The concept of a "church" in the Writings is both complex and beautifully organic, linked with teachings on the nature of the Lord and the resulting nature of mankind.

The Writings say that the Lord, in His essence - His actual substance - is perfect, infinite love, a love that powered creation, that is the ultimate source of reality, and that sustains reality constantly. That love is expressed in form as perfect, infinite wisdom, which gave form to creation and gives form to reality.

Deep stuff! You can read more about that elsewhere, but what matters here is that all of creation, from the smallest elements to the whole of the universe, reflects that same structure. It's present in nature itself, powered by the heat (love) and light (wisdom) of the sun. It's present in the essential forms of life, with plants (which are rooted; which change little; which are unfeeling; which are powered by light) representing elements of wisdom and animals (warm, feeling, mobile, ever-changing, powered by heat) representing forms of love. It's present in the near-universal division into male (wisdom) and female (love) aspects of plants and animals alike.

That structure is also in each of us. In common language we might call these our hearts and our minds - what we want and what we think. The Writings commonly talk of them as good (love; what we want in our hearts) and truth (wisdom; what we know in our minds) or as will (heart) and understanding (mind). Not only do these elements define us, they are also key to our spiritual fates. We can use them to accept the Lord's love, come into the good of life and ultimately go to heaven. We can also use them to reject the Lord's love and trot off to hell.

And there are further layers. The Writings say that all human societies are in human form, with functions analogous to the human body. This is true from small groups like families to large companies to entire nations and ultimately to both the entire human race in this world and the entirety of heaven in the next.

Among the most important human societies are, naturally, churches. Since the concept of a "church" is based on the human form, though, churches as referred to in the Writings can take many forms. At one end of the scale, any one person who has true ideas of right and wrong and lives by them is a church himself or herself. At the other end of the scale, all those in the whole world who believe in love of the neighbor – and act from that belief – collectively make up one church.

Many other varieties lie between those two extremes, but most references to "church" in the Writings mean the community of those who have the Word, know the Lord, and follow His commandments. These people have access to the best possible truth and deepest possible understanding about the nature of the Lord and what He wants from us.

Such a church plays a vital role: The Lord works through it to get ideas about being good into people's minds and the desire to be good into the inner recesses of their hearts, reaching far beyond that church itself to touch everyone in the world. In fact, the Writings say there is in essence a marriage between the Lord and the church, with the church in the role of the bride and wife, producing true ideas and good desires the way a wife produces children.

To protect this function, the Lord has made sure that throughout history (and a good bit of prehistory) there has always been a church filling this role.

The first of these was the Most Ancient Church, represented by Adam; it was inspired by love of the Lord. The second was the Ancient Church, represented by Noah; it was inspired by love of the neighbor and knowledge of the Lord. The third was the Israelitish Church, which had no interior love of good but preserved ideas of the Lord. The fourth was the primitive Christian church, which had a new, more direct understanding based on the Lord's teachings. The fifth, according to the Writings, is to be based on the deeper understanding offered through the Writings and their explanations of the Bible.

There is much more that could be said, but we'll just emphasize one other point:

We as individuals are who we are based on what we love, not what we know. We will go to heaven or to hell based on what we love, not what we know. Knowing, thinking and seeking truth are important things, but their purpose is to shape, guide and serve our loves; love is ultimately what matters. The Writings make it abundantly and repeatedly clear that it is the same with churches: They are ultimately based on love, not knowledge, on their determination to serve the neighbor, not their external forms of worship. And if churches share that common purpose of serving the neighbor then they are in essence one, with doctrinal variations being of little consequence.

3963. 'Afterwards she bore a daughter' means the affection for all these, and also means the Church of faith in which good is present. This is clear from the meaning of 'a daughter' as an affection, and also as a Church, dealt with in 2363. But as to what the object of the affection is, or what kind of Church is meant, this is evident from whatever is added on to the word 'daughter'. For example, it is evident from the addition of 'Zion' after 'daughter' that the celestial Church, which is called 'the daughter of Zion', is meant; from the addition of 'Jerusalem' that the spiritual Church, which is referred to as 'the daughter of Jerusalem', is meant, and so on. In the present verse, in which nothing is added on to it, 'daughter' means the Church of faith in which good is present. For up to this point the subject has been the general truths which constitute faith in which good is present, and the reception and acknowledgement of those truths, that is to say, the truths that were meant, as has been shown, by the ten sons of Jacob dealt with above. And since immediately after these sons reference is made to the birth of a daughter it is evident from the train of thought that a Church is meant in which all these truths are present.

[2] Whether you call it the Church of faith in which good is present, or you call it the spiritual Church, it amounts to the same; or again if you call it the affection for all these, that is, all these general truths. For it is from the affection for truth in which good is present, and the affection for good from which truth springs, that the Church has its being, not from the affection for truth in which good is not present or the affection for good from which truth does not spring. People who are governed by an affection for truth but not by the good from which truth springs, that is, who do not live according to truths, are much mistaken when they say that they belong to the Church. Though within a congregation, they are outside the Church, for they are governed by the affection for evil to which truth cannot be joined. Their affection for truth does not originate in the Lord but in themselves, for they have themselves in view, their intention being by means of the truth they know to earn repute, and thereby important positions and wealth. But they do not have the Church in view, or the Lord's kingdom, let alone the Lord. But people governed by the affection for good from which truth does not spring do not belong to the Church even though they are within a congregation, for they are governed by natural good, not by spiritual, and allow themselves to be led into every kind of evil and also of falsity, provided that evil is made to look like good and falsity to look like truth, see 3470, 3471, 3518.

2363. 'Let me now bring them out to you' means blessedness from these, that is to say, from the affections for good and for truth. This is clear from the meaning of these words when they have reference to the affections meant here by 'daughters'. As regards what is actually involved in all this - that is to say, in the reality that blessedness and happiness lie solely within the affection for good and for truth - all are completely ignorant who are immersed in and take delight in evil. The blessedness lying within the affection for good and for truth is seen by them either as something that does not exist, or as something dreary. By some it is seen to be something painful, or even deadly. This is so with the genii and spirits in hell. They imagine and believe that if the joy belonging to self-love and love of the world were withdrawn from them, and consequently the joy belonging to evils resulting from those loves, no life would be left to them. But when they are shown that such a withdrawal is the starting-point to life itself, bringing blessedness and happiness within, they experience a certain sadness at the loss of their own joy. And when they are brought into the company of others whose lives are such, pain and torment take hold of them. In addition they also start to feel at the same time within themselves something death-like and dreadfully hellish. For this reason they refer to heaven, where that blessedness and happiness reside, as their hell, and insofar as they are able to remove and hide themselves from the Lord's face they go as far away as they can.

[2] Nevertheless everything that is blessed and happy lies in the affection for the good which flows from love and charity, and in the affection for truth that constitutes faith, insofar as such truth leads on to that good. This becomes clear from the fact that heaven, that is, angelic life, lies in everything blessed and happy and also from the fact that its influence is felt from things that are inmost, since it flows in from the Lord by way of inmost things, see 540, 541, 545. At the same time wisdom and intelligence enter in and fill the inner recesses of the mind itself, kindling good with heavenly flame and truth with heavenly light. And this is accompanied by a perception of blessing and happiness which can only be called indescribable. People who have entered this state perceive how empty, how dreary, and how deplorable the life is of those who are subject to evils resulting from self-love and love of the world.

[3] So that anyone may recognize the nature of this life, that is to say, the life of self-love and love of the world, or what amounts to the same, the life that goes with arrogance, greed, envy, hatred, revenge, ruthlessness, and adultery, let him who has the ability to do so caricature for himself some of these evils. Or if he is able, let him paint a picture that accords with the ideas he can get of it from experience, knowledge, and reason. He will in that case see, insofar as his drawing or painting of it is accurate, how shocking those evils are and that they are devilish forms with nothing human in them. After death all who perceive joy in such evils become devilish forms such as these. And the greater their joy the more dreadful those forms are.

[4] But on the other hand if he caricatures love and charity for himself or also finds an expression of it for himself in some outward form, he will see, insofar as his drawing or portrayal is accurate, that it is an angelic form full of blessed and beautiful things, which has what is heavenly and Divine within it. Can anyone believe that those two forms are able to exist side by side, or that the devilish form can be thrown off and transformed into one of charity, and that this can be achieved by means of faith to which the life is contrary? For after death everyone's life, or what amounts to the same, his affection, remains. At that time the nature of affection determines the nature of all his thought, and consequently his faith, which manifests itself as it had existed in his heart.
