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.

205. He that hath the key of David. That this signifies who has power by means of Divine truth is evident from the signification of key, as being the power of opening and shutting, in this case heaven and hell; for it follows, he that openeth and no man shutteth, and shutteth and no one openeth. Hence by key is here meant the power of saving (as may be seen above, n. 86), because to open heaven, and to shut hell, is to save; also from the representation of David, as being the Lord as to Divine truth. The reason why by David in the Word is meant the Lord, is, that in the Word the Lord is represented as to Divine truth by kings, and by priests as to Divine good, and especially by king David, because he had much care respecting the things of the church, and also wrote the Psalms. (That by kings in the Word is signified Divine truth, and by priests Divine good, may be seen above, n. 31. And, moreover, that by all names of persons and places in the Word spiritual things are signified, which are things pertaining to the church and to heaven, see above, n. 19, 50, 102.) The reason why it is said, he that hath the key of David is, because by David, as just said, is represented the Lord as to Divine truth; and the Lord has all power in the heavens and on earth from Divine good by means of Divine truth; for, in general, good has no power without truth, neither has truth any power without good, for good acts by means of truth. This is why Divine good and Divine truth proceed unitedly from the Lord, and in proportion as they are thus received by the angels, in the same proportion have the angels power: this, therefore, is the reason why the key of David is mentioned. (That all power pertains to truth from good may be seen in the work, Heaven and Hell 228-233, where the power of the angels of heaven is treated of; and also n. 539, in the same work.)

[2] That by David in the Word is meant the Lord is clearly evident from several passages where he is named in the prophets; as in Ezekiel:

"They shall be to me for a people, and I will be to them for a God, and my servant David king over them, that they may all have one shepherd. They shall dwell upon the earth, they and their sons, and the sons of their sons even to eternity; and David my servant shall be a prince to them to eternity" (37:23-25).

Again, in Hosea:

"The sons of Israel shall return and shall seek Jehovah their God, and David their king; and with fear shall they come to Jehovah and to his goodness in the end of days" (3:5).

It is said, "they shall seek Jehovah their God, and David their king," because by Jehovah in the Word is meant the Lord as to Divine good, which is the Divine as Being (esse), and by David a king, the Lord as to Divine truth, which is the Divine Manifestation (existere). (That by Jehovah in the Word is meant the Lord as to Divine good, may be seen in Arcana Coelestia 732, 2586, 2807, 2822, 3921, 4253, 4402, 7010, 9167, 9315.)

[3] In Zechariah:

"Jehovah shall preserve the tents of Judah first, that the glory of the house of David and the glory of the inhabitant of Jerusalem may not extol itself above Judah. In that day shall Jehovah protect the inhabitant of Jerusalem; and the house of David shall be as God, as the angel of Jehovah before them. And I will pour upon the house of David, and upon the inhabitant of Jerusalem, the spirit of grace. In that day there shall be a fountain open to the house of David, and to the inhabitants of Jerusalem" (12:7, 8, 10; 13:1).

The coming of the Lord is here treated of, and the salvation of those who belong to His spiritual kingdom. By the tents of Judah is meant the celestial kingdom; and by the house of David and the inhabitant of Jerusalem, the spiritual kingdom. The spiritual kingdom is formed of those in heaven and on earth who are in Divine truth, and the celestial kingdom of those who are in Divine good (as may be seen just above).

From these considerations it is plain that these words mean that those two kingdoms should act as one, nor should one exalt itself above the other (concerning these two kingdoms, see what is said in the work, Heaven and Hell 20-28). That by Judah is signified the Lord as to celestial love, and the celestial kingdom of the Lord, may be seen above (n. 119). And that by Jerusalem is signified the spiritual kingdom of the Lord, see Arcana Coelestia 402, 3654, 9166). The same is therefore signified by the house of David; therefore it is there said, "the house of David shall be as God, and as the angel of Jehovah;" by God also is meant the Lord as to Divine truth (see n. 2586, 2769, 2807, 2822, 3921, 4287, 4402, 7010, 9167); similarly by the angel of Jehovah (see above, n. 130, 200). David and his house have also a similar signification in the following passages.

[4] In Isaiah:

"Incline your ear, and come unto me; hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David. Behold I have given him for a witness to the peoples, a prince and a legislator to the nations" (55:3, 4).

These things are said concerning the Lord, who is here signified by David. In David:

"In the heavens thou shalt confirm thy truth: I have made a covenant with my chosen; I have sworn to David my servant, Even to eternity will I establish thy seed, and I will build up thy throne to generation and generation; and the heavens shall confess thy wonder, O Jehovah, and thy truth in the congregation of the holy ones" (Psalms 89:2-5).

These things also are spoken of the Lord, and not of David; for it is said, "I have sworn to David my servant, even to eternity will I establish thy seed, and build up thy throne to generation and generation"; which is not applicable to David, whose seed and throne are not established to eternity, and yet Jehovah sware; and an oath from Jehovah is irrevocable confirmation by the Divine (see Arcana Coelestia 2842). By the seed of David, in the spiritual sense, are meant those who are in truths from good from the Lord, and, in an abstract sense, truths themselves which are from good (as may be seen, Arcana Coelestia, 3373, 3380, 10249, 10445), and by throne is meant the spiritual kingdom of the Lord (n. 5313, 6397, 8625). The reason why David is here called a servant, as also above in Ezekiel is, that the term servant is used in the Word of all persons and things that serve and minister (see Arcana Coelestia 3441, 7143, 8241), and the Divine truth proceeding serves and ministers to the Divine good from which it proceeds. That it is the Lord as to Divine truth, or that it is Divine truth proceeding from the Lord, which is meant by David, is clear; for it is said, "in the heavens thou shalt confirm thy truth, and the heavens shall confess thy wonder, thy truth in the congregation of the holy ones." That they are also called holy who are in Divine truths, may be seen just above.

[5] Again:

"I will not profane my covenant; and what is pronounced by my lips will I not change. Once have I sworn by my holiness that I will not lie unto David. His seed shall be to eternity, and his throne as the sun before me, as the moon to eternity, as a faithful witness in the clouds" (Psalms 89:34-37).

That these things are said of the Lord, is evident from the whole of the psalm; for His coming is there treated of, and afterwards the rejection of Him by the Jewish nation. That the Lord is there treated of, and that He is meant by David, is evident from these words in the same Psalm:

"I have found David my servant; with the oil of my holiness have I anointed him. I will set his hand also in the sea, and his right hand in the rivers. He shall call me, Thou art my Father, my God, and the rock of my salvation. I also will make him my first-born, higher than the kings of the earth. I will set his throne as the days of the heavens" (vers. 20, 25-27, 29).

By David, by anointed, and by king, as in other passages of the Psalms, the Lord is meant. This may be seen clearly by those who understand the Word spiritually, but obscurely by those who understand it only naturally. The same is clear in the same:

"Thy priests shall be clothed with justice, and thy saints shall sing for joy; for thy servant David's sake turn not away the face of thine anointed; there will I make the horn of David to bud: I will ordain a lamp for mine anointed, upon himself shall his crown flourish" (Psalm 132:9, 10, 17, 18).

Here also the Lord is meant by David and by anointed; for He is treated of in this Psalm; as is plain from what goes before, where it is said:

"He sware unto Jehovah, I will not give sleep to mine eyes until I find out a place for Jehovah, habitations for the mighty One of Jacob; lo, we have heard of it at Ephratah" (Bethlehem). "We will go into his habitations, we will worship at his footstool" (ver. 2, 4-7).

[6] In order that David might represent the Lord as to Divine truth, the Lord willed to be born of the house of David, and also to be called the son of Jesse; but when He put off the Human from the mother, and put on that from the Father, which is the Divine Human, He was then no longer David's son. This is meant by the words of the Lord to the Pharisees: Jesus said to the Pharisees,

"What think ye of the Christ? whose Son is he? They said unto him, David's. He saith unto them, How then doth David by the spirit call him Lord, saying, The Lord said unto my Lord, Sit thou on my right hand till I make thine enemies thy footsool? If David then call him Lord, how is he his son?" (Matthew 22:42-45; Luke 20:41-44).

That the Lord glorified His Human, that is, put off the human from the mother, and put on the Human from the Father, which is the Divine Human, may be seen in The Doctrine of the New Jerusalem 293-295, 298-310.) Hence it is that He was not the son of David, just as He was not the son of Mary, whom therefore He did not call His mother, but "woman" as may be seen, Matthew 12:46-49; Mark 3:31 to the end; Luke 8:19-21; John 2:4, 19:25, 26. That the same is meant by the keys given to Peter as by the key of David - that the Lord has all power, and that He has this power by means of His Divine truth, will be seen in the article which now follows.
