To help celebrate the fourth centenary of the birth of St. John of the Cross in 1542, Edith Stein received the task of preparing a study of his writings. She uses her skill as a philosopher to enter into an illuminating reflection on the difference between the two symbols of cross and night. Pointing out how entering the night is synonymous with carrying the cross, she provides a condensed presentation of John's thought on the active and passive nights, as discussed in The Ascent of Mount Carmeland The Dark Night.
