In New Christian thought, “charity” has a significantly different meaning than in the common modern English definition. In Swedenborg's works "charity" is usually the English rendering of the Latin word "caritas", which is also the root of the verb “to care.” If we think of “charity” as “a state of caring,” we can start seeing what Swedenborg was trying to convey.

“Caring” does not necessarily have to be emotional. You can take care of someone you don’t like, you can take care of business or errands or duties that have little or no emotional content. Swedenborg would call these “acts of charity,” things done from a desire to be a good person. But the idea of “caring” can elevate, too: When you care about someone it involves real affection, and to care about an idea or mission implies a deep commitment - it is a feeling, an emotional state. The ultimate state of “caring,” of course, would be caring about all of humanity, wanting what’s best for everyone on the planet. This is what Swedenborg would call “true charity,” and it is marked by love - the love of others. Importantly, though, it can't be left as an abstraction; it needs to be grounded out in action.

Or as Swedenborg puts it in Arcana Coelestia 8033: “Charity is an inward affection consisting in a desire which springs from a person's heart to do good to the neighbour, which is the delight of his life.”

At all these levels, though, charity cannot act on its own. It needs tools.

Imagine, for instance, a young mother falling and breaking her leg. Her four-year-old might love her desperately, but cannot take care of her. A paramedic, meanwhile, might see her as just a case number, but will get her stabilized and delivered to a hospital. The difference, obviously, is knowledge. The paramedic has a bunch of tested, true ideas in her head that give her the capacity to care for the mother; the four-year-old does not.

That knowledge is actually part of what Swedenborg would call “faith,” though he’s referring to spiritual things rather than medical ones. In general, “faith” in Swedenborg’s works refers to not just belief in the Lord but also the things we accept as true because they come to us from the Lord and the Lord’s teachings. If we take them and apply them to life, we can do works of charity - we can use knowledge to take care of people and things, to actually do something good. For this reason, faith and charity are often linked in Swedenborgian theology.

And just like the idea of caring, these items of faith can elevate. “Thou shalt not murder” is a good low-level matter of faith, and should certainly be applied if we want to be charitable people. “Love thy neighbor as thyself” is a bit higher, a bit more internal, and will help us be charitable on a deeper level. The idea that by loving others we are loving the Lord will take us to a deeper place yet.

And perhaps most beautiful of all is what happens when we reach a state of true charity. If we work to be good because we want to serve the Lord, the Lord will eventually change our hearts, transforming us so that we delight in being good and delight in loving and helping others. At that stage the ideas of faith change from being the masters over our evil desires to being the servants of our good desires. From a loving desire to be good and serve others we will seek and use knowledge that lets us fulfill that mission.

1798. That 'Abram said, See, to me You have not given seed' means that there was no internal dimension of the Church, [which is love and faith,] is clear from the meaning of 'seed' as love and faith, dealt with already in 255, 256, 1025, and in what follows below from the meaning of 'an heir'. The fact that love and faith deriving from love constitute the internal dimension of the Church has been stated and shown frequently already. No other kind of faith that constitutes the internal dimension of the Church is meant than the faith which is a product of love or charity, that is, which originates in love or charity.

[2] In a general sense faith embraces everything that is taught by the Church; but doctrinal teachings separated from love or charity do not in any way constitute the internal dimension of the Church, for such teachings are no more than knowledge which is present in the memory and which also exists with the worst of people, even with those in hell. But doctrinal teachings which originate in charity, that is, which are a product of charity, do constitute the internal dimension of the Church, for this dimension is essentially its life. The life itself constitutes the internal aspect of all worship, and so too do all doctrinal teachings that flow from the life that belongs to charity. It is these teachings when they comprise faith that are meant here, and it is faith such as this that constitutes the internal dimension of the Church, as may become clear from the single consideration that anyone who is leading a charitable life has an awareness of all things of faith.

[3] Just examine, if you care to do so, any doctrinal teachings, so that you may see what they are and what they are like. Do they not all have regard to charity, and so to faith that derives from charity? Take simply the Ten Commandments, the first of which is that you should worship the Lord God. Anyone who possesses the life of love or charity worships the Lord God, for it is in this that the life within him consists. Another commandment says that you should keep the Sabbath. Anyone in whom the life of love, that is, in whom charity, is present keeps the Sabbath holy since nothing delights him more than worshipping the Lord and declaring His glory day by day. The commandment that you should not kill has regard entirely to charity. Anyone who loves his neighbour as himself shudders at doing him any injury whatever, and even more at killing him. Likewise with the commandment that you should not steal, for the person who possesses the life of charity would rather give from what is his own to his neighbour than take away anything from him. Equally the commandment that you should not commit adultery. A man in whom the life of charity is present is minded rather to protect his neighbour's wife lest anyone should do such great harm to her, and regards adultery as a crime committed against conscience, such as destroys conjugial love and the responsibilities that go with it. Coveting things that belong to the neighbour is also contrary to the mind of those in whom the life of charity is present, for the essence of charity is to will good to others from oneself and what is one's own, thus they in no way covet what belongs to another.

[4] These Commandments, included among the Ten, are more external matters of doctrine concerning faith, which are not simply retained as knowledge in the memory of him in whom charity and the life of charity are present, but are in his heart. They are also inscribed upon him because they are grounded in his charity and so in his very life, in addition to other things of a dogmatic nature that are inscribed upon him which in a similar way he knows from charity alone. For he lives in accordance with a conscience for that which is right. Anything right or true which he is unable to understand and examine in this fashion he nevertheless believes in simplicity - that is, in simplicity of heart - to be right or true because the Lord has so said. Nor is anything wrong with such belief, even if that which is believed is not in itself true, only an appearance of truth.

[5] People may believe for example that the Lord can be angry, punish, tempt, and the like. Also, they may believe that in the Holy Supper the bread and wine have some spiritual meaning, or that flesh and blood are present in some way or other which they are able to explain. But whether they express the one or the other of these views about the Holy Supper, it makes no difference provided that two things are characteristic of these persons: Few people in fact give the matter any thought at all, and if any do give it any thought it makes no difference which view is held provided, a) It is done from a simple heart because it is what they have been taught, and b) They are leading charitable lives. When they hear that the bread and wine mean in the internal sense the Lord's love towards the whole human race, and the things that go with that love, and man's reciprocated love to the Lord and towards the neighbour, they believe it instantly and rejoice that it really is so. This is never the case with those who possess doctrine yet lack charity. They dispute everything and condemn anyone who does not speak - though they say it is to believe - as they do. From these considerations it may become clear to anyone that love to the Lord and charity towards the neighbour constitute the internal dimension of the Church.

3857. 'And Rachel was barren' means that interior truths were not received. This is clear from the representation of 'Rachel' as the affection for interior truth, dealt with already, and from the meaning of 'barren' as not giving rise to doctrines, nor thus Churches. This statement expresses the opposite of what is said in reference to Leah, that is, that 'Jehovah opened her womb', meaning that the affection represented by her gave rise to the doctrines taught by the Churches. The reason interior truths were not received is that interior truths are such as go above the range of man's belief, that is to say, they do not fall into ideas he has and are not conditioned by the outward appearances or the illusions of the senses by which everyone allows himself to be led. He does not believe interior truths unless in some way they coincide with those appearances or illusions.

[2] For example, it is an interior truth that intervals of time and of space do not exist in the next life, but states instead. Man who is within time and space while he lives in the world forms all his ideas from these, so much so that he cannot have any thought without them, 3404. Consequently unless the states which exist in the next life were described by means of the intervals of time and space which man experiences, that is, by means of the kind of things that are moulded by time and space, he would perceive nothing and so believe nothing, and as a consequence would receive nothing. Doctrine would in that case be barren and no Church would arise from it.

[3] Take another example. Unless celestial and spiritual affections were described by means of such things as constitute worldly and bodily affections man would not perceive anything, for these are the affections he experiences, and it is from them that he is able to have notions about celestial and spiritual affections. Yet the two types of affections are as different from each other, or as far apart, as heaven from earth. Take for example the glory of heaven, that is, of the angels in heaven, 3839. Unless man modelled his idea of the glory of heaven on the idea of the glory which exists in the world he would not grasp it at all and so would not acknowledge it. The same applies to all other interior or heavenly things.

[4] For this reason the Lord has spoken in the Word in accordance with man's own ability to grasp things and with the appearances that go with that grasp of them. The literal sense of the Word is such, yet at the same time is of such a nature that it holds within it the internal sense which contains interior truths. This then explains why it is said in reference to Leah that 'Jehovah opened her womb', and that 'Rachel was barren'; for as has been stated, 'Leah' represents the affection for exterior truth, 'Rachel' the affection for interior truth. But because exterior truths are the first truths which a person learns, the Lord has provided that by means of them he can be introduced into interior truths. This provision is meant by the statement in Genesis 30:22 that God at last remembered Rachel, hearkened to her, and opened her womb.

[5] The truth of all this may be seen from the Churches which existed in ancient times, and from their doctrinal teachings, namely that their teachings were formed from external truths. With the Ancient Church which existed after the Flood their doctrinal teachings were for the most part external representatives and meaningful signs which had internal truths stored within them. For the majority of its members holy worship consisted in those external representatives and signs. If anyone had told them that the essential ingredients of Divine worship were not those representatives and meaningful signs but the spiritual and celestial realities represented and meant by these, they would have rejected them altogether, and so the Church would have ceased to exist. This applied even more to the Jewish Church. If anyone had told them that their religious observances received their holiness from the Divine things that were the Lord's within them they would not have acknowledged them at all.

[6] Such also was mankind when the Lord came into the world. They had grown even more bodily-minded, especially so those who were members of the Church. This is quite evident even from the disciples who, though with the Lord constantly and hearing so many things about His kingdom, were as yet unable to perceive interior truths. They were still unable to have any other concept of the Lord than such as exists with the Jews at the present day about the Messiah whom they are still awaiting. They imagined that He would promote that people to a position of dominion and glory over all nations throughout the world. And after hearing so many things from the Lord about the heavenly kingdom the disciples were still unable to think anything else than that the heavenly kingdom would be like an earthly kingdom, where God the Father would be supreme, after Him the Son, and then themselves the twelve, and so would reign in this order. For the same reasons also James and John asked to sit one on His right and the other on the left, Mark 10:35-37; and the rest of the disciples were angry at these two wishing to be greater than the rest, Mark 10:41; Matthew 20:24. For the same reason also, after teaching them what it was to be greatest in heaven, Matthew 20:25-28; Mark 10:42-45, the Lord still spoke in the way that they themselves thought. That is to say, He spoke of them sitting on twelve thrones and judging the twelve tribes of Israel, Luke 22:24, 30; Matthew 19:28.

[7] If they had been told that the word 'disciples' was not used to mean themselves but all people in whom the good of love and faith dwells, 3354, 3488, and also that in the Lord's kingdom there are no thrones, nor positions of government and dominion, as in the world, and that they would not be able to pass judgement on even the smallest aspect of any one person, 2129, 2553, they would have rejected that saying, and each would have left the Lord and gone back to his own employment. The reason why the Lord spoke in the way He did was so that they would receive those things and through them be introduced into internal truths. For within the external truths which the Lord spoke internal truths lay stored away which in course of time are laid bare. And when these are laid bare those external truths are dispelled and serve solely as the objects or the means for thought about internal ones. From these considerations one may recognize what is meant by the fact that Jehovah opened Leah's womb first and she bore sons to Jacob, and that Rachel did so subsequently.
