series for the Sammlung Klosterberg, translated French Resistance poetry, helped to produce plays (including a staging of his own translations of Bernanos' Dialogues of the Carmelites and Claudel's The Satin Slipper), published book-length studies on Maximus the Confessor and Saint Gregory of Nyssa, and regularly lectured to students. He established the Studentische Schulungsgemeinschaft in 1941, an institute for student formation that featured courses and conferences by Hugo Rahner, Martin Buber, Yves Congar, Gustav Siewerth, Henri de Lubac, and others. To the students, von Balthasar offered liturgies, sermons, retreats, and spiritual direction, with a particular emphasis on the Spiritual Exercises of Saint Ignatius of Loyola. According to Jacques Servais, "A good number of the young men eventually entered the Society of Jesus, while others decided to remain in the lay state, hoping to find a form of consecration to God in the world." Collaboration with Adrienne von Speyr During his first months in Basel, he met the physician Adrienne von Speyr through a mutual friend.

Shortly following her reception into the Catholic Church on 1 November 1940—at a liturgy celebrated by von Balthasar—von Speyr began reporting intense experiences in prayer, including visions of Christ's Passion and encounters with various saints. In von Balthasar's words, "A veritable cataract of mystical graces poured over Adrienne in a seemingly chaotic storm that whirled her in all directions at once." He began to accompany her as a spiritual director, in order to help evaluate the experiences. After he became convinced of the authenticity of von Speyr's mysticism, von Balthasar and von Speyr both began to believe that they had a shared theological mission. Between 1944 and 1960, von Speyr dictated to von Balthasar some 60 books of spiritual and Scriptural commentary. Given von Speyr's responsibilities as a mother and a practicing doctor, von Balthasar alone worked to arrange, edit, and publish the texts. In 1947, he founded
