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.

874. This describes the first state following temptation in the regeneration of the member of this Church, a state common to all who are being regenerated. It is a state when people imagine that they themselves are the source of the good they do and of the truth they think. And because they are still in the greatest obscurity, the Lord lets them cling to that opinion. But as long as they cling to that opinion which is false, no good deed they do nor any truth they think is the good or truth of faith. For whatever a person carries out from himself cannot be good since it has come from self, an impure and most unclean origin. From that impure and most unclean origin no good can possibly emerge, for the individual is thinking all the time about his own merit and righteousness. Some go even further, and look down on everybody else, as the Lord teaches in Luke 18:9-14. And others' attitudes are different again. People's selfish desires intermingle in such a way that the outside may look good while the inside is filthy. The good therefore that a person does in this state is not the good of faith. And the same applies to the truth he thinks. What he thinks may be the perfect truth; but as long as the proprium is the source of it, though it is in itself the truth of faith, he does not have the good of faith within him. To be the truth of faith all truth must include from the Lord the good of faith. Only then do they become good and truth.
