To understand this more exactly you only need to call before your soul what is contained in the book The Spiritual Guidance of Man and Humanity. There you will learn how the foundation of the Christ idea can be traced back to the mysteries of the spiritual worlds. In the book is shown the path followed in the spiritual worlds by the Being Who underlies the Christ idea before He revealed Himself in physical human incarnation at a certain point in earthly evolution. In coming to grips with these concepts concerning the spiritual guidance of mankind it is possible to sense what connection, or even lack of connection, there exists between anthroposophical spiritual science and ancient Gnosis. To describe the path of Christ through the spiritual worlds in the way it is done in The Spiritual Guidance of Man and Humanity would not yet have been possible for ancient Gnosis. But this ancient Gnosis also had its own image of Christ, its Christ idea. It was capable of drawing sufficient understanding out of its atavistic or clairvoyant knowledge to comprehend the Christ in a spiritual way, saying: In the spiritual world there is an evolution; the hierarchies—or, as Gnosis put it, the aeons—follow one another; and one such aeon is the Christ. Gnosis showed how, as aeon after aeon evolved, Christ gradually descended and revealed Himself in a human being. This can be shown even more clearly today, and you may read about it in the book The Spiritual Guidance of Man and Humanity.
