After living in the Cologne Carmel (1934-38), she was moved to the Carmelite monastery in Echt, Netherlands. In Echt, Edith Stein completed her study of "The Church's Teacher of Mysticism and the Father of the Carmelites, John of the Cross, on the Occasion of the 400th Anniversary of His Birth, 1542-1942." In 1941 she wrote to a friend, who was also a member of her order: "One can only gain a scientia crucis (knowledge of the cross) if one has thoroughly experienced the cross. I have been convinced of this from the first moment onwards and have said with all my heart: 'Ave, Crux, Spes unica' (I welcome you, Cross, our only hope)." Her study on St. John of the Cross is entitled: "Kreuzeswissenschaft" (The Science of the Cross).
When Edith Stein was beatified in Cologne on 1 May 1987, the Church honoured "a daughter of Israel", as Pope John Paul II put it, who, as a Catholic during Nazi persecution, remained faithful to the crucified Lord Jesus Christ and, as a Jew, to her people in loving faithfulness."
