They echoed the Vatican's account, saying the pope was "very upset and very distressed" on hearing their stories.
Speaking to state broadcaster ARD on Tuesday, a 63-year-old man from Stuttgart who was abused by two nuns as a child in a church boarding school, said the pope "was stunned, and his voice got quieter and quieter."
After hearing the man's description of his experiences, the pope told him, "I am very upset. That is truly awful, what was done to you." The pope also promised that the cases would be investigated.
