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.

450. XVI. Spurious charity, hypocritical charity and dead charity.

True charity which is alive is impossible except when it makes one with faith, and except when both jointly look to the Lord. For these three, the Lord, charity and faith, are the three essentials for salvation, and when they are one, charity is charity, faith is faith and the Lord is in them, and they are in the Lord (see above 363-372). However, where these three are not linked together, charity is either spurious or hypocritical or dead. From the time it was founded Christianity has been beset by various heresies, and these continue also at the present time; and in each one of these the three essentials - God, charity and faith - have been and are acknowledged, since in their absence there can be no religion, As regards charity specifically, it can be attached to any heretical belief, such as that of Socinians, Enthusiasts or Jews, even the belief of idolaters. And all these can believe that it is really charity, since it resembles that in outward form; but it actually changes its nature depending on the belief to which it is attached or linked. For a demonstration of this, see the chapter on faith.

612. 'Noah was a righteous and blameless man among members of his own generation' means that he was such as could be endowed with charity. This is clear from the meaning of 'righteous' and 'blameless', 'righteous' having regard to the good of charity, and 'blameless' to the truth of charity; also from the fact that the essential element of that Church was charity, in the Lord's Divine mercy to be dealt with later on. That 'righteous' has regard to the good of charity and 'blameless' to the truth of charity is clear from the Word, as in Isaiah,

They will seek Me daily, and will desire the knowledge of My ways, as a nation that does righteousness and does not forsake the judgement of their God. They will ask of Me the judgments of righteousness, they will desire the approach of God. Isaiah 58:2.

Here 'judgement' stands for things that have to do with truth, and 'righteousness' for those that have to do with good. 'Doing judgement and righteousness' became so to speak a stock phrase for truth and good, as in Isaiah 56:1; Jeremiah 22:3, 13, 15; 23:5; 33:15; Ezekiel 33:14, 16, 19. And the Lord said,

The righteous will shine like the sun in the kingdom of their Father. Matthew 13:43.

This stands for people who are endowed with charity. Also in reference to the close of the age the Lord said,

The angels will come out and separate the evil from the midst of the righteous. Matthew 13:49.

Here also it stands for people who receive the good that stems from charity.

[2] 'Blameless' however means the truth that stems from charity. For truth can come from one of many other origins, but that which stems from the good of charity deriving from the Lord is called 'blameless' and 'a blameless man', as in David,

Who will sojourn in Your tent? Who will dwell on Your holy mountain? He who walks blameless and does righteousness and speaks truth in his heart. Psalms 15:1-2.

This describes a person who is blameless. In the same author,

With the holy You behave in a holy way, and with a blameless man (vir). You show Yourself blameless. Psalms 18:15.

Here 'a blameless man' is one who is so by reason of what is holy, that is, good stemming from charity. In the same author,

Jehovah will withhold no good thing from those walking blamelessly. Psalms 84:11.

[3] A 'blameless' person is one who is true by reason of good, that is, one who speaks and does what is true from charity. This is clear from the fact that so many times the words 'walking', 'way', and also 'upright' or 'uprightness', words used in connection with truth, are applied to someone who is blameless or to blamelessness, as in David,

I will instruct the blameless in the way how far he shall come towards me. I will walk in the blamelessness of my heart within my house. Psalms 101:2.

And in verse 6 of the same Psalm,

He who walks in the way of the blameless will serve Me.

In the same author,

Blessed are the blameless in the way, walking in the law of Jehovah. Psalms 119:1.

In the same author,

Blamelessness and uprightness will protect me. Psalms 25:21.

In the same author,

Mark the blameless man, and behold the upright, for the latter end of that man is peace. Psalms 37:37.

From these quotations it is clear that someone who does what is good is called 'righteous', while someone who does truth deriving from it, which is the same as 'doing righteousness and judgement', is called 'blameless'. 'Holiness and righteousness' belongs on the celestial side of faith, 'blamelessness and judgement' on the derivative spiritual side.
