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.

3773. 'And they would put the stone back in its place over the mouth of the well' means that it was closed up for the time being. This is clear from what has been stated about the stone over the mouth of the well, in 3769, 3771. With regard to these considerations, namely that the Word was uncovered for the Churches and after that closed up, the position is that in the beginning, when any Church is established, the Word is in that initial period closed up to them but later on, through the Lord's provision, is opened up. And from there people learn that all doctrine is based on these two commandments, that the Lord is to be loved above everything else, and the neighbour as themselves. When these two commandments are the end in view the Word is in that case opened up, for all the Law and all the Prophets, that is, the whole of the Word, hangs on them, as does everything from them, and so everything has reference to them. And being in that case governed by the primary teachings concerning truth and good people receive light in each particular thing they see in the Word. For the Lord is present with them at that time by means of angels and is teaching them even though they are not directly aware of it, and is also guiding them into the life of truth and good.

[2] This may also be seen from the consideration that in their infancy all Churches have been such, and have from love worshipped the Lord, and have from the heart loved the neighbour. But in course of time Churches have moved away from these two commandments, and have turned away from good flowing from love and charity towards those things called matters of faith, and so have turned away from life towards doctrine. And to the extent this happens the Word is closed up. These are the factors meant in the internal sense by the words, 'Behold, a well in the field, and behold, three droves of a flock there, lying nearby it; for out of that well they watered the droves; and there was a large stone over the mouth of the well. And all the droves would be gathered there; and they would roll the stone from over the mouth of the well and water the flock; and they would put the stone back in its place over the mouth of the well'.

3986. 'And Jehovah has blessed you since I set foot here' means resulting from the Divine endowment which the natural possessed. This is clear from the meaning of 'Jehovah blessing' as being endowed with good, dealt with in 3406, and as a joining together, 3504, 3514, 3530, 3565, 3584. 'Jehovah blessing' accordingly means being endowed with Divine good by means of a joining together, at this point a joining to the good of the natural represented by 'Jacob', the natural being meant by 'the foot'. As regards 'the foot' meaning the natural, see 2162, 3147, 3761; and this will be clear in addition from the correspondence of the Grand Man with every part of the human being, the subject in the sections at the ends of chapters. From this it is evident that 'Jehovah has blessed you since I set foot here' means originating in the Divine which the natural possessed.

[2] The arcanum which lies concealed in these words and in those immediately before them is known to few, if any, and is therefore to be revealed. The goods present with people both inside the Church and outside it vary in every case. They vary so much that no one person's good is ever exactly like another's. These variations arise out of the truths to which those goods are joined, for the nature of every type of good is received from truths, and truths derive their essential nature from goods. Such variations also arise out of the affections that belong to each person's love, and which become rooted in a person and are made his own through the life he leads. Few genuine truths exist even with someone inside the Church, and fewer still with one outside. Consequently affections for genuine truth seldom exist with anyone.

[3] All the same, people who lead good lives, that is, who live in love to God and in charity towards the neighbour, are saved. The reason they are able to be saved is that the Lord's Divine is present within good that stems from love to God and within good that stems from charity towards the neighbour. And when the Divine is inwardly present everything is being arranged into order so that it can be joined to genuine goods and genuine truths which exist in the heavens. The truth of this may be proven from the communities constituting heaven, which are countless. Every single community varies as regards good and truth, and yet all of them taken together form one complete heaven. They are like the members and organs of the human body which, though varying in every case, still constitute one complete human being. For no complete whole is ever made up of any identical or entirely similar individual parts, but of varying parts harmoniously joined together. Varying parts joined together harmoniously present a single whole. The same applies to goods and truths in the spiritual world. Although these vary so much as never to be exactly similar with one person as with another, nevertheless from the Divine through love and charity they make one since love and charity are spiritual conjunction. Their variation is a heavenly harmony which produces such accord that they are one in the Divine, that is, in the Lord.

[4] Furthermore, however much truths may vary, and however much affections for truth may do so, good that stems from love to God and good that stems from charity towards the neighbour are nevertheless capable of receiving genuine truth and good, as they are not so to speak hard and resistant but soft and yielding. They allow themselves to be led by the Lord and in so doing to be turned towards good, and through good to be turned towards Him. It is different with those in whom self-love and love of the world reign. They do not allow themselves to be led and turned by the Lord towards the Lord but strongly resist, since each wishes to be his own leader, even more so when they have become subject to false and firmly established assumptions. As long as they are such they do not allow the Divine to come in.

[5] These considerations now make clear what is meant in the internal sense by these words which Jacob addressed to Laban, for 'Laban' means the kind of good which is not genuine because it does not have genuine truths planted within it but is nevertheless capable of having these joined to it and of having the Divine present within it. This kind of good is what normally exists with young children before they have received genuine truths. It is also the kind of good present with simple people within the Church who know few truths of faith but who nevertheless lead a charitable life. It is in addition the kind of good present with upright gentiles who offer holy worship to their gods. By means of such good, genuine truths and goods are able to be introduced, as may be seen from what has been stated about young children and simple people inside the Church in 3690, and about upright gentiles outside the Church in 2598-2603.
