Friedrich Nietzsche's The Gay Science: "Parable of the Madman"

Read this passage from Nietzsche's book The Gay Science. As you read, pay special attention to how Nietzsche uses the phrase "God is dead" and what this statement refers to specifically. Pay attention to the ways in which Nietzsche's remark about the death of God is not a theological statement - that is, it is not about religion. How exactly is Nietzsche's pronouncement that God is dead not a religious statement? How is Nietzsche's proclamation that "we have killed [God]" a condemnation of religion, and particularly a critique of those Western values passed down from Christianity? In other words, is God really dead, or are the values and commitments we derived from God's existence dead?
