In The New Apocalypse, Thomas J. J. Altizer (perhaps the most radical theologian of our age and a major exponent of the death of God theology), advances the thesis that William Blake is the most original prophet and seer in the history of Christendom, that he created a whole new form of vision embodying a modern radical and spiritual expression of Christianity, and that an understanding of his revolutionary work demands a new form of theological understanding.
Thomas Jonathan Jackson Altizer was a radical theologian who is known for incorporating Friedrich Nietzsche's conception of the "death of God" and G. W. F. Hegel's dialectical philosophy into his systematic theology.
