Diana called it "amazing" that she was able to see and listen to the "representative of God on earth."
"You get to know another country through this experience," she observed, adding that she believes her participation in the papal events "will bring me closer to Christ."
For pilgrim Ramon Tallaj, the Pope's message "is clear."
Tallaj, a Latino who lives in the United States, explained that "the Holy Father came to tell the people about hope."
Even in the most oppressing circumstances, people need not lose hope if they can turn to their faith, he said, because ultimately "that is what matters."
Tallaj believes that apart from politics, faith and religion are "important for the human being." Although religion can be a force for social change, he added, any movement must begin with a profound renewal of faith.
Ultimately, Tallaj thinks Pope's visit will have a long-lasting effect in bringing about true change for the people of Cuba. "Now it is confirmed," he said. "This truly is a revolution square."
