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.

2048. That 'he who is born in the houses means celestial people, and 'he who is the purchase of silver' spiritual people, and so those who are inside the Church, is clear from the meaning of 'him born in the house' as those inside the house. In the Word 'a house' means that which is celestial because this is inmost. Consequently 'the house of God' means in the universal sense the Lord's kingdom, in a less universal sense the Church, and in a particular sense the individual himself in whom the Lord's kingdom or Church exists. When a person is called 'a house' it means the celestial side of faith with him, but when he is called 'a temple' it means the truth of faith with him. So 'he who is born in the house' here means celestial people. That 'the purchase of silver' or one bought with silver means spiritual people however is clear from the meaning of 'silver' as truth, and so the spiritual side of faith, dealt with in Volume One, in 1551.

[2] The expression celestial is used of those who are governed by love to the Lord, and because the Most Ancient Church which existed before the Flood was governed by that love it was a celestial Church. The expression spiritual is used of those who are governed by love towards the neighbour and so by the truth of faith. This was the character of the Ancient Church that existed after the Flood. The difference between celestial people and spiritual has been dealt with many times in Volume One. Anyone may see that there are heavenly arcana here, that is to say, in the requirement to circumcise those born in the house and those bought with silver, also sons who were foreigners, and in the fact that those persons are mentioned repeatedly, for example, in verses 13, 23, 27, that follow. These arcana are not apparent however except from the internal sense, that is to say, that those born in the house and those bought with silver mean celestial people and spiritual, and so those inside the Church - while 'the son who is a foreigner and not of your seed' means those outside the Church.

9209. 'If you lend silver to [My] people, to the needy one with you' means giving instruction to those who have no knowledge of truth and still have a desire to learn it. This is clear from the meaning of 'silver' as truth, dealt with in 1551, 2048, 2954, 5658, 6112, 6914, 6917, 7999, 8932; from the meaning of 'lending' as communicating the good things of heaven in a spirit of charity and affection, dealt with in 9174, thus giving instruction; from the meaning of 'people' as those in possession of truths, in this instance those with no knowledge of truth since the people referred to are 'needy' (for the use of the word 'people' to mean those in possession of truths, see 1259, 1260, 2928, 3295, 3581, 7207); and from the meaning of 'the needy one' as those who have no knowledge of truth and still have a desire to learn it. For they are people in spiritual need and should be given instruction.

[2] The Word talks frequently about aiding the poor and needy. People in possession of external truths who have not yet been brought to internal truths believe that anyone at all in need of any kind of help should be aided, especially beggars who call themselves the poorest of all. Those who give such aid in a spirit of obedience, because they are commanded to act in that way, do well; for through that outward action they are brought to the inward aspect of charity and mercy. The inward aspect of charity and mercy consists in seeing clearly who exactly they are who should receive aid, what their character is, and in what way each is to be given it. Those who are brought eventually to the inward aspect of charity and mercy know that the inward aspect consists in desiring the welfare of and aiding the internal man, thus with gifts such as are beneficial to spiritual life, and that the outward aspect consists in aiding the external man, thus with gifts such as are beneficial to bodily life. But care must nevertheless always be taken to ensure that when aid is given to the external man, it is at the same time beneficial to the internal; for no one who aids the external but harms the internal is exercising charity. Therefore when one kind of aid is offered, the other must be kept in sight.

[3] The outward aspect of charity is what the external or literal sense of the Word describes when it says that aid should be given to the poor and needy, but the inward aspect of charity is what the internal or spiritual sense of the Word describes. For in the spiritual sense the internal man who is in a state of poverty and need and should be aided is meant, because in that sense 'the poor and needy' is used to mean those who lack good and have no knowledge of truth, and still have a desire for them. How these people are to be helped the letter of the Word also teaches, especially the Word taught by the Lord Himself when He was in the world. At that time the Lord revealed such things as have to do with the internal man, as is evident throughout the Gospels. Nevertheless He spoke in such a way that every detail had at the same time an inner meaning, intended for angels and at the same time for those in the internal Church. For the inner meaning contains such things as the authentic teachings of the Church present.

[4] Let what the Lord said to the disciples sent by John the Baptist to ask whether He was the One who must come serve to exemplify this,

Go and report to John the things you have seen and heard, that the blind see, the lame walk, lepers are cleansed, the deaf hear, the poor have the gospel preached to them. Luke 7:20, 22.

These words were spoken for the external man and at the same time for the internal man. For the external man they declared that such miracles were being performed, for the internal man that the Church is being established among the kind of people who in a spiritual sense are blind, lame, lepers, deaf, and poor, thus among gentiles who have no knowledge of good or truth, and still have a desire for them. For 'the blind' describes those who have no knowledge of truth, 6990; 'the lame' those who are governed by good, but not genuine good because they have no knowledge of truth, 4302; 'lepers' those who are unclean, and still have a desire to be made clean; and 'the deaf' those without any belief in truth because they have no perception of it.

[5] But 'the poor' describes those who do not possess the Word and so know nothing about the Lord, and still have a desire to receive instruction, which is why it says that the gospel is preached to them. By 'the poor and needy' are meant in the internal sense those outside the Church who have no knowledge of truth because they do not possess the Word, but nevertheless have a desire to receive instruction, and who by virtue of what they do know are governed still by a little good; also those within the Church who for one reason or another are ignorant of truth, but are still moved by some good to desire it. All this is clear from places in which 'the poor and needy' are mentioned in the Word, as in David,

I am needy and poor; make haste to me, O God! [You are] my help and my deliverer, O Jehovah. Psalms 70:5.

These words were spoken by David who was not poor and needy, from which it is evident that spiritual poverty and need were meant. Similar words occur elsewhere,

I am needy and poor, O Lord; remember me. [You are] my help and my deliverer. Psalms 40:17.

In the same author,

The king will judge Your people in righteousness, and Your needy ones in judgement. ¹ The mountains will bring peace to the people, and the hills, in righteousness. He will judge the needy ones of the people, save the children of the poor, and break in pieces the oppressor. Psalms 72:2-4.

'Needy ones' here are those who are in spiritual need and for that reason are hungry, that is, they have a desire to receive instruction in truths.

[6] In the same author,

Let all my bones say, O Jehovah, who is like You, delivering the needy from him who is too strong for him, and the needy and poor from those who despoil him? Psalms 35:10.

'Bones' are factual knowledge of truth, 8005. 'The needy' here stands for those with little truth, and 'the poor' for those with little good, who are molested by evils and falsities. Because of such molestation 'the needy' in the original language are also 'the afflicted'; for 'being afflicted' means being molested by falsities, 9196. Similarly in the same author,

The wicked lies in wait ² to catch the needy; he catches the needy and draws him into his net. Psalms 10:9.

In Isaiah,

Is not this the fast, to break bread for the hungry, and to bring into the house needy outcasts? Isaiah 58:6-7.

In the same prophet,

Jehovah has comforted His people, and will have mercy on His needy ones. Isaiah 49:13.

In Zephaniah,

I will leave in your midst a needy and lean people, who hope in the name of Jehovah. Zephaniah 3:12.

In these places 'the needy' are those who have no knowledge of truth and desire to receive instruction.
