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.

122. The twelve disciples of the Lord represented the church as to all things of faith and charity in the complex, as did also the twelve tribes of Israel (n. 2129, 3354, 3488, 3858, 6397). Peter, James, and John represented faith, charity, and the goods of charity in their order (n. 3750). Peter represented faith (n. 4738, 6000, 6073, 6344, 10087, 10580). And John represented the goods of charity, see the preface to the eighteenth (Arcana Coelestia 2135) and twenty-second Arcana Coelestia 2760vvv1-2 chapters of Genesis.

That there would be no faith in the Lord, because no charity, in the last time of the church, was represented by Peter's thrice denying the Lord before the cock crew the third ¹ time; for Peter there, in a representative sense, is faith; (n. 6000, 6073). "Cock crowing," as well as "twilight," signifies in the Word the last time of the church (n. 10134[1-13]). And "three" or "thrice," signifies what is complete to the end (n. 2788, 4495, 5159, 9198, 10127). The like is signified by the Lord's saying to Peter, when Peter saw John follow the Lord:

What is it to thee, Peter? follow thou Me, John; for Peter had said of John, What is this? (John 21:21, 22); (n. 10087).

John lay on the breast of the Lord, because he represented the good of charity (n. 3934, 10081). That the good of charity constitutes the church, is also signified by the words of the Lord from the cross to John:

Jesus saw His mother, and the disciple whom He loved, who stood by, and He said to His mother, Woman, behold thy son: and He said to that disciple, Behold thy mother; and from that hour that disciple took her to himself (John 19:26, 27).

"John" signifies the good of charity, and "woman" and "mother," the church; and the whole passage signifies that the church will be where the good of charity is; that "woman" in the Word means the church (see n. 252-253, 749, 770, 3160, 6014, 7337, 8994). And likewise "mother" (n. 289, 2691, 2717, 3703, 4257, 5580, 8897, 10490). All the names of persons and places in the Word signify things abstractly from them (n. 768, 1888,4310, 4442, 10329).

4731. 'And Reuben heard it' means the Church's confession of faith in general. This is clear from the representation of 'Reuben' as faith in the understanding, or doctrine, which is the first stage of regeneration - the truth of doctrine in its entirety by means of which one is able to arrive at the good of life, dealt with in 3861, 3866, here therefore the Church's confession of faith in general. The reason for Reuben's intervention here is that the Church which begins with faith would cease to be a Church if this Divine truth did not remain within it, namely the truth that the Lord's Human is Divine, this being the highest or inmost truth of the Church. This is the reason for Reuben's wishing to rescue Joseph, who represents that truth here, from the hands of his brothers to return him to his father - actions meaning that he wished to claim that truth for the Church. And further on, when Reuben went back to the pit and saw no Joseph there, it is said that he rent his clothes and said to his brothers, 'The lad is no more; and I, where do I go?' verses 29-30, meaning that no faith in the Lord existed any longer and so no Church.

[2] This supreme or inmost truth that the Lord's Human is Divine is denied by those within the Church who adhere to faith alone. Nevertheless because they know from the Word that there is a Divine side to the Lord and yet they do not grasp how the Human can be Divine, they therefore say He is both, by making a distinction between His Divine nature and His Human nature. But those who lead the life of faith - that is, those who have charity - worship the Lord as their God and Saviour; and while engaged in worship they think of the Lord's Divine without separating it from His Human. In so doing they acknowledge in their hearts everything in the Lord to be Divine. But because, when thinking from doctrine, they cannot grasp how the Human can be Divine, they speak purely from what doctrine teaches.
