Yeah, I'm with you. She starts by stating that Christians don't conflate nature and heaven and then proceeds to do just that. It's pretty close to gobbledygook.

My take on the Cosmic Christ is that all creation was initiated by God the Father through God the Son and, ultimately, points back toward God. In the words of the Nicene Creed, "Through him all things were made."

It's a bit more complex than that, but my point is that one doesn't have to go whole hog into pantheism, as this essay suggests, to accept the notion of the Cosmic Christ. It is consistent with traditional Christian creation spirituality.
