This enlightened essay by French researcher Maurice Aniane is one of the most penetrating expositions of Western alchemy I have ever read. He is unrelenting in his intention to dishevel the truths of alchemy and deeply fulfilling in his erudite conclusions.  

    Aniane's essay grounds the Eucharistic tradition of medieval Christianity in alchemical philosophy and radiates the Eucharistic effusion into the heaviest leaden states of matter, transubstantiating not just the bread, wine, and spirit but the Stone, lead, and the human body.

     Alchemy in medieval Christianity aimed to transfigure terrestrial substances through sacrificing inanimate matter to reveal its inner essence which is the original divine spark of consciousness. That process revealed the divine light and presence manifest even in the heaviest of objects like lead. Christian alchemy also expressed the sacred nature of time as a stillness transmuted into “moments” of eternity—a beautiful idea you might have experienced as a child.

In return, alchemy gave medieval Christianity a technical application in the psycho-cosmic realm. From the viewpoint of medieval Christianity, alchemy was a powerful spiritual technology that originated in the mind of God.
