Hans Urs von Balthasar calls this "one of her most central works". She discusses the moral and practical aspects of the sacrament in great depth. Some of the many areas covered include conversion, scruples, contrition, spiritual direction, laxity, frequency of confession, the confessions of religious and lay people, even the confessions of saints. One of the most complete spiritual treatises ever written on confession.
Adrienne von Speyr (1902–1967) was a Swiss medical doctor, a convert to Catholicism, a mystic, and an author of more than sixty books on spirituality and theology. She collaborated closely with theologian Hans Urs von Balthasar, her confessor for twenty-seven years, and together they founded the Community of Saint John. Her numerous books, published by Ignatius Press, are a major contribution to the wisdom of the Church. Among her most important works are Book of All Saints, Confession, The World of Prayer, Handmaid of the Lord, and The Passion from Within.
