“The resurrection cannot be tamed or tethered by any utilitarian test. It is a vast watershed in history, or it is nothing. It cannot be tested for truth; it is the test of lesser truths. No light can be thrown on it; its own light blinds the investigator. It does not compel belief; it resists it. But once accepted as fact, it tells more about the universe, about history, and about man's state and fate that all the mountains of other facts in the human accumulation.”
