At Ettal, Bonhoeffer experienced firsthand the gracious hospitality of the Benedictine life in which every guest is treated like Christ. He took meals with the brothers in the refectory, he was given access to the monastic library where he worked on his book Ethics, and he walked and skied on the snow-covered hills. In the company of his friend Eberhard Bethge, who came from Berlin for a long visit, he sang and made music. He bought Christmas presents for his family and friends back home, including the wife of Martin Niemöller, a fellow Confessing Church pastor being held in a concentration camp. He spent time with local school children, including his nephew, whom he personally nursed during a bout with influenza. In the midst of all this, he made ready for yet another season of Advent.
Bonhoeffer loved Advent and saw in this holy season of waiting and hope a metaphor for the entire Christian life. During the Advent of 1942, Bonhoeffer wrote a circular letter to some of his friends and former students:
The joy of God goes through the poverty of the manger and the agony of the cross; that is why it is invincible, irrefutable. It does not deny the anguish, when it is there, but finds God in the midst of it, in fact precisely there; it does not deny grave sin but finds forgiveness precisely in this way; it looks death straight in the eye but finds life precisely within it.
Following his arrest, Bonhoeffer would find a good analogy for Advent in the confinement and waiting all prisoners know. Advent reminds us, he wrote, that
Misery, sorrow, poverty, loneliness, helplessness, and guilt mean something different in the eyes of God than according to human judgment; that God turns toward the very places from which humans turn away; that Christ was born in a stable because there was no room for him in the inn—a prisoner grasps this better than others. And for them, this is truly good news.
The monastery was not a prison.
