754. There are various factors that cause the demise of a church. A primary factor is things that make what is false appear to be true. When what is false is taken to be true, then goodness that is truly and intrinsically good - which is called spiritual goodness - no longer exists. In that state, what we believe to be good is merely the earthly goodness that results from a moral life. The factors that cause the loss of truth, and therefore of goodness as well, are the two earthly kinds of love that are completely opposite to the two spiritual kinds of love. These two earthly kinds of love are known as love for ourselves and love of the world. When love for ourselves is dominant, it becomes the opposite of loving God. When love of the world is dominant, it becomes the opposite of loving our neighbor. Loving ourselves is wanting what is best for ourselves alone and not for anyone else unless we ourselves will benefit. Loving the world is similarly self-centered. When these types of love are deeply embedded in us they spread, like gangrene does through the body, and progressively destroy everything within us.

The biblical descriptions of Babylon make it very clear that a love like this has invaded the churches (Genesis 11:1-9; Isaiah 13; 14; 47; Jeremiah 50; Daniel 2:31-47; 3:1-7; ; ; ; and Revelation 17 and 18 from beginning to end). Babylon eventually developed such an exalted idea of itself that it not only transferred all the Lord's divine power to itself but also put tremendous effort into steering all the wealth in the world toward itself.

[2] There is also fairly substantial evidence that many of the leaders of the churches that separated from Babylon would themselves have developed loves that were similar if their power had not been restrained and curtailed. Where else does this path lead but to viewing oneself as God and the world as heaven? And yet taking this view corrupts every true teaching of the church. People who are exclusively earthly are incapable of recognizing or acknowledging truth that is actually and genuinely true; such people are incapable of being given such truth by God, because it rapidly turns into its opposite inside them and becomes false.

Besides these two kinds of love there are many other factors that bring truth and goodness to an end and cause the demise of the church, but they are only secondary and subordinate to the loves just mentioned.

902. 21:14 And the wall of the city had twelve foundations. This symbolically means that the Word in its literal sense contains all of the doctrines of the New Church.

The wall of the city symbolizes the Word in its literal sense (no. 898), and its twelve foundations symbolize all of the doctrines of the church - its foundations symbolizing doctrines, and the number twelve all. The church, moreover, is founded on doctrine, for it teaches how a person is to believe and live, and its doctrine is to be drawn only from the Word. That it is to be drawn from the Word's literal sense may be seen in The Doctrine of the New Jerusalem Regarding the Sacred Scripture, nos. 50-61.

Since the twelve foundations of the wall of the city New Jerusalem symbolize all of the church's doctrine, and the church is a church by virtue of its doctrine, therefore its foundations are described in more detail in verses 19 and 20 below.

The foundations of the earth are mentioned a number of times in the Word, and they do not mean the foundations of the earth, but the foundations of the church, inasmuch as the earth symbolizes the church (no. 285). And the foundations of the church are only ones that come from the Word and are called doctrines. For it is the Word itself that provides a foundation for the church.

[2] Doctrines drawn from the Word are symbolized by foundations also in the following passages:

Have you not understood the foundations of the earth? (Isaiah 40:21)

I will put My words in your mouth... to plant the heavens and found the earth... (Isaiah 51:16)

They do not acknowledge, they do not understand, they walk in darkness, all the foundations of the earth shake. (Psalms 82:5)

...the Word of Jehovah... who stretches out the heavens, lays the foundations of the earth, and forms the spirit of man within him. (Zechariah 12:1)

Jehovah... kindled a fire in Zion, which has devoured its foundations. (Lamentations 4:11)

The impious... shoot in darkness the upright in heart, because the foundations are being destroyed... (Psalms 11:2-3)

Hear, O mountains, Jehovah's quarrel, you strong foundations of the earth; for Jehovah has a quarrel with His people... (Micah 6:2)

...the floodgates on high are open, and the foundations of the earth are shaken. The earth is violently broken, the earth is split open, the earth is shaken... (Isaiah 24:18-20)

And so on elsewhere, as in Isaiah 14:32; 48:13; 51:13; Psalms 24:2; 102:25; 104:5-6; 2 Samuel 22:8, 16.

Whoever does not think that the earth symbolizes the church cannot help but think only naturally, even materially, when he reads in these places about the foundations of the earth. So it would be also if he were not to think of the city Jerusalem here as symbolizing the church when he reads about its wall, gates, foundations, streets, dimensions, and more, which are described in this chapter as features of a city, when in fact they are features of the church and so must be interpreted not materially, but spiritually.
