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.

9434. 'And the sight of Jehovah's glory was like a devouring fire on the top of the mountain in the eyes of the children of Israel' means Divine Truth beaming brightly with the good of love in heaven itself, but harmful and ruinous with those restricted to its outward level, separated from the inward. This is clear from the meaning of 'the sight of Jehovah's glory' as the appearance presented by Divine Truth emanating from the Lord (the fact that 'the sight of' means the appearance presented before the eyes is self-evident; and for the meaning of 'Jehovah's glory' as Divine Truth emanating from the Lord, see 9429); from the meaning of 'fire' as love in both senses, dealt with in 4906, 5215, 6314, 6832, 7324, in this instance God's love itself; from the meaning of 'the top of the mountain' as the inmost part of heaven, for 'Mount Sinai' means heaven, 9420, 9427, and its highest point, which is called 'the top' and the peak, means its inmost part, 9422; from the meaning of 'devouring' as consuming, and so harming and ruining; and from the representation of 'the children of Israel' as those restricted to outward things, apart from inward ones, dealt with often above. From all this it becomes clear that 'the sight of Jehovah's glory was like a [devouring] fire on the top of the mountain' means Divine Truth beaming brightly with the good of love in heaven itself; and the statement that it was 'like a devouring fire in the eyes of the children of Israel' means that with those restricted to its outward level, apart from the inward, it was harmful and ruinous.

[2] The implications of all this are that there are two kinds of love which are complete opposites, heavenly love and hellish love. Heavenly love consists of love to the Lord and love towards the neighbour; hellish love consists of self-love and love of the world. Those with whom hellish loves reign are in hell, whereas those with whom heavenly loves reign are in heaven. For love is what constitutes the actual life within a person; without the love there is no life whatever. In everyone the heat and fire that his life possesses originate in his love; without that animating heat and fire he has no life, as is plainly evident. From this it follows that the character of the love determines the character of the life, and therefore that the character of the love determines that of the person. This being so, anyone can know from what his loves are whether he has heaven within himself or hell. The love present in a person is like a fire or flame, and in addition constitutes, as has been stated, the fire or flame of life; and the faith present there is like the light radiating from that fire or flame, and in addition constitutes the light which enlightens the more internal parts of his understanding. This also reveals the character of the light which gives rise to faith among those governed by heavenly love and the character of the light which gives rise to faith among those ruled by hellish love. The latter kind of light gives rise to faith that is no more than persuasion, which in itself is not faith at all, only a conviction that something is so, dictated by selfishness and worldliness, see 9363-9369. In the Church at the present day spiritual life, which is eternal life, is thought to lie in faith alone, thus in faith without the good works of heavenly love. But anyone who gives thought to the matter can see from the things which have now been stated what the character of that life is.

[3] Something must be said next about what Divine fire, that is, Divine Love, is like among those governed by heavenly love and what it is like among those ruled by hellish love. Among those governed by heavenly love it is God's fire or love constantly creating and renewing the interior parts of the will and enlightening the interior parts of the understanding. But among those ruled by hellish love it is God's fire or love constantly harming and ruining; and the reason for this is that among these people God's love meets with contrary feelings that destroy it. For it is turned into the fire or love of self and the world, and so into contempt for others in comparison with themselves, into feelings of enmity towards all who do not support them, thus into feelings of hatred, feelings of vengeance, and finally the readiness to behave brutally. This is why Jehovah's fire appeared before the eyes of the children of Israel as a devouring or consuming one. For being restricted to outward things, apart from inward, they were ruled by selfish and worldly love.

[4] The fact that this fire was to them a devouring and consuming one is again evident elsewhere in Moses,

It happened, when you heard the voice out of the midst of the darkness, and the mountain was burning with fire, that you came near to me, all the heads of your tribes and your elders. And you said, Lo, Jehovah our God has caused us to see His glory and His greatness, and we have heard His voice out of the midst of the fire. Why therefore should we die? For this great fire will devour us; if we hear the voice of Jehovah our God any more we shall certainly die. Deuteronomy 5:23-25.

See also what has been shown in 6832, 8814, 8819, and the places quoted in 9380 showing that the character of this people was such. There are other places in the Word in which 'devouring fire' is used in reference to the wicked and means ruination, for example in Joel,

The day of Jehovah is coming, a day of darkness and thick darkness, a day of cloud and gloom. Fire devours before them, ¹ and behind them a flame burns. The land before them is like the garden of Eden, but behind them a desolate wilderness. ² Joel 2:1-3.

[5] In Isaiah,

Jehovah will cause His glorious voice ³ to be heard, in the flame of a devouring fire. Isaiah 30:30.

In the same prophet,

Who among us will dwell with the devouring fire? Who among us will dwell with the hearths of eternity? Isaiah 33:14.

In the same prophet,

You will be punished ⁴ by Jehovah with the flame of a devouring fire. Isaiah 29:6.

In Ezekiel,

Your descendants will be devoured by fire. Ezekiel 23:25.

In these places 'a devouring fire' is the fire of desires that spring from self-love and love of the world, for this fire is that which consumes a person and ruins the Church. This was also represented by the fire that went out from before Jehovah, which devoured Aaron's sons Nadab and Abihu, because they put foreign ⁵ fire in their censers, Leviticus 10:1-2. 'Putting foreign fire in censers' means introducing worship that springs from a love other than that which is heavenly. Such fire means selfish and worldly love, and every desire arising from it, see 1297, 1861, 5071, 5215, 6314, 6832, 7324, 7575, 9141.
