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.

6637. 'These are the names of the children of Israel' means the essential nature of the Church. This is clear from the meaning of' the name as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2628, 2724, 3006, 3421; from the representation of 'the sons of Israel' as spiritual truths, dealt with in 5414, 5879, 5951; and from the representation of 'Israel' as the good of truth, which is spiritual good, dealt with in 3654, 4598, 5803, 5806, 5812, 5817, 5819, 5826, 5833. Since Israel' represents the good of truth or spiritual good and 'his sons' represent spiritual truths in the natural, 'the sons of Israel' also represent the Church, for what makes it the Church is spiritual good and the truths that spring from that good. A person without spiritual good, that is, the good of charity, and without spiritual truths, that is, the truths of faith, does not belong to the Church in spite of having been born within the Church. The whole of the Lord's heavenly kingdom possesses the good of love and faith, and unless the Church possesses good like that it cannot be the Church since it is not joined to heaven; for the Church is the Lord's kingdom on earth.

[2] The term 'Church' is not used because it is the place where the Word is and teachings drawn from it, or because it is where the Lord is known and the sacraments are celebrated. Rather it is the Church because it lives in accordance with the Word or with teachings drawn from the Word, and seeks to make those teachings its rule of life. People who do not live like this do not belong to the Church but are outside it; and those who lead wicked lives, thus lives contrary to that teaching, are further away outside the Church than gentiles who know nothing whatever about the Word, the Lord, or the sacraments. For since those people are acquainted with the forms of good that the Church fosters and with the truths it teaches they annihilate the Church within themselves, something gentiles cannot do because they are unacquainted with those things. It should also be realized that everyone who leads a good life, in charity and faith, is a Church, and is a kingdom of the Lord. He is for that reason also called a temple, and a house of God too. Those who are Churches individually, no matter how remote from one another they may be, constitute one Church collectively. This then is the Church meant by the expression 'the children of Israel' here and in what follows.

10453. 'And the tablets were the work of God, and the writing was the writing of God, engraved on the tablets' means the outward sense of the Word and the inward - which come from the Divine - and Divine Truth. This is clear from the meaning of 'the tablets' as the Word in its entirety, dealt with immediately above in 10452, but at this point the outward form of the Word, dealt with below; from the meaning of 'the work of God' as its coming from the Divine; from the meaning of 'the writing' as the inward form of the Word, also dealt with below, so that 'the writing of God' is the inward form of the Word coming from the Divine, and thus is Divine Truth; and from the meaning of 'engraved on the tablets' as the inward impressed on and so contained within the outward.

[2] The reason why the tablets here mean the outward form of the Word is that they are distinguished here from the writing, which is its inward form; but when they are not distinguished from the writing they mean the inward and the outward forms of the Word together, thus the Word in its entirety, as above in 10452. They are distinguished here because these tablets were broken, but nevertheless the same words were afterwards inscribed by Jehovah on the other tablets which were hewn by Moses. The outward form of the Word is its literal sense, the inward form is its internal sense. The former - the literal sense - is meant by 'the tablets', because this sense is like a tablet or level surface on which the internal sense is inscribed.

[3] The breaking by Moses of the tablets which were the work of God, when he saw the calf and the dances, and the hewing by Moses, as commanded by Jehovah, of other tablets, which then had the same words inscribed on them (so that the tablets were no longer the work of God but the work of Moses, though the writing was still the writing of God), hold an arcanum unknown up to now. The arcanum is that the literal sense of the Word would have been different if the Word had been written among another people, or if the character of the Israelite people had not been such as it was. For the literal sense of the Word is all about that people since the Word was written among them, as is evident from both the historical sections and the prophetical parts of the Word. They were a people steeped in evil because they were idolatrous at heart; yet in order that the internal sense and the external sense might be in agreement that people had to be highly acclaimed, and to be called God's people, a holy nation, and a peculiar treasure. Consequently the simple, who would be taught by means of the outward sense of the Word, would believe that that nation was all those things, as that nation itself also believes, and indeed as the majority in the Christian world do at the present day. Most of the things furthermore that present themselves in and constitute the outward sense of the Word were ones that were permitted on account of their hardness of heart, such as those referred to in Matthew 19:8 and also others which need not be mentioned here.

[4] Since therefore the literal sense of the Word came to be what it was because of what those people were like, the tablets which were the work of God were broken and others, as commanded by Jehovah, were hewn by Moses. But since they nevertheless had the same holy and Divine content within them the same words as were on the first tablets were inscribed by Jehovah on them, as is evident from the following verses in Moses,

Jehovah said to Moses, Hew for yourself two tablets of stone like the first ones, and I will write on the tablets the words that were on the first tablets which you broke. And Jehovah wrote on those tablets the words of the covenant, the Ten Words. Exodus 34:1, 4, 28.

And elsewhere,

At that time Jehovah said to me, Hew for yourself two tablets of stone like the first ones, and I will write on the tablets the words that were on the first tablets which you broke. And Jehovah wrote on the tablets according to the first writing, the Ten Words. Afterwards Jehovah gave them to me. Deuteronomy 10:1-4.

[5] The fact that Jehovah did not acknowledge that people as His own people - even though they were called such so that the inward sense would accord with the outward - but as Moses' people is clear from the present chapter,

Your people have corrupted themselves, whom you caused to come up out of the land of Egypt. Go! lead the people to what I have spoken of to you. Exodus 32:7, 34.

And further on,

And Jehovah spoke to Moses, Go up, you and the people whom you have caused to come up out of the land of Egypt, to the land of which I swore to Abraham, Isaac, and Jacob. And I will send an angel before you, for I will not go up in your midst because you ¹ are a stiff-necked people. Exodus 33:1-3.

[6] The like is meant by Moses' being put in the hole of the rock, and his not being allowed to see Jehovah's face, but only His back parts, Exodus 33:22-23. The like is also meant, when the skin on Moses' face shone, by his putting a veil onto his face whenever he talked to the children of Israel, Exodus 34:30-35. What the character of that people would be is foretold by Jehovah to Abram, when he wanted his seed to inherit the land of Canaan, where it is stated that after Abram had parted down the middle the three year old heifer, the three year old she-goat, and the three year old ram, which served for entering into a covenant,

A deep sleep came over Abram, and behold, a dread of a great darkness was coming over him. And when the sun went down there was thick darkness, and behold, a smoking furnace, and a flaming torch which passed between these pieces. Genesis 15:8, 9, 12, 17.
