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.

4723. 'They saw him from a distance' means the Lord's Divine Human perceived remotely. This is clear from the meaning of 'seeing' as perception, dealt with in 2150, 3764; from the meaning of 'from a distance' as remotely; and from the representation of 'Joseph' - the one they saw from a distance - as the Lord as regards Divine Truth, dealt with in 4669. The reason the Lord's Divine Human is what 'Joseph' is used to mean here is that His Divine Human is the highest aspect of Divine Truth. There are two essentials which constitute the Church and as a consequence it has two main teachings, the first being that the Lord's Human is Divine, the second that love to the Lord and charity towards the neighbour constitute the Church, not faith separated from these. Being the primary aspects of Divine Truth, these too are represented by 'Joseph'. Anyone who represents Divine Truth in general also represents the specific aspects of Divine Truth. But which specific aspect is represented at any point is evident from the train of thought.

3793. 'Rachel came with the flock' means the affection for interior truth belonging to the Church and to doctrine. This is clear from the representation of 'Rachel' as the affection for interior truth, and from the meaning of 'the flock' as the Church and also as doctrine, dealt with in 3767, 3768, 3783. To enable it to be known how 'Rachel' represents the affection for interior truth, and 'Leah' the affection for exterior truth, let a brief statement be made about the matter: The natural, which 'Jacob' represents, consists of good and of truth; and within the natural, as within every single part in the human being, and indeed within the whole natural order, there ought to be a marriage of good and truth. Without this marriage nothing is produced, for every act of bringing forth and every effect is from that marriage. When he is born there is no marriage of good and truth within a person's natural because the human being, unlike other creatures, is not born into a condition where Divine order is present. It is true that good which goes with innocence and charity is present, flowing from the Lord in earliest childhood; but no truth is present to which that good may be coupled. As he advances in life this good which has been instilled by the Lord into a person in early childhood is drawn in towards the interior parts and kept there by the Lord so that it may serve to modify the states of life which he experiences subsequently. As a consequence without the good belonging to his infancy and early childhood the human being would be worse and more vicious than any wild animal. When that good belonging to earliest childhood is drawn inwards, evil in that case takes its place and enters the person's natural. Falsity then couples itself to that evil, and a joining together and so to speak a marriage of evil and falsity takes place with him. If a person is to be saved therefore, he has to be regenerated. Evil has to be removed and good instilled by the Lord. And in the measure that he receives good truth is instilled into him so that a coupling, or so to speak marriage, of good and truth takes place.

[2] These are the matters represented by Jacob and his two wives, Rachel and Leah. 'Jacob' now takes on the representation of natural good therefore, and 'Rachel' that of truth. But since all joining of truth to good is effected through affection, it is the affection for truth coupled to good that 'Rachel' represents. Furthermore the natural, like the rational, has an interior and an exterior. 'Rachel' represents the affection for interior truth, and 'Leah' the affection for exterior truth. 'Laban', who is their father, represents a good that springs from a common stock, but is a parallel good, as has been stated. That good is the good which in the parallel line corresponds to the truth of the rational, which is 'Rebekah', 3012, 3013, 3077. Daughters descended from that good therefore represent affections existing within the natural, for these are like daughters fathered by that good. And because those affections are to be coupled to natural good they consequently represent affections for truth - the first representing the affection for interior truth, the second the affection for exterior truth.

[3] The regeneration of a person's natural is altogether like Jacob and Laban's two daughters, Rachel and Leah. Anyone therefore who can see and understand the internal sense of the Word sees this arcanum which has been disclosed to him, but no one else is able to see it except him in whom good and truth are present. No others, no matter how good a perception they may have of the things to do with personal life and life in society and may seem to be highly intelligent, are able to see and then to acknowledge anything at all of that arcanum. Indeed they do not know what good and truth are, for they imagine evil to be good, and falsity to be truth. For this reason the moment good is mentioned the idea of evil presents itself, and the moment truth is mentioned the idea of falsity does so. Consequently they perceive nothing of the things contained in the internal sense, but as soon as they hear anything of it darkness descends which extinguishes the light.
