A first step in developing a theology of onions is to recognize how beautiful they are. When I watched the video above from the Spiritual Literacy DVD series, using the words of Mary Hays Grieco to help me find God in an onion, I saw this clearly. I, too, believe that we can experience the beauty of God in the beauty of the world, onions much included.
At the same time as I saw this video, I received a meal from Blue Apron meal delivery service that included onions to be used in a salad. I watched the videos on dicing onions (shared at bottom of post) and thought to myself: "Well that's interesting, but it's not exactly mystical or spiritual, you can't chop God up with a knife."
