faith. And when that point has been reached, the Church is in the Word called vastated. Nevertheless a remnant is always preserved, that is, some people are preserved, no matter how few, with whom the good and truth of faith persist. And unless that good and truth of faith were preserved with those people there would be no conjunction of heaven with the human race.

[2] As regards the remnants that reside with the individual, the fewer they are the less possible it is for the rational concepts and the factual knowledge he possesses to receive light; for the light of good and truth flows in from the remnants, or rather from the Lord by way of the remnants. If there were no remnants residing with a person, he would not be a human being, but someone far inferior to any animal. The fewer the remnants, the less he is a human being, while the more they are, the more he is a human being. Remnants are like a star in the sky; the smaller it is the weaker the light coming from it, but the greater it is, the brighter the light coming from it. The few things that did remain from the Most Ancient Church resided with those who constituted the Church called Noah. Those things were not however the remains of perception but of integrity, and also of doctrine deriving from the things of the Most Ancient Churches that were matters of perception. At that point therefore a new Church was raised up by the Lord. Being entirely different in disposition from the Most Ancient Churches, it is to be referred to as the Ancient Church, ancient from the fact that it existed at the last stage before the Flood and in the first period of time after it. This Church will in the Lord's Divine mercy be dealt with later on.
