All that pertains to Them [Manifestations of God] —all Their states and conditions, all that They do, found, teach, interpret, illustrate, and instruct—is of a mystical and spiritual character and does not belong to the realm of materiality.

Such is the case of Christ’s coming from heaven. It has been explicitly stated in numerous passages of the Gospel that the Son of man came down from heaven, or is in heaven, or will go up to heaven. Thus in John 6:38 it is said: “For I came down from heaven”, and in John 6:42 it is recorded: “And they said, Is not this Jesus, the son of Joseph, whose father and mother we know? how is it then that he saith, I came down from heaven?”, and in John 3:13 it is stated: “And no man hath ascended up to heaven, but He that came down from heaven, even the Son of man which is in heaven.”
Consider how it is said that the Son of man is in heaven, even though at that time Christ was dwelling upon the earth.

Consider likewise that it explicitly says that Christ came from heaven, although He came from the womb of Mary and His body was born of her. It is therefore clear that the assertion that the Son of man came down from heaven has a mystical rather than a literal meaning, and is a spiritual rather than a material event. The meaning is that though in appearance Christ was born of the womb of Mary, yet in reality He came from heaven, the seat of the Sun of Truth that shines in the divine realm of the supernal Kingdom.
