When Zarathustra was alone he said to his heart: "Could it be possible! This old saint in the forest hath not yet heard of it, that God is dead!" [Thus spake Zarathustra, Friedrich Nietzsche]

To kill God is to become god oneself; it is to realize already on this earth the eternal life of which the Gospel speaks. [The myth of Sisyphus, Albert Camus]

The god that can be pointed out is an idol, and the religiosity that makes an outward show ia an imperfect form of religiosity [Concluding unscientific postscript, Soeren Kierkegaard]

The most dreadful sort of blasphemy is that of which "Christendom" is guilty: transforming the God of Spirit into ... ludicrous twaddle. And the stupidest divine worship, more stupid than anything that is or was to be found in paganism, more stupid than worshiping a stone, an ox, an insect, more stupid than all that is - to worship under the name of God ... a twaddler. [Soeren Kierkegaard]
