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.

7091. 'Thus said Jehovah, the God of Israel' means that it - the admonition to those opposed to the Church's truths - comes from the Lord's Divine Human. This is clear from the consideration that 'Jehovah, the God of Israel' is used to mean the Lord in respect of the Divine Human, for 'Jehovah' in the Word is the Lord, see 1343, 1736, 2921, 3023, 3075, 5041, 5663, 6281, 6303, 6905. He is called 'the God of Israel' because the Lord's spiritual kingdom is meant by 'Israel', 6426, 6637, and because by His Coming into the world the Lord saved those who belonged to that kingdom or Church, 6854, 6914, 7075. The reason why 'the God of Israel' means the Lord in respect of the Divine Human is that those who belong to that Church envisage everything spiritual or celestial, and the Divine too, in the way they envisage natural things. Therefore if they did not think in a natural way of the Divine as a Person they could not be joined to the Divine through any kind of affection. For if they did not think about the Divine as a Person in a natural way they would have either no ideas at all about the Divine, or else monstrous ones, and so would defile the Divine. So this is why 'the God of Israel' is used to mean the Lord in respect of the Divine Human, in particular of the Divine Natural.

'Israel' and 'Jacob' are used in the highest sense to mean the Lord's Divine Natural, 'Israel' the internal Divine Natural and 'Jacob' the external Divine Natural, see 4570.

Those who belong to the spiritual Church have been and are saved by means of the Lord's Divine Human, 2833, 2834.

The member of the spiritual Church, who is 'Israel', is interior natural, 4286, 4401.

[2] From all this it is now evident why in the Word the Lord is called 'Jehovah, the God of Israel' and 'Jehovah, the Holy One of Israel'. Anyone may see that when the Divine is referred to by these names it is solely because they are suitable for expressing something Holy that is not apparent in the sense of the letter. The fact that the Lord in respect of the Divine Natural is meant by 'the God of Israel' is evident from quite a number of places in the Word, plainly so from the following,

Moses and Aaron, Nadab and Abihu, and the seventy elders of Israel saw the God of Israel, under whose feet there was so to speak a paved work of sapphire stone, like the substance of the sky for clearness. Exodus 24:9-10.

[3] The fact that this was the Lord, and not Jehovah, who is called the Father, is evident from the Lord's words in John,

Nobody has ever seen God. John 1:18.

You have never heard His voice nor seen His shape. John 5:37.

In Isaiah,

I will give you the treasures of darkness, and the secret wealth of concealed places, that you may know that it is I, Jehovah, who called you by your name, the God of Israel. Isaiah 45:3.

In Ezekiel,

Over the heads of the cherubim, in appearance like a sapphire stone, there was the likeness of a throne, and over the likeness of a throne there was a likeness, as the appearance of a man (homo) upon it above. And with him there was the appearance of fire and a rainbow, and of brightness round about. Ezekiel 1:26-28.

These things are called the glory of Jehovah and of the God of Israel in the same prophet, in Ezekiel 1:28; 8:4; 9:3; 10:19-20, and also where the New Temple is the subject, in Ezekiel 43:2; 44:2, [4]. ['The God of Israel' appears] in many other places besides these, such as Isaiah 17:6; 21:10, 17; 24:15; 41:17; Psalms 41:13; 59:5; 68:8, 35; 69:6; 72:18; and elsewhere. The name THE HOLY ONE OF ISRAEL is also used in Isaiah 1:4; 5:19, 24; 10:20; 17:7; 30:11-12, 15; 49:7; 60:9, 14; Ezekiel 39:7.

[4] The fact that the Lord in respect of His Divine Human is meant by 'the God of Israel' and 'the Holy One of Israel' is also clear from His being called Redeemer, Saviour, and Maker: REDEEMER in Isaiah 47:4 (Jehovah Zebaoth is our Redeemer, the Holy One of Israel is His name), and also in Isaiah 41:14; 43:14; 48:17; 54:5; SAVIOUR in Isaiah 43:3 and MAKER in Isaiah 45:11. From this it is also evident that no one other than the Lord is meant in the Old Testament Word by Jehovah, since He is called JEHOVAH GOD and THE HOLY ONE OF ISRAEL, REDEEMER, SAVIOUR, and MAKER. He is called Jehovah the Redeemer and Saviour in Isaiah,

That all flesh may know that I Jehovah am your Saviour, and your Redeemer, the Mighty One of Jacob. Isaiah 49:26.

In the same prophet,

That you may know that I Jehovah am your Saviour, and your Redeemer, the Powerful One of Jacob. ¹ Isaiah 60:16.

Also in Isaiah 43:14; 44:6, 24; 54:8; 63:16; Psalms 19:14.

[5] The fact that the Lord saved Israel, that is, those who belonged to the spiritual Church, may be seen in Isaiah,

I will tell of the mercies of Jehovah, the praises of Jehovah, according to all that Jehovah has rewarded us with - great [as He is] in goodness to the house of Israel. He said, Surely they are My people, children who do not lie. And therefore He became their Saviour. In all their affliction He suffered affliction, and the angel of His face delivered them; because of His love and His compassion He redeemed them, and took them and carried them all the days of eternity. Isaiah 63:7-9.
