She once asked an archbishop whether it was acceptable for a nun to lie if doing so could save Jewish children from the Nazis. His answer was only six words: “Let’s lie, my daughter, let’s lie.” Those words gave Sister Denise Bergon the courage she needed. In 1942, at thirty years old, she was Mother Superior of Notre-Dame de Massip, a convent school in southwestern France. Jewish families were being torn apart. Some children escaped into the countryside, frightened and hungry. Sister Denise had already sheltered several, passing them off as ordinary Catholic students. She knew protecting more would mean misleading the authorities. She secretly wrote to Archbishop Jules-Géraud Saliège of Toulouse, who had openly condemned the persecution of Jews. He told her, “Let’s lie, my daughter, let’s lie.” Resistance couriers and desperate relatives began bringing Jewish children to the convent. Eventually eighty-three were hidden inside. Sister Denise shared the truth with only three trusted people. The other nuns were told the children were refugees. Many of the Jewish children did not know Catholic prayers. She claimed they came from strict communist families that had rejected religion. The story protected them. Whenever authorities arrived, the children hid in concealed cellars beneath the chapel floor. At night Sister Denise buried the money, jewelry and identity documents parents had entrusted to her. She kept a private record of the children’s real identities. For twenty months the operation continued. When the war ended all eighty-three children had survived. Whenever relatives came forward she helped reunite them and returned everything she had buried. For children whose parents had died she helped arrange safe homes. She returned to her quiet religious life and never wrote a memoir. The children never forgot her. As adults they returned with their own children and grandchildren. Sister Denise died in 2006 at the age of ninety-four. Annie Beck, one of the children she sheltered, later said, “She was like a mother to us. She saved our lives.” Eighty-three children entered her convent seeking safety, and all eighty-three survived.
