He spoke at the close of his second full day in Poland, where he is spending July 27-31 for World Youth Day. He's appearing on the balcony of the archbishop's palace each night after he returns in order to address the crowd of youth gathered below.
St. John Paul II began the tradition by speaking to youth from the balcony each time he visited his homeland as Pope. It was continued by Benedict XVI when he visited Poland in 2006, and is now Francis is following in the steps of his predecessors.
Earlier in the morning Francis went to the Auschwitz and Birkenau extermination camps, where an estimated 1.5 million people lost their lives during the Nazi occupation. He later stopped by a children's hospital to visit with the young patients and give them his blessing.
After leaving the hospital, Pope Francis traveled to Krakow's Blonia Park, where the youth participating in WYD performed a live reenactment of the Stations of the Cross.
In his speech to youth at the balcony window, Pope Francis noted how they are closed the day uniting to the suffering Jesus. However, Jesus didn't just suffer 2,000 years ago, but "he suffers today," the Pope said.
There are many people who suffer, including "the sick the homeless, the hungry, those who are doubtful in life, who don't feel happiness or salvation, or who feel the weight of their own sin," he said, noting that Jesus also suffers in the sick children he visited at the hospital earlier in the day.
