In his short work The Doctrine of the Lord, Swedenborg presents an answer to the time-honored question of how Jesus and God are related: he argues that they became in every way one and the same. Throughout his works Swedenborg uses the term “Lord” to refer to Jesus as the embodiment of God. In this work he emphasizes that the traditional trinity of Father, Son, and Holy Spirit should be thought of not as three separate divine Persons that have always coexisted but as three aspects now present within one divine Person―Jesus in his resurrection.

The Lord also touches upon key themes in Swedenborg’s theology: the spiritual reasons why the Lord came to earth; the significance of the death and resurrection of his human form; and the ways in which his coming was foretold in the Old Testament. Throughout the book, Swedenborg provides extensive biblical references to support his arguments. He concludes with a brief chapter describing the New Jerusalem, a reference to both the city described in the book of Revelation and the new spiritual age that is now unfolding.
