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.

1799. 'Behold, a son of my house is my heir' means that in the Lord's kingdom there would be only that which is external. This is clear from the meaning in the internal sense of 'an heir' and of 'inheriting'. 'Becoming an heir' or inheriting means eternal life in the Lord's kingdom. All who are in the Lord's kingdom are heirs, for the source of the life in them is the Lord's life, which is the life of mutual love, and for that reason they are called 'sons'. The Lord's sons or heirs consist of all who have His life in them, for it is from Him that their life comes, and it is from Him that they have been born, that is, regenerated. Those born of another are that other's heirs; and so it is with all who are being regenerated by the Lord, for in that case they are receiving the life that is the Lord's.

[2] In the Lord's kingdom there are those who are external, those who are more interior, and those who are internal. Good spirits who dwell in the first heaven are external, angelic spirits who dwell in the second heaven are more interior, and angels who dwell in the third heaven are internal. Those who are external are not as close to or near the Lord as those who are more interior, and these in turn are not so close or near as those who are internal. Out of Divine love, or mercy, the Lord wills to have everyone near to Himself, so that they do not stand outside, that is, in the first heaven. His will is that they should dwell in the third heaven, and if possible not merely with Him but abiding in Him. Such is the nature of Divine or the Lord's love. But since at that time none but external things existed with the Church, He complained of this in the words that occur here - 'Behold, a son of my house is my heir' - by which is meant that in His kingdom there would thus be only that which is external. But comfort followed, and a promise of internal things, as described in the verses that follow next. What the external aspect of the Church is has been stated already in 1083, 1098, 1100, 1151, 1153.

[3] By itself doctrine does not constitute the external aspect of the Church, still less the internal, as stated above. Nor on the Lord's part is it its teachings that make one Church distinct and separate from another, but its life in accordance with those teachings, all of which, as long as they present what is true, regard charity as their basic principle. What else does doctrine do but teach men the kind of people they ought to be?

[4] In the Christian world it is their doctrines that cause Churches to be distinct and separate, and because of these they call themselves Roman Catholics, Lutherans, Calvinists or the Reformed, and Evangelicals, among other names. It is solely by reason of their doctrines that they are called by these names. This situation would never exist if they were to make love to the Lord and charity towards the neighbour the chief thing of faith. In this case their doctrinal differences would be no more than shades of opinion concerning the mysteries of faith which truly Christian people would leave to individual conscience, and in their hearts would say that a person is truly a Christian when he lives as a Christian, that is, as the Lord teaches. If this were so all the different Churches would become one, and all the disagreements which stem from doctrine alone would disappear. Indeed the hatred one man holds against another would be dispelled in an instant, and the Lord's kingdom on earth would come.

[5] The Ancient Church which existed immediately after the Flood, though scattered among many kingdoms, was of this nature. That is to say, people differed much from one another in matters of doctrine, but for all that, they made charity the chief thing. Also they regarded worship, not from the standpoint of doctrinal teachings which are matters of faith, but from that of charity which is a matter of life. This is what is meant by 'they all had one lip and their words were one', Genesis 11:1, regarding which see 1285.

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.
