Theosophia traces the long-hidden esoteric stream of Christian gnostic theosophy, revealing a "chivalric" religion of the Holy Spirit at the heart of Christianity. It shows that all three major branches of Christianity bear within them interrelated esoteric traditions. A deeply affirmative book, Theosophia introduces wholly unexpected aspects of Christian tradition. Where mainstream Christianity seems "anti-nature," Christian theosophy affirms a profound nature-mysticism; where it seems anti-erotic, theosophy affirms a powerful religious eroticism; and where it is portrayed as rigidly patriarchal, theosophy affirms a mysticism founded in the divine Sophia, the feminine personification of wisdom. Theosophia reveals hidden dimensions of our spiritual heritage that speak directly to our current social, ecological, and religious crises.
