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.

2982. 'In the land of Canaan' means which was a united whole in the Lord's kingdom. This is clear from the representation of 'the land of Canaan' as the Lord's kingdom, dealt with in 1413, 1437, 1585, 1607. With the Lord's Churches the position is that in ancient times many existed simultaneously. These differed from one another, as Churches do today, on matters of doctrine, but they still made one in that they acknowledged love to the Lord and charity towards the neighbour as the chief and most essential thing. And so to them matters of doctrine existed not so much to guide their thought as to direct their lives. And when in every single respect love to the Lord and charity towards the neighbour, that is, the good of life, is the essential thing, then no matter how many Churches there are they all make one, and each is a united whole in the Lord's kingdom. The same is also true of heaven. Although there are countless communities there, and each one is distinct and separate from the rest, they nevertheless all constitute one heaven because every one is moved by love to the Lord and charity towards the neighbour.

[2] But the situation is altogether different in the case of Churches which say that faith is the essential thing of the Church, for they imagine that if they know this and think it, they are saved irrespective of whatever kind of life they lead. When this is the situation many Churches existing simultaneously do not make one Church; they are not even Churches. The good of faith is what makes the Church, that is, the life of love and charity in accordance with matters of faith make it. It is for the sake of life that matters of doctrine exist. This anyone may know, for why does any doctrine exist if not for some end in view? And what else is that end but life, that is, that a person may become as such doctrine teaches? Those Churches do indeed speak of saving faith as being trust, but that trust cannot possibly exist except within the good of life. Without the latter there is no receptivity, and when there is no receptivity there is no trust, except on occasions when the mind or body is sick and the desires that belong to self-love and love of the world are dormant. But with those who are leading an evil life, when this crisis is over or takes a different turn, that spurious trust disappears altogether; for trust can exist even with those who are evil. But if a person wishes to know what kind of trust he has, let him examine his affections and ends in view, and also the kind of life his actions reveal.

7004. 'And to put words in his mouth' means that the things he utters will go forth from the Divine Human. This is clear from the representation of 'Moses', who was to put words in Aaron's mouth, as the Lord's Divine Truth which goes forth from His Divine Human, dealt with already; and from the meaning of 'mouth' as voice and utterance, dealt with above in 6987, so that 'putting in the mouth' means giving to utter. But when the phrase is used in reference to the Lord it means to go forth, for the Word, uttered by a spirit or angel, goes forth from the Lord's Divine Human. For 'Aaron' represents teachings that present what is good and true, which are given utterance.

[2] The implications of all this are that from the Lord Divine Truth goes forth in direct and indirect ways. What goes forth directly is entirely beyond angels' power of understanding; but what goes forth by an indirect way is fully suited to angels in heaven and also to men on earth, for the way it takes passes through heaven and by going this way it takes on a nature appropriate for angels and a nature appropriate for men. But the Lord also flows directly into this truth and thereby leads angels and men not only indirectly but also directly, see 6058. For everything in general and in particular owes its existence to the Primary Being (Esse), and established order is such that the Primary Being in things derived from it is present indirectly and directly, and so is present in the last and lowest degree of order no less than in the first. For the Divine Truth itself is altogether the substance, whereas the things derived from it are nothing else than the subsequent forms that are given to that substance. From this it is also evident that the Divine also flows directly into every single thing; for all things have been created by Divine Truth, because Divine Truth is altogether the essence, 6880, and so is that from which all things receive their being. Divine Truth is what is called 'the Word' in John,

In the beginning was the Word, and the Word was with God, and the Word was God. All things were made through Him, and without Him nothing was made that was made. John 1:1, 3.

Through this kind of inflowing the Lord leads a person not only by the operation of His providence in a general way but also in every specific way, indeed in the most specific of all. This then is the reason why it is said that the things that are uttered will go forth from the Divine Human.

[3] I have been told from heaven, and led to perceive from actual experience, that the Lord flows in directly when He also does so indirectly, and so is present in the last and lowest degree of order no less than in the first. I have in addition been told and led to perceive that comparatively little is accomplished by indirect influx, that is, by influx through heaven and the angels there, and also that by direct influx the Lord simultaneously leads heaven and keeps every single thing there properly connected and ordered.
