194. "'And the name of the city of My God, the New Jerusalem.'" This symbolically means that they will have the doctrine of the New Church engraved on their hearts.

The New Jerusalem symbolizes the New Church, and when it is called a city, it symbolizes the New Church in respect to its doctrine. Therefore to "write on him the name of the city of My God, the New Jerusalem," means, symbolically, that they will have the doctrine of the New Church engraved on their hearts.

To be shown that Jerusalem symbolizes the church, and that as a city it means the church in respect to its doctrine, see nos. 880, 881, below.

A city symbolizes doctrine because a land, and particularly the land of Canaan, symbolizes a church in its entirety; and the inheritances into which the land of Canaan was divided consequently symbolized various components of the church, and the cities in it doctrines. Because of this, when cities are mentioned in the Word, the angels understand them to mean nothing else. I have also had this attested for me through a good deal of experience.

The case with this is the same as with the symbolic meanings of mountains, hills, valleys, springs, and rivers, all of which symbolize such things as have to do with the church.

[2] That cities symbolize doctrines can be seen to some extent from the following passages:

The land shall be... emptied..., the land shall be turned upside down..., the land shall be profaned... The empty city shall be broken down... What is left in the city shall be waste, and the gate shall be stricken even to its destruction. (Isaiah 3; 4; 5; 10; 11; 12)

The lion has come up from his thicket..., to make your land a wasteland. Your cities will be destroyed... I beheld... Carmel a wilderness, and all its cities desolate... ...the land shall mourn... The whole city shall flee..., forsaken... (Jeremiah 4:7, 26-29)

The land there is the church, and the city is its doctrine. The devastation of the church by doctrinal falsities is described in this way.

The despoiler shall come upon every city, so that no city escapes. The valley also shall perish, and the plain shall be destroyed... (Jeremiah 48:8)

Likewise:

Behold, I have made you this day as a fortified city... against the whole land... (Jeremiah 1:18)

This was addressed to the prophet because a prophet symbolizes the doctrine of the church (no. 8).

On that day they will sing... in the land of Judah: "We have a strong city; salvation will God appoint for walls and bulwarks." (Isaiah 26:1-2)

...the great city was divided into three parts, and the cities of the nations fell. (Revelation 16:18-19)

(The prophet saw) on a very high mountain... the structure of a city to the south... (And an angel measured the wall, the gates, their chambers, and the vestibule of the gate,) and the name of the city... shall be JEHOVAH IS THERE. (Ezekiel 40:1ff., 48:35)

There is a river whose streams have made glad the city of God? (Psalms 46:4-5)

I will embroil Egypt with Egypt, so that... city (fights) against city, and kingdom against kingdom. (Isaiah 19:2)

Every kingdom divided against itself is brought to desolation, and every city... divided against itself will not stand. (Matthew 12:25)

Cities in these passages mean, in the spiritual sense, doctrines, as is the case also in Isaiah 6:11; 14:4, 17, 21; 19:18-19; 25:1-3; 33:8-9; 54:3; 64:10, and elsewhere.

[3] From the symbolic meaning of a city it can be seen what cities mean in this parable of the Lord:

A... nobleman (going) into a far country to receive for himself a kingdom..., delivered to (his servants) minas (with which to) do business... ...when he returned..., he (called the) servants... The first came, saying, ."..your mina has earned ten minas," and he said to him, ."..good servant..., you shall have authority over ten cities." And the second came, saying, ."..your mina has earned five minas." And he said... to him, "You also be over five cities." (Luke 19:12-19)

Cities here likewise symbolize doctrines or doctrinal truths, and to be over them is to be intelligent and wise. Thus to give power over them is to impart intelligence and wisdom. Ten symbolizes much, and five some. It is apparent that to do business and earn a profit means to acquire intelligence for oneself by making use of one's abilities.

[4] That the holy city Jerusalem symbolizes the doctrine of the New Church is clearly apparent from its description in chapter 21 of the book of Revelation, for it is described in respect to its dimensions, its gates, and its wall and foundations, and inasmuch as Jerusalem symbolizes the church, these can symbolize nothing other than matters having to do with its doctrine. Neither is the church a church on any other basis.

Because the city Jerusalem means the church in respect to doctrine, it is therefore called the City of Truth (Zechariah 8:3-4), and in many places a holy city, and this because holiness is predicated of truths derived from the Lord (no. 173).

174. "'Who has the key of David, who opens and no one shuts, and shuts and no one opens.'" This symbolically means, who alone has the omnipotence to save.

David means the Lord in respect to Divine truth. The key symbolizes the Lord's omnipotence over heaven and hell. And to open so that no one shuts, and to shut so that no one opens, means, symbolically, to lead out of hell and introduce into heaven, thus to save, the same as in no. 62 above, where this was explained.

To be shown that David means the Lord in respect to Divine truth, see The Doctrine of the New Jerusalem Regarding the Lord, nos. 43, 44.

The symbolic meaning of the key here is the same as that of the keys of Peter (Matthew 16:15-19), ¹ as may be seen explained in no. 798 below. The same is also meant by this declaration to all the disciples,

Whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven. (Matthew 18:18)

For the twelve disciples represented all elements of the church as regards its goods and truths, while Peter represented the church in respect to its truth; and it is truths and goods, thus the Lord from whom they come, that save a person.

The key of David given to Eliakim has also the same meaning, concerning which we read,

I will give your government into his hands, that he may be as a father to the inhabitants of Jerusalem and to the house of Judah, and I will place on his shoulder the key of the house of David, so that he may open and no one shut, and close and no one open. (Isaiah 22:21-22)

The person referred to as he here was the person over the house of the king, and the house of the king symbolizes the church in respect to Divine truth.
