What happens when the Priest isn't just doubting God—but trying to cast Him out?

In El Exorcismo de Dios , the prayer is reversed. The human looks at the sky and asks: "If You are the source of my pain... leave."

The film asks a brutal question: Can you be a vessel for the divine if you are convinced the divine hates you?

Unless... the "God" in question isn't the Creator, but an idol .
