Pope Benedict XVI is on a state visit to Cuba this week hoping to highlight the role of the Roman Catholic Church on the Communist island, as well as making subtle push for change.

Benedict called for "renewal and hope, for the greater good of all Cubans," during a speech on Tuesday. "I have also prayed to the Virgin for the needs of those who suffer, of those who are deprived of freedom, those who are separated from their loved ones or who are undergoing times of difficulty."

But the Cuban government was quick to say that there "will not be political reform" in the country as a result of the pope's visit.

NBC News' Mark Potter is in Havana. He answered interesting reader questions about Benedict's visit earlier today.
