1297. 'And let us burn them thoroughly' means the evils that stem from self-love. This is clear from the meaning of 'to burn, a burning, fire, sulphur, and bitumen' in the Word, where they have reference to evil desires, chiefly to those that belong to self-love, as in Isaiah,

Our holy house, and our splendour, where our fathers praised You, has been made into a blaze of fire, and all our pleasant places have been made into a waste. Isaiah 64:11.

In the same prophet,

Conceive chaff, bring forth stubble. Your wind is a fire that will consume you. Thus the peoples will be burnings of lime; [like] thorns cut down they will be burned in the fire. Isaiah 33:11-12.

And there are many other examples besides these. 'Burning' and 'fire' have reference to evil desires because they possess similar characteristics.

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.
