One cannot therefore say that between the dying and the rising again there is no room left for a special condition of being dead. The logion of the Sign of Jonah places precisely this condition at the center. ~ Hans Urs von Balthasar, Mysterium Paschale
The logion is Mt 12.40: “As Jonah was three days and three nights in the belly of the whale, so will the Son of man be three days and three nights in the heart of the earth.” As I recall, for von Balthasar, revelation ceases on Holy Saturday, for the Word of God is dead and no longer speaking.
