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.

2910. 'And Abraham came to mourn for Sarah and to weep for her' means a state in which the Lord grieved, that is to say, because it was night as regards the truths of faith within the Church. This is clear from the representation of 'Abraham' as the Lord, dealt with in 1893, 1965, 1989, 2011, 2172, 2501, 2833, 2836. That 'mourning' and 'weeping' mean a state involving grief is clear without explanation. 'Mourning' has regard to grief on account of its being night as regards goods within the Church, and 'weeping' as regards truths. These two verses have dealt with the end of the Church, which arrives when charity does not exist any longer. The end of the Church is the subject many times in the Word, especially in the Prophets and in John, in the Book of Revelation. The Lord too in the Gospels describes that end extensively, calling it the close of the age, and also night.

[2] The situation with all Churches is that initially every Church regards charity as being fundamental. At that time every individual person loves every other as his brother and is moved by good - not on his own account but on account of that person, of the general good of all, of the Lord's kingdom, and above all of the Lord Himself. But with the passage of time charity starts to grow cold and to cease to exist. After that, hatred of one person against another enters in, which - though not apparent outwardly because people in organized society are subject to laws and to external restraints which keep them in check - is nevertheless being fostered inwardly. The external restraints keeping them in check stem from self-love and love of the world, being the love of position and importance, the love of wealth and also of the power that wealth brings, and so the love of reputation. Beneath these loves there lurks hatred of the neighbour, such as leads people to desire dominion over all and to possess everything that belongs to anyone else. And when these desires are opposed, such persons harbour in their mind contempt for that neighbour, breathe revenge, and take delight in his ruin, and indeed perform acts of cruelty on him insofar as they dare. It is into ways such as these that the charity of the Church ultimately goes when it reaches its end. At that time it is said of the Church that faith does not exist any longer, for when there is no charity there is no faith, as has been shown many times.

[3] There have been many Churches, which are known of from the Word, that have come to an end in this fashion. The Most Ancient Church breathed its last in such circumstances around the time of the Flood. So in a similar way did the Ancient Church which existed after the Flood, as also did the second Ancient Church called the Hebrew Church; and later on the Jewish Church. This never was a Church that had charity at the outset, but was merely the representative of a Church whose role was to preserve by means of representatives a communication with heaven until the Lord came into the world. After that a new Church was established by the Lord, which was called the gentile Church and was an internal Church since interior truths from the Lord had then been revealed. But even this Church has now reached its end, for now not only is charity non-existent but also hatred is present instead of charity. Although that hatred is not apparent outwardly it is nevertheless there inwardly and breaks out when at all possible, that is, as often as external restraints do not keep people in check.

[4] In addition to these Churches there have been many others which have not been described so specifically [in the Word] but which deteriorated in a similar way and destroyed themselves. There are many reasons why they have so deteriorated and destroyed themselves. One reason is that parents pile up evils, and from practicing these frequently until at length they become habitual, introduce them into their own nature and disposition, and in so doing hand them down by heredity to their offspring. For what parents acquire through frequent practice in their actual living takes root within their natural disposition and is transmitted by heredity to their descendants. And unless these are reformed or regenerated, that which is transmitted is perpetuated in succeeding generations, increasing all the time as it is passed down. Consequently the will becomes even more bent on evils and falsities. But when the Church reaches its close and perishes the Lord always raises up a new Church somewhere else. Yet rarely, if ever, has He done so from members of the previous Church, but from gentiles who dwelt in ignorance. Those gentiles are the subject in what follows next.

4735. 'Do not shed blood' means not to do violence to what is holy. This is clear from the meaning of 'blood' as that which is holy, dealt with below, and therefore 'shedding blood' means doing violence to it. Everything holy in heaven proceeds from the Lord's Divine Human, as consequently does everything holy in the Church. For this reason to prevent people from doing violence to that which is holy the Lord instituted the Holy Supper, in which it is explicitly declared that the bread there is His flesh and the wine His blood, thus that His Divine Human is the source of that which is holy in the Holy Supper. Among the Ancients 'flesh and blood' meant the human proprium, for that which is human consists of flesh and blood. This explains what the Lord said to Simon,

Blessed are you, for flesh and blood has not revealed this to you, but My Father who is in heaven. Matthew 16:17.

Therefore the flesh and blood meant in the Holy Supper by the bread and wine are the Lord's Human Proprium. The Lord's actual Proprium which He acquired to Himself by His own power is Divine. His Proprium was since His conception that which He had from Jehovah His Father and was Jehovah Himself, and therefore the Proprium which He acquired to Himself within the Human was Divine. It is this Divine Proprium within the Human that is called flesh and blood, 'flesh' being His Divine Good, 3813, 'blood' Divine Truth that goes with Divine Good.

[2] The Lord's Human, now that it has been glorified or made Divine, cannot be thought of as something merely human but as Divine Love within a human form. This is more true of Him than it is of angels, who - when they come to be seen, as I myself have seen them - are seen as forms of love and charity taking on a human appearance, the Lord enabling this to be so. For it was by Divine Love that the Lord made His Human Divine, even, as has been stated, as heavenly love serves to make someone an angel after death, so that he too is seen as a form of love and charity taking on a human appearance. From this it is evident that in the celestial sense the Lord's Divine Human means Divine Love itself, which is a love directed towards the whole human race whom He wishes to save, making them blessed and happy for ever, and to whom He wishes to impart, insofar as its members can accept it, what is His and is Divine, so that it becomes their own. This love, and man's reciprocated love to the Lord as well as his love towards the neighbour, are meant and represented in the Holy Supper, Divine celestial love by the flesh or bread in it and Divine spiritual love by the blood or wine.

[3] From all this one may now see what is meant by eating the Lord's flesh and drinking His blood in John,

I am the living bread which came down from heaven. If anyone eats of this bread he will live for ever. But the bread which I shall give is My flesh. Truly, truly, I say to you, Unless you eat the flesh of the Son of Man and drank His blood you will have no life in you. He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day. For My flesh is truly food, and My blood is truly drink. He who eats My flesh and drinks My blood abides in Me, and I in him. This is the bread which came down from heaven. John 6:50-58.

Because 'flesh' and 'blood' mean the Divine Celestial and the Divine Spiritual that proceed from the Lord's Divine Human, as has been stated, or what amounts to the same, mean Divine Good and Divine Truth that proceed from His Love, 'eating' and 'drinking' mean making these things one's own. They become one's own through the life of love and charity which is also the life of faith. For 'eating' means making good one's own, and 'drinking' making truth one's own, see 2187, 3069, 3168, 3513, 3596, 3734, 3832, 4017, 4018.

[4] Because 'blood' in the celestial sense means the Divine Spiritual or Divine Truth proceeding from the Lord's Divine Human, it therefore means that which is holy, for Divine Truth proceeding from the Lord's Divine Human is Holiness itself. There is no other Holiness, nor any other source of it.

[5] As regards 'blood' meaning that Holiness, this may be seen from many places in the Word, of which let the following be quoted here: In Ezekiel,

Son of man, thus said the Lord Jehovih, Say to every bird of the air, to every wild animal of the field, Assemble and come, gather yourselves from all around to My sacrifice which I am sacrificing for you, a great sacrifice upon the mountains of Israel, so that you may eat flesh and drink wine. You will eat the flesh of the mighty, and drink the blood of the princes of the earth - rams, lambs, and he-goats, all of them fatlings of Bashan. And you will eat fat till you are glutted and drink blood till you are drunk, from My sacrifice which I will sacrifice for you. You will be glutted at My table with horse and chariot, with the mighty, and with every man of war. Thus will I set My glory among the nations. Ezekiel 39:17-21.

This refers to the calling together of all people to the Lord's kingdom, and specifically to the establishment of the Church among gentiles. 'Eating flesh and drinking wine' means making Divine Good and Divine Truth one's own, and so making one's own the Holiness which proceeds from the Lord's Divine Human. Is there anyone who cannot see that here in the references to their eating the flesh of the mighty and drinking the blood of the princes of the earth, and their being glutted with horse, chariot, the mighty, and every man of war, 'flesh' is not used to mean flesh nor 'blood' to mean blood?

[6] Similarly in John,

I saw an angel standing in the sun, who called out with a loud voice, saying to all the birds flying in mid-heaven, Come, gather yourselves together to the supper of the Great God, so that you may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses and those seated on them, and the flesh of all, free men and slaves, small and great. Revelation 19:17-18.

Can anyone ever understand these things unless he knows what 'flesh' means in the internal sense, or what 'kings', 'captains', 'mighty men', 'horses', 'those seated on them', 'free men and slaves' mean?

[7] Also in Zechariah,

He will speak peace to the nations; His dominion will be from sea to sea, and from the River even to the ends of the earth As for you also, through the blood of your covenant I will let out your bound ones from the pit. Zechariah 9:10-11.

This refers to the Lord. 'The blood of the covenant' is Divine Truth proceeding from His Divine Human and is the Holiness itself which has gone out from Him since He was glorified. This Holiness is that which is also called the Holy Spirit, as is evident in John,

Jesus said, If anyone thirsts let him come to Me and drink. Whoever believes in Me, as the Scripture has said, Out of his belly will flow rivers of living water. This He said about the spirit which those believing in Him were to receive; for the Holy Spirit was not yet because Jesus was not yet glorified. John 7:37-39.

As regards the holiness proceeding from the Lord being 'the spirit', see John 6:63.

[8] Further to 'blood' meaning the holiness proceeding from the Lord's Divine Human - in David,

From deceit and from violence He will redeem ¹ their soul, and precious will their blood be in His eyes. Psalms 72:14.

'Precious blood' stands for the holiness which they are to receive. In John,

These are they who are coming out of the great tribulation, and have washed their robes, and have made their robes white in the blood of the Lamb. Revelation 7:14.

And in the same author,

They have conquered the dragon by the blood of the Lamb and by the Word of their testimony; and they did not love their soul even to death. Revelation 12:11.

[9] The Church at the present day knows no more than this, that 'the blood of the Lamb' here means the Lord's passion, for it believes that people are saved solely through the Lord's passion and that it was to endure this that He was sent into the world, a belief which may be enough for the simple who are incapable of grasping interior arcana. The Lord's passion was the last stage of His temptation, by which He fully glorified His Humanity, Luke 24:26; John 12:23, 27-28; 13:31-32; 17:1, 4-5. But 'the blood of the Lamb' here in Revelation is the same as the Divine Truth or that which is holy proceeding from His Divine Human, and so is the same as 'the blood of the covenant' referred to just above, and also in Moses,

[10] Moses took the book of the covenant, and read it in the ears of the people, who said, All that Jehovah has spoken we will do and hear. Then Moses took the blood and sprinkled it over the people. and said, Behold the blood of the covenant which Jehovah has made with you, upon all these words. Exodus 24:7-8.

'The book of the covenant' was Divine Truth as it existed with them at that time, which Truth was corroborated by means of the blood that bore witness to the fact that such Truth proceeded from His Divine Human.

[11] In the ritual requirements of the Jewish Church 'blood' meant nothing other than the holiness proceeding from the Lord's Divine Human. When people were being consecrated blood was therefore used to effect this, as when Aaron was consecrated along with his sons. At that time the blood was sprinkled over the horns of the altar, the residue being poured out at the base of it. Some was also put on the tip of their right ear, on their right thumb and the big toe of their right foot, and on their vestments, Exodus 29:12, 16, 20-21; Leviticus 8:15, 19, 23, 30. And when Aaron went within the veil to the mercy-seat the blood had also to be sprinkled with his finger seven times over the east side of the mercy-seat, Leviticus 16:12-15. Likewise in all other consecrations, as well as expiations and cleansings, mentioned in Exodus 12:7, 13, 22; 30:10; Leviticus 1:5, 11, 15; 3:2 , 8, 13; 4:6-7, 17-18, 25, 30, 34; 5:9; 6:27-28; 14:14-19, 25-30; 16:12-15, 18-19; Deuteronomy 12:27.

[12] As 'blood' in the genuine sense means that which is holy, so in the contrary sense 'blood' and 'bloods' mean things which bring violence to it. This is because 'shedding innocent blood' means doing violence to that which is holy. For the same reason too infamous deeds in life and profane acts of worship are called 'blood'. The fact that such things are meant by 'blood' and 'bloods' is clear from the following places: In Isaiah,

When the Lord will have washed the excrement of the daughters of Zion and washed away the blood of Jerusalem from its midst by a spirit of judgement and by a spirit of purging. Isaiah 4:4.

In the same prophet,

The waters of Dimon are full of blood. Isaiah 15:9.

In the same prophet,

Your hands are defiled with blood, and your fingers with iniquity. Their feet run to evil, and they hasten to shed innocent blood; their thoughts are thoughts of iniquity. Isaiah 59:3, 7.

In Jeremiah,

Yes, in your skirts the blood of poor innocent souls is found. Jeremiah 2:34.

[13] In the same prophet,

For the sins of the prophets, the iniquities of the priests who shed in the midst of Jerusalem the blood of the righteous. They went astray blind in the streets, they are defiled with blood. Things which have no power they touch with their garments. Lamentations 4:13-14.

In Ezekiel,

I passed by you and saw you weltering in your blood, ² and I said to you, Live in your blood; ² I indeed said to you, Live in your blood'. I washed you with water and washed away your blood ² from upon you, and anointed you with oil. Ezekiel 16:6, 9.

In the same prophet,

You, son of man, will you dispute with the city of blood? ² Declare to her all her abominations. By your blood which you have shed you have become guilty, and by the idols which you have made you are defiled. Behold, the princes of Israel, each according to his power, ³ have been among you and have shed blood. Men of intrigue have been among you, [ready] to shed blood, and among you have eaten on the mountains. Ezekiel 22:2-4, 6, 9.

In Moses,

If anyone sacrifices anywhere else than on the altar at the tent of meeting it shall be [regarded as] blood, and as though he had shed blood. Leviticus 17:1-9.

[14] Truth that has been falsified and rendered profane is meant in the following references to 'blood': In Joel,

I will give portents in the heavens and on earth, blood and fire, and columns of smoke. The sun will be turned into thick darkness, and the moon into blood, before the great and terrible day of Jehovah comes. Joel 2:30-31.

In John,

The sun became black as sackcloth made of hair, and the full moon became like blood. Revelation 6:12.

In the same author,

The second angel sounded, and as it were a great mountain burning with fire was thrown into the sea, and a third part of the sea became blood. Revelation 8:8.

In the same author,

The second angel poured out his bowl into the sea, and it became like the blood of one dead, from which every living soul died in the sea. The third angel poured out his bowl into the rivers and into the fountains of water, and blood was made. Revelation 16:3-4.

[15] A similar meaning occurs in the turning of the rivers, pools and ponds in Egypt into blood, Exodus 7:15-22, for 'Egypt' means knowledge which enters of its own accord into heavenly arcana and as a consequence perverts Divine truths, refuses to accept them, and renders them profane, 1164, 1165, 1186. Being Divine ones, all the miracles performed in Egypt embodied the same kind of meanings. 'The rivers' which were turned into blood means the truths that go with intelligence and wisdom, 108, 109, 3051, as likewise do 'waters', 680, 2702, 3058, and 'springs', 2702, 3096, 3424. 'Seas' means factual truths taken as a single whole, 28. 'The moon', which, it is also said, is to be turned into blood, means Divine Truth, 1529-1531, 2495, 4060. From this it is evident that the turning of the moon, sea, springs, waters, and rivers into blood means Truth that has been falsified and rendered profane.
