"Certainly, the historic influence of Calvinism also influenced the Catholic Church, fragmenting her, but with this pilgrimage to Rome, we are witnessing that the Catholic faith is united. I am hopeful about the future, especially after this week. We have all known one another personally, by name, during the pilgrimage. Many are young people who have deepened their faith."
