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.

4672. 'And he, still a boy' means at first. This is clear from the meaning of 'a boy' - when this expression is used to refer to a new Church - as at first, that is, as the first state of that Church. For the Church is like an infant, a boy, a man, and at length an old man, in that it passes as the individual does through its own phases of life. The Church also resembles the human being in general, and is actually called one. Furthermore, within the Church which is called 'a boy' because of the phase it is at, and which is by nature such that it soon becomes wayward, the Lord is present at first, both with those who teach and those who learn. But after a while they dissociate themselves from Him, as is also represented by the brothers throwing Joseph into the pit and selling him.

[2] Every Church which begins with faith is like this, but a Church beginning with charity is different. A Church that begins with faith is controlled solely by the understanding, and the understanding by that which has been inherited, namely self-love and love of the world. These loves induce the understanding to gather texts from the Word which support their desires, and to give its own interpretation to those which do not support them. It is different in the case of a Church which begins with charity. This Church is controlled by good, the Lord being within that good. For good which is the good of charity and love is a mediator between the Lord and faith; and unless it is there as a mediator between them no spiritual communication is possible. Without that intermediary He cannot possibly flow into faith. If evil exists there instead of good it drives away the Lord and casts aside or else perverts everything that is the Lord's and so the whole of faith; for faith comes from Him through good.

246. FROM THE ARCANA COELESTIA.

The church exists specifically where the Word is, and where the Lord is thereby known, and thus where Divine truths are revealed (n. 3857, 10761). Still they who are born where the Word is, and where the Lord is thereby known, are not of the church, but they who are regenerated by the Lord by the truths of the Word, that is, they who live the life of charity (n. 6637, 10143, 10153, 10578, 10645, 10829). They who are of the church, or in whom the church is, are in the affection of truth for the sake of truth, that is, they love truth because it is truth; and they examine from the Word whether the doctrinals of the church in which they were born are true (n. 5432, 6047). Otherwise the truth possessed by everyone would be derived from another, and from his native soil (n. 6047).

The church of the Lord is with all in the whole world who live in good according to their religious principles (n. 3263, 6637, 10765). All who live in good wherever they are, and acknowledge one God, are accepted by the Lord and come into heaven; since all who are in good acknowledge the Lord, because good is from the Lord, and the Lord is in good (n. 2589-2604, 2861, 2862, 3263, 4190, 4197, 6700, 9256). The universal church on earth before the Lord is as one man (n. 7396, 9276). As heaven is, because the church is heaven or the kingdom of the Lord on earth (n. 2853, 2996, 2998, 3624-3629, 3636-3643, 3741-3745, 4625). But the church, where the Lord is known and where the Word is, is like the heart and lungs in man in respect to the other parts of the body, which live from the heart and lungs as from the fountains of their life (n. 637, 931, 2054, 2853). Hence it is, that unless there were a church where the Word is, and where the Lord is thereby known, the human race could not be saved (n. 468, 637, 931, 4545, 10452). The church is the foundation of heaven (n. 4060).

The church is internal and external (n. 1242, 6587, 9375, 9680, 10762). The internal of the church is love to the Lord and charity towards the neighbor. Thence they who are in the affection of good and truth from love to the Lord and from charity towards the neighbor, constitute the internal church; and they who are in external worship from obedience and faith, constitute the external church (n. 1083, 1098, 4288, 6380, 6587, 7840, 8762). To know truth and good, and to act from thence, is the external of the church, but to will and love truth and good, and to act from thence, is the internal of the church (n. 4899, 6775). The internal of the church is in the worship of those who are of the external church, although in obscurity (n. 6775). The internal and external church make one church (n. 409, 10762). Man has an internal and an external, an internal after the image of heaven, and an external after the image of the world; and therefore, in order that the man may be a church, his external must act in unity with his internal (n. 3628, 4523-4524, 6057, 6314, 9706, 10472). The church is in the internal of man and at the same time in the external, but not in the external without the internal (n. 1795[1-2], 6580, 10691). The internal of the church is according to truths and their quality, and according to their implantation in good by life (n. 1238).

The church like heaven is in man, and thus the church in general consists of the men in whom the church is (n. 3884). In order that a church may exist, there must be the doctrine of life, that is, the doctrine of charity (n. 3445, 10763-10764). Charity makes the church, and not faith separated from charity (n. 916). Consequently, not the doctrine of faith separated from charity, but the doctrine of faith conjoined therewith, and a life conformable to it (n. 809, 1798-1799, 1834, 1844, 4468, 4672, 4689, 4766, 5826, 6637). The church is not with man, unless the truths of doctrine are implanted in the good of charity with him, thus in the life (n. 3310, 3963, 5826). There is no church with man, if he is only in the truths, which are called the truths of faith (n. 5826). How much good would be in the church, if charity were in the first place and faith in the second (n. 6269). And how much evil, if faith is in the first place (n. 6272). In the ancient churches charity was the principal and essential of the church (n. 4680). The church would be like heaven, if all had charity (n. 2385, 2853). If good were the characteristic of the church, and not truth without good, thus if charity were its characteristic, and not faith separate, the church would be one, and differences with respect to the doctrinals of faith, and external worship, would be accounted as nothing (n. 1285, 1316, 2982, 3267, 3445, 3451).

Every church begins from charity, but declines therefrom in process of time (n. 494, 501, 1327, 3773, 4689). Thus to falsities from evil, and at length to evils (n. 1834-1835, 2910, 4683, 4689). A comparison of the church at its beginning and decline with the infancy and old age of man (n. 10134). And also with the rising and the setting of the sun (n. 1837). Concerning the successive states of the Christian Church even to its last state; wherein are explained the particulars which the Lord foretold concerning "the consummation of the age," and His "coming," in Matt. chap. 24 from the beginning to the end (n. 3353-3356, 3486-3489, 3650-3655, 3751-3757, ¹ 3897-3901, 4057-4060, 4229-4231, 4332-4335, 4422-4424, 4635-4638, 4807-4810, 4954-4959, 5063-5071). The Christian church is at this day in its last states, there being no faith therein because there is no charity (n. 3489, 4689). The Last Judgment is the last time of the church (n. 2118, 3353, 4057, 4333, 4535). Of the vastation of the church (n. 407-411). The consummation of the age and the coming of the Lord is the last time of the old church and the beginning of the new (n. 2243, 4535, 10622). When the old church is vastated, interior truths are revealed for the service of the new church which is then established (n. 3398, 3786). Concerning the establishment of the church with the Gentiles (n. 1366, 2986, 4747, 9256).
