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.

3310. 'A man of the field' means the good of life that has its origin in matters of doctrine. This is clear from the meaning of 'the field'. In the Word reference is made in many places to the earth (or the land), the ground, and the field. When used in a good sense 'the earth' means the Lord's kingdom in heaven and on earth, and so the Church, which is the Lord's kingdom on earth. 'The ground' is used in a similar though more limited sense, 566, 662, 1066-1068, 1262, 1413, 1733, 1850, 2117, 2118 (end), 2928; and the same things are also meant by 'the field', though in a more limited sense still, 368, 2971. And since the Church is not the Church by virtue of matters of doctrine except insofar as these have the good of life as the end in view, or what amounts to the same, unless matters of doctrine are joined to the good of life, 'the field' therefore means primarily the good of life. But in order that such good may be that of the Church, matters of doctrine from the Word which have been implanted within that good must be present. In the absence of matters of doctrine the good of life does indeed exist, but it is not as yet that of the Church, and so not as yet truly spiritual, except in the sense that it has the potentiality to become so, like the good of life as this exists with gentiles who do not possess the Word and therefore do not know the Lord.

[2] That 'the field' is the good of life in which the things of faith, that is, spiritual truths existing with the Church, are implanted, becomes quite clear from the Lord's parable about the sower in Matthew,

A sower went out to sow, And as he sowed some fell on the pathway, and the birds came and devoured them. Some fell on rocky ground where they did not have much soil, ¹ and immediately they sprang up, since they had no depth of soil ² , but when the sun rose they were scorched; and since they had no root they withered away. Some fell among thorns, and the thorns came up and choked them. But some fell on good soil ² and yielded fruit, some a hundredfold, some sixty, some thirty. He who has an ear to hear let him hear. Matthew 13:4-9; Mark 4:3-9; Luke 8:5-8.

This describes four types of land or ground within the field, that is, within the Church. The fact that here 'the seed' is the Lord's Word, and so the truth which is called the truth of faith, and that 'the good soil' is the good which is called the good of charity is evident to anyone, for it is the good in man that receives the Word. 'The pathway' is falsity, 'rocky ground' is truth which is not rooted in good, 'thorns' are evils.

[3] With regard to the good of life which has its origin in matters of doctrine being meant by 'a man of the field', the position is that those who are being regenerated first of all do good as matters of doctrine direct them, for they do not of themselves know what good is. They learn to do good from matters of doctrine concerning love and charity; from these they know who the Lord is, who the neighbour is, what love is, and what charity is, and so what good is. Those who have come into this stage are stirred by the affection for truth and are called 'men (vir) of the field'. But after that, once they have been regenerated they do good not from matters of doctrine but from love and charity, for the good itself which they have learned about through matters of doctrine exists with them, and they are in that case called 'men (homo) of the field'. It is like someone who is by nature inclined to commit adultery, steal, and murder but who learns from the Ten Commandments that such practices belong to hell and so refrains from them. In this state he is influenced by the Commandments, for he fears hell and learns from those Commandments and similarly from much else in the Word how he ought to conduct his life. In his case when he does what is good he does it from the Commandments. But when good exists with him he starts to loathe adultery, theft, and murder to which he was previously inclined. In this state he no longer does what is good from the Commandments but from the good which by now resides with him. In the first state the truth he learns directs him to good, but in the second state good is the source of truth taught by him.

[4] The same also applies to spiritual truths which are called doctrinal and are more interior Commandments still. For matters of doctrine are interior truths which the natural man possesses, the first truths there being sensory ones, the second truths being factual, and interior truths matters of doctrine. The latter are based on factual truths inasmuch as a person can have and retain no idea, notion, or concept of them except from factual truths. But the foundations on which factual truths are based are sensory truths, for without sensory truths nobody is able to possess factual ones. Such truths, that is to say, factual and sensory, are meant by 'a man skilled in hunting', but matters of doctrine are meant by 'a man of the field'. Such is the order in which those kinds of truths stand in relation to one another in man. Until a person has become adult therefore, and through sensory and factual truths possesses matters of doctrine, he is incapable of being regenerated, for he cannot be confirmed in the truths contained in matters of doctrine except through ideas based on factual and sensory truths - for nothing is ever present in a person's thought, not even the deepest arcanum of faith there, which does not involve some natural or sensory idea, though generally a person is not aware of the essential nature of such ideas. But in the next life the nature of them is revealed before his understanding, if he so desires, and also a visual representation before his sight, if he wants it; for in the next life such things can be presented before one's eyes in a visual form. This seems unbelievable but it is nevertheless what happens there.

6432. 'The blessings of the breasts' means with affections for goodness and truth. This is clear from the meaning of 'the breasts' as affections for goodness and truth. 'The breasts' means those affections because the breasts communicate with the generative organs, and for that reason they too belong to the province of conjugial love (regarding that province see 5050-5062). Now conjugial love corresponds to the heavenly marriage, which is a marriage of goodness and truth (for conjugial love comes down from that marriage, see 2618, 2728, 2729, 2803, 3132, 4434, 4835, 6179), and therefore 'the breasts' means affections for goodness and truth. In addition they derive that meaning from the fact that the breasts are what feed infants and so mean, through the affection that goes with breast-feeding, conjugial love when joined to the love of offspring.

[2] The same affections are also meant by 'the breasts' in Isaiah,

You will suck the milk of nations, and the breasts of kings you will suck. Instead of bronze I will bring gold, and instead of iron silver. Isaiah 60:16-17.

'Sucking the breasts of kings' stands for good obtained from truth, for by 'kings' truths are meant, 1672, 2015, 2069, 3009, 3670, 4575, 4581, 4966, 5044, 5068, 6148. 'The milk of nations' and 'the breasts of kings' plainly mean some profoundly spiritual matter, for those words would otherwise be meaningless. The fact that goodness and truth are meant is clear from the words that follow, which are 'Instead of bronze I will bring gold, and instead of iron silver'; for 'bronze' is natural good, 425, 1551, and 'gold' celestial good, 113, 1551, 1552, 5658; 'iron' is natural truth, 425, 426, and 'silver' spiritual truth, 1551, 2954, 5658, 6112.

[3] In Ezekiel,

As regards increase, I gave you to be like the seed of the field, out of which you grew up and matured and reached full beauty; your breasts were formed and your hair had grown. Ezekiel 16:7.

This refers to Jerusalem, which here means the Ancient spiritual Church. 'Breasts that were formed' stands for interior affections for goodness and truth, 'your hair had grown for exterior affections belonging to the natural - 'hair' being the natural as regards truth, see 3301, 5247, 5569-5573. These words plainly contain a spiritual sense which is not visible in the letter, for without that sense why would it say of Jerusalem that its breasts were formed and its hair had grown?

[4] In the same prophet,

Two women, the daughters of one mother, committed whoredom in Egypt. In their youth they committed whoredom; there their breasts were squeezed, and there they contemplated their virgin busts. Ezekiel 23:2-3, 8, 21.

This passage in Ezekiel states that the two women are Jerusalem and Samaria, by whom Churches are meant in the internal sense. The statement that in their youth they committed whoredom with Egypt means that they falsified the truths of the Church by their use of factual knowledge - 'committing whoredom' is falsifying truths, see 2466, 4865, and 'Egypt' is factual knowledge, 1164, 1165, 1186, 1462, 5700, 5702. Consequently 'their breasts were squeezed' stands for affections for goodness and truth that became perverted through falsifications. The fact that the women's whoredom and the squeezing of their breasts mean such things can be seen by those who are prepared to look into what is meant in the description of those women.

[5] In Hosea,

Contend with your mother, let her remove her whoredoms from her sight, ¹ and her adulteries from between her breasts, lest perhaps I strip her naked, and make her like a wilderness, and set her like a dry land, and slay her with thirst. Hosea 2:1, 3.

'Mother' here stands for the Church, 289, 2691, 2717, 3703, 4257, 5581, whoredoms' for falsifications of truth, 2466, 4865, 'adulteries' for adulterations of good, 2466, 2729, 3399. Consequently 'adulteries from between her breasts' stands for adulterated affections for goodness and truth, 'stripping naked' for depriving of all truth, 1073, 4958, 5437, 'making like a wilderness, setting like a dry land, and slaying with thirst' for the annihilation of all truth.

[6] In the same prophet,

Give them a miscarrying womb and dry breasts. Hosea 9:14.

'Dry breasts' stands for affections for neither truth nor good. In Isaiah,

O women without anxiety, stand still, hear My voice; O confident daughters, perceive My speech with your ears. Strip and make yourself bare, and gird [sackcloth] around your waist ² - people beating themselves on their breasts for the fields of unmixed wine, and the fruitful vine. Isaiah 32:9, 11-12.

'Daughters' stands for affections, 2362, 3024, 3963, 'being stripped bare' for being deprived of truth, 1073, 4958, 5433, 'girding [sackcloth] around one's waist' for suffering grief over good that has been lost, 'beating on breasts' for suffering grief over the good of truth that has been lost. Since these things are meant, it also says 'for the fields of unmixed wine, and the fruitful vine'; for 'the field' is the Church in respect of good, thus the Church's good, 2971, 3196, 3310, 3766, and 'vine' is the spiritual Church, and therefore the good of truth, 5113, 6375, 6376.

[7] In the Book of Revelation,

I saw seven golden lampstands, and in the midst of the seven lampstands one like the Son of Man, clothed with a long robe, and surrounded by a golden girdle around the breasts. Revelation 1:12-13.

'Golden lampstands' are truths of good, 'the Son of Man' is Divine Truth, 'surrounded by a golden girdle around the breasts' the good of love. Anyone may deduce from the holiness of the Word that the things John saw concealed within themselves realities such as belong to the Lord's kingdom and His Church; for what holiness would there be in making predictions about kingdoms in the world? From this one may recognize that they are heavenly things that are meant by 'lampstands' and by 'the Son of Man, clothed with a long robe, and surrounded by a golden girdle around the breasts'.

[8] In Luke,

A certain woman lifted up her voice out of the crowd; ³ she said about Jesus, Blessed is the womb that carried You, and the breasts that You sucked. But Jesus said, Rather than that, blessed are those who hear the Word of God and keep it. Luke 11:27-28.

The Lord's reply shows what 'blessed is the womb' and what 'the breasts' mean - 'those who hear the Word of God and keep it', thus affections for truth which exist with those who hear the Word or God, and affections for good which exist with those who keep it, that is, put it into practice.
