When the Nazis invaded Poland in 1939, the Catholic Church had a powerful influence on the Polish people. Because this threatened their absolute control, the Nazis set out to destroy the clergy, who were arrested and thrown into concentration camps along with the Jews. Among them was a young seminarian, Kazimierz Majdanski. In "You Shall Be My Witnesses "Majdanski chronicles his prison experiences during the war. His words are a testament to the faith and courage of the many voices that were silenced in concentration camps."
