Christians emphasize that in distinguishing an evil spirit from an angel, angels must glorify Jesus and teachings must be based on scripture. New Church adherents say that Swedenborg would agree, since he said no evil spirit can utter the name of Jesus; it signifies salvation, and those in the spiritual world speak as they think. Unlike many spiritualists, Swedenborg praises Jesus as the God of heaven and earth and his doctrines are derived from scriptural references. According to Swedenborg, none of the teachings originated from an angel or spirit and the spiritual world was revealed to him so humanity would know that there is life after death: "... When I think of what I am about to write and while I am writing, I enjoy a complete inspiration, for otherwise it would be my own; but now I know for certain that what I write is the living truth of God." "That the Lord manifested Himself before me His servant, and sent me to this office, and that He afterward opened the sight of my spirit, and so has admitted me into the spiritual world, and has granted to me to see the heavens and the hells, also to converse with angels and spirits, and this now continuously for many years, I testify in truth; likewise, that from the first day of that call I have not received any thing which pertains to the doctrines of that church from any angel, but from the Lord alone while I read the Word."
