Pope Francis was finally able to meet Cuba's Fidel Castro on Sunday after holding a mass at Havana's Revolution Square, which was previously reported by HNGN. Pope Francis' trip aims to show the whole world how the United States and Cuba could be the set the best example of reconciliation.

Pope Francis met with the 89-year-old known revolutionary of the 20th century in his home where they talked about religion and world affairs for about 40 minutes, Reuters reported.

Father Federico Lombardi, the spokesman for the Vatican said that the historical meeting between the head of the Catholic church and Castro with his family has been "very relaxed, fraternal and friendly."

During the Holy See's homily on Sunday, he highlighted that we should avoid from judging others by not "looking to one side or the other to see what our neighbor is doing or not doing."

"Whoever wishes to be great must serve others, not be served by others," he added, according to the Beaumont Enterprise. "Service is never ideological, for we do not serve ideas, we serve people."

"There is a way to go about serving which is interested in only helping 'my people,'" Francis said, which was interpreted as a slight nudge towards the communist government, CNN reported. "This service always leaves 'your people' outside, and gives rise to a process of exclusion."

Pope Francis is Latin America's first pope and is regarded by Cuban for initiating in warming the long cold relationship between their nation and the United States. After the visit to Cuba, he will then proceed to Washington which will be his very first visit to the U.S.
