Part of the Christian message is the concept of redemption. What does it mean, to say that the Lord redeemed people?

Here are the key concepts about redemption in New Christian thought, as excerpted from Swedenborg's works (written in the 1700s):

"Jehovah God came down and took upon Himself a human form, in order to redeem and save mankind.

Christian churches today believe that God the Creator of the universe fathered a Son from eternity, who came down and took upon Himself human form to redeem and save mankind. But this is an error and collapses of its own accord, so long as the mind concentrates on the oneness of God, and the reason looks upon as fiction or worse the idea that the one God fathered a Son from eternity, and also that God the Father together with the Son and the Holy Spirit, each of whom is severally God, is one God. This fiction is utterly exploded, like a meteorite in the atmosphere, when it is shown from the Word that it was Jehovah God Himself who came down and became man and also was the Redeemer." (True Christian Religion 82)

"In the process of taking on a human manifestation, God followed his own divine design.... Now, because God came down, and because he is the design..., there was no other way for him to become an actual human being than to be conceived, to be carried in the womb, to be born, to be brought up, and to acquire more and more knowledge so as to become intelligent and wise. Therefore in his human manifestation he was an infant like any infant, a child like any child, and so on with just one difference: he completed the process more quickly, more fully, and more perfectly than the rest of us do." (True Christian Religion 89)

"There is a belief that the Lord in his human manifestation not only was but still is the Son of Mary. This is a blunder, though, on the part of the Christian world. It is true that he was the Son of Mary; it is not true that he still is. As the Lord carried out the acts of redemption, he put off the human nature from his mother and put on a human nature from his Father. This is how it came about that the Lord's human nature is divine and that in him God is human and a human is God.' (True Christian Religion 102)

"Suffering on the cross was the final trial the Lord underwent as the greatest prophet. It was a means of glorifying his human nature, that is, of uniting that nature to his Father's divine nature. It was not redemption. There are two things for which the Lord came into the world and through which he saved people and angels: redemption, and the glorification of his human aspect. These two things are distinct from each other, but they become one in contributing to salvation.

In the preceding points we have shown what redemption was: battling the hells, gaining control over them, and then restructuring the heavens. Glorification, however, was the uniting of the Lord's human nature with the divine nature of his Father. This process occurred in successive stages and was completed by the suffering on the cross." (True Christian Religion 126)

"Redemption consisted in the conquest of the hells, the ordering of the heavens and the establishment of a new church, because without them no one could have been saved. This is their proper order: the hells had first to be conquered, before a new heaven of angels could be formed, and this had to be formed before a new church could be established on earth. For people in the world are so linked with the angels in heaven and the spirits in hell, that in the interiors of their minds they are identified with one party or the other." (True Christian Religion 115)

"Without that redemption no man could have been saved, nor could the angels have continued in a state of integrity. It shall be told first what redemption is. To redeem means to liberate from damnation, to deliver from eternal death, to rescue from hell, and to release from the hand of the devil the captive and the bound. This the Lord did by subjugating the hells and establishing a new heaven." (True Christian Religion 118)

103. To this I shall add a revelation, that the soul which comes from the father is the person himself, and the body which comes from the mother, is not in itself the person, but a product of the person. This is merely its covering, woven of substances from the natural world, while the soul is of substances from the spiritual world. After death every person lays aside the natural which he got from his mother, and keeps the spiritual which he had from his father, together with a sort of fringe (limbus) around it composed of the purest natural substances. In the case of those who come into heaven this fringe is below with the spiritual side uppermost; with those who come into hell, the fringe is uppermost and the spiritual side is below. That is why a human angel receives what he says from heaven, so that it is good and true, but a human devil receives what he says from hell when he speaks from the heart, as he does in private, but as if from heaven when he speaks with the lips only, as he does in public.

[2] Since a person's soul is his very self, and by its origin the soul is spiritual, it is clear why the father's mind, attitude, character, inclination and affection of love live on in one descendant after another, and show up from one generation to the next. That is why many families, even whole nations, are recognisable likenesses of their ancestor; there is a shared type which shows up in the faces of each of his descendants, and this is only changed by the spirituality of the church. The type shared by Jacob and Judah still lives on in their descendants, allowing them to be distinguished from others, because down to the present day they have kept strictly to their religion. For in the seed from which each individual is conceived there is a shoot or cutting of the father's soul in all its completeness, wrapped in a covering of natural elements. These control the formation of the body in the mother's womb, where it may take on a resemblance to the father or the mother, though the father's type remains in it and constantly strives to come out. So if it is unable to do so in the first generation, it achieves this in subsequent ones.

[3] The reason why the father's type in all its completeness is in the seed is that, as already said, the soul is in origin spiritual, and the spiritual has nothing in common with space, so it can be reproduced in a small compass just as well as on a large scale. As for the Lord, when He was in the world, He put off by redeeming acts all the human He had from His mother, and put on the Human from the Father, that is, the Divine Human. That is why it is that in Him man is God and God is man.
