Chilean Catholics are training clerics and parishioners in abuse prevention and counseling victims, but not just abuse in church settings.

Pope Francis' letter asked "forgiveness of all those I have offended" and said he hoped to "be able to do it personally in the coming weeks."

The victims gave their testimony to another official after the original Vatican envoy had emergency surgery.

Pope Francis has visited other prisons, but this was the first time on his travels as pope that he visited one just for women. He was greeted by women standing with their babies in their arms. 

"Today people my age feel very alone, and that's why we are always on social media. We want to feel part of something. And today the church doesn't offer people enough to help them feel they are part of a group."
