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.

120. FROM THE ARCANA COELESTIA.

They who do not know that all things in the universe have relation to truth and good, and to the conjunction of both, that anything may be produced, do not know that all things of the church have relation to faith and love, and to the conjunction of both, that the church may be with man (n. 7752-7762, 9186, 9224). All things in the universe, which are according to Divine order have relation to good and truth, and to their conjunction (n. 2452, 3166, 4390, 4409, 5232, 7256, 10122, 10555). Truths are of faith and goods are of love (n. 4352, 4997, 7178, 10367). This is the reason that good and truth have been treated of in this doctrine; wherefore from what has been adduced, it may be concluded respecting faith and love; and it may be known what their quality is when they are conjoined, and what it is when they are not conjoined, by putting love in the place of good, and faith in the place of truth, and making applications accordingly.

They who do not know that each and all things in man have relation to the understanding and will, and to the conjunction of both, in order that man may be man, do not know clearly that all things of the church have relation to faith and love, and to the conjunction of both, in order that the church may be with man (n. 2231, 7752-7754, 9224, 9995, 10122). Man has two faculties, one of which is called the understanding and the other the will (n. 641, 803, 3623, 3539). The understanding is designed for receiving truths, thus the things of faith; and the will for receiving goods, thus the things of love (n. 9300, 9930, 10064). This is the reason why the will and the understanding have been also treated of in this doctrine; for from what has been adduced, conclusions may be drawn respecting faith and love, and it may be known what their quality is when they are conjoined, and what it is when they are not conjoined, by thinking of love in the will, and faith in the understanding.

They who do not know that man has an internal and an external, or an internal and an external man, and that all things of heaven have relation to the internal man, and all things of the world to the external, and that their conjunction is like the conjunction of the spiritual world and the natural world, do not know what spiritual faith and spiritual love are (n. 4392, 5132, 8610). There is an internal and an external man, and the internal is the spiritual man, and the external the natural (n. 978, 1015, 4459, 6309, 9701-9709). Faith is so far spiritual, thus so far faith, as it is in the internal man; and love likewise (n. 1594, 3987, 8443). And so far as the truths which are of faith are loved, so far they become spiritual (n. 1594, 3987). This is the reason why the internal and the external man have been treated of, for from what has been adduced, conclusions may be drawn respecting faith and love, what their quality is when they are spiritual, and what when they are not spiritual; consequently how far they are of the church, and how far they are not of the church.

3459. 'And swore, a man to his brother' means confirmation with those who do the good of truth. This is clear from the meaning of 'swearing' or of 'an oath' as confirmation, dealt with in 2842, 3037, 3375, and from the meaning of 'a man to his brother' as the good of truth, or what amounts to the same, one who is governed by that truth - 'man' meaning truth, see 265, 749, 1007, 3134, 3309, and 'brother' good, 2360. For what the good of truth is, see 3295, 3332. This good occurs with those represented here by Abimelech or by the Philistines, of whom Abimelech was the king, that is to say, those who make faith the essential thing of the Church and rank it above charity. No other good exists with such persons than the good of truth. Indeed they extract and draw out of the Word nothing else than references to faith and so to truth. They hardly notice references to good and so to life, and as a consequence they become more firmly convinced by matters of doctrine concerning faith and not by any concerning charity. When they do perform a good action it is one prescribed by matters of doctrine concerning faith. Good prescribed by these is called the good of truth.

[2] The Lord does indeed join Himself to those with whom this good exists, but not in the same way as He does to those who do the good of charity, for love and charity constitute spiritual conjunction, but not so faith except through love and charity. It is for this reason that the words used are not 'they made a covenant with Isaac' but 'they swore, a man to his brother'; for 'a covenant' has reference to good, which is the good of love and charity, whereas 'an oath' has reference to truth, which is the truth of faith, 3375. Also 'dwelling together' meant by 'a feast', 3456, is used in reference to those who do the good of truth. From people such as these in the next life I have been given to know that they have been separated from those who do the good of charity; for the latter are joined more nearly to the Lord than the former, since the former's good is so to speak hard and inflexible, and not communicable, and so is not in heaven but on the threshold of heaven.
