“You can complicate the structure, but you see in this simple example how a certain belief can function objectively without anyone in the first person believing in it,” he explained.
Similarly, religion itself functions as an illusion, he continued. “We know it’s an illusion, but it fully functions as an illusion,” he said. “What happens in Christianity, in the moment of the cross,
God himself dies on the cross.”
Zizek, a proudly proclaimed atheist, said that his favorite theological text, the Book of Job, is also his favorite repudiation of God’s omniscience.
In the passage, Job asks God to explain the extreme suffering in his life. God responds that Job couldn’t possibly understand the actions of the creator of the universe.
“Usually this passage is read as the assertion of the arrogance of God,” Zizek said. But Zizek said his preferred reading of the passage holds that the world has become so complex that God does not understand its full scope.
