One of the unique facets of Swedenborg’s theology is his assertion that the Last Judgment as foretold in the book of Revelation has already happened—that it took place in the spiritual world and would have lasting effects on earth.This volume comprises two short works, originally published separately, which describe the Last Judgment as Swedenborg claims to have witnessed it over the course of many months in 1757. In Last Judgment, first published in 1758, Swedenborg lays out how and why the Last Judgment occurred, explaining that history can be divided into a series of spiritual ages or churches. At the end of each age, evil threatens to overwhelm both the physical and the spiritual worlds, and the Lord restores balance between good and evil with a “Last Judgment.” Thus the 1757 Last Judgment, Swedenborg says, applied only to the souls of people who had lived since the time of Christ, and the reformation of the spiritual world allowed humanity to enter the next age with a new understanding of religion. In the second half of Last Judgment, Swedenborg describes how various types of people were judged, a theme he continues in the 1763 short work Supplements.The new spiritual age that Swedenborg saw emerging during his lifetime is one of the foundational themes in his theology (a theme he explores more deeply in his later work, Revelation Unveiled, which is a commentary on the book of Revelation). In Supplements, Swedenborg succinctly introduces his understanding of the connection between heaven and earth and of how that connection plays out over the course of human history.
Emanuel Swedenborg (born Emanuel Swedberg; February 8, 1688–March 29, 1772) was a Swedish scientist, philosopher, Christian mystic, and theologian. Swedenborg had a prolific career as an inventor and scientist. At the age of fifty-six he entered into a spiritual phase in which he experienced dreams and visions. This culminated in a spiritual awakening, where he claimed he was appointed by the Lord to write a heavenly doctrine to reform Christianity. He claimed that the Lord had opened his eyes, so that from then on he could freely visit heaven and hell, and talk with angels, demons, and other spirits. For the remaining 28 years of his life, he wrote and published 18 theological works, of which the best known was Heaven and Hell (1758), and several unpublished theological works.
Swedenborg explicitly rejected the common explanation of the Trinity as a Trinity of Persons, which he said was not taught in the early Christian Church. Instead he explained in his theological writings how the Divine Trinity exists in One Person, in One God, the Lord Jesus Christ. Swedenborg also rejected the doctrine of salvation through faith alone, since he considered both faith and charity necessary for salvation, not one without the other. The purpose of faith, according to Swedenborg, is to lead a person to a life according to the truths of faith, which is charity.
Swedenborg's theological writings have elicited a range of responses. Toward the end of Swedenborg's life, small reading groups formed in England and Sweden to study the truth they saw in his teachings and several writers were influenced by him, including William Blake (though he ended up renouncing him), Elizabeth Barrett Browning, August Strindberg, Ralph Waldo Emerson, Charles Baudelaire, Balzac, William Butler Yeats, Sheridan Le Fanu, Jorge Luis Borges and Carl Jung. The theologian Henry James Sr. was also a follower of his teachings, as were Johnny Appleseed and Helen Keller.
In contrast, one of the most prominent Swedish authors of Swedenborg's day, Johan Henrik Kellgren, called Swedenborg "nothing but a fool". A heresy trial was initiated in Sweden in 1768 against Swedenborg's writings and two men who promoted these ideas.
In the two centuries since Swedenborg's death, various interpretations of Swedenborg's theology have been made (see: Swedenborgian Church), and he has also been scrutinized in biographies and psychological studies.
