“Had there been no cross, Christ could not have been crucified. Had there been no cross, life itself could not have been nailed to the tree. And if life had not been nailed to it, there would be no streams of immortality pouring from Christ’s side, blood and water for the world’s cleansing. The legal bond of our sin would not be cancelled, we should not have attained our freedom, we should not have enjoyed the fruit of the tree of life and the gates of paradise would not stand open. Had there been no cross, death would not have been trodden underfoot, nor hell despoiled.
— St. Andrew of Crete, Office of Readings for the Exaltation of the Holy Cross
