905. 21:16 The city is laid out as a square. This symbolizes justice in the New Church.

The city was seen as square because a square or quadrilateral form symbolizes justice, inasmuch as a triangle symbolizes rectitude, all of these being symbols on the lowest level, which is the natural one.

A square or quadrilateral layout symbolizes justice because it has four sides, and the four sides face the four cardinal points of the compass; and to face the four cardinal points equally is to regard everything equitably. That is why there were three gates on each side giving entrance into the city, and why it is said in Isaiah,

Open the gates, that a righteous nation which keeps its fealties may enter in. (Isaiah 26:2)

The city was laid out as a square in order that its length and breadth might be equal, the length symbolizing the goodness of the New Church, and the breadth its truth, and when goodness and truth are in balance, then there is justice.

It is because a square has this symbolic meaning that we say in everyday speech that this or that man deals squarely, meaning a man who does not incline unjustly to either one party or the other.

Because a square symbolizes justice, therefore the altar of burnt offering was square (Exodus 27:1), which symbolized a worship springing from a celestial goodness and consequent truth. The altar of incense, too, was square as well (Exodus 30:1-2). And other objects also were square.

895. 21:9 Then one of the seven angels who had the seven bowls filled with the seven last plagues came to me and talked with me, saying, "Come, I will show you the bride, the Lamb's wife." This symbolizes an influx and revelation from the Lord from the inmost of heaven regarding the New Church, which will be conjoined with the Lord through the Word.

One of the seven angels who had the seven bowls filled with the seven last plagues and who talked with John means the Lord flowing in from the inmost of heaven and speaking through the inmost of heaven, here revealing the things that follow. That this angel means the Lord is apparent from the exposition of chapter 15, verses 5-6, which says:

After these things I looked, and behold, the temple of the tabernacle... in heaven was opened. And out... came the seven angels having the seven plagues... (Revelation 15:5-6)

This symbolically means that the inmost of heaven appeared, where the Lord is present in His holiness and in the Law contained in the Ten Commandments, as may be seen in nos. 669, 670 above.

It is apparent also from the exposition of chapter 17:1, which says:

Then one of the seven angels who had the seven bowls came and spoke with me, saying..., "Come, I will show you the judgment of the great harlot...." (Revelation 17:1)

This symbolizes an influx and a revelation from the Lord from the inmost of heaven about the Roman Catholic religion, as may be seen in nos. 718, 719 above.

It is apparent from this that one of the seven angels who had the seven bowls filled with the seven last plagues coming to John and talking with him means the Lord flowing in from the inmost of heaven; that coming to him and showing him symbolizes a revelation; and that the bride, the Lamb's wife, symbolizes the New Church, which will be conjoined with the Lord through the Word, as in no. 881.

This church is called a bride when it is being established, and a wife after it has been established. Here it is called a bride and wife because it is of a surety going to be established.
