Pope Francis knelt at the feet of the leaders of South Sudan, begging them to give peace a chance and to be worthy "fathers of the nation."

This week on "Inside the Vatican," we cover the ecumenical retreat the Vatican is hosting for South Sudanese leaders.

The Vatican described the retreat as “a propitious occasion for reflection and prayer, as well as an occasion for encounter and reconciliation.”

Aboard the papal plane, Francis spoke with reporters about the need to build solidarity, not barriers.

Pope Francis suggested four actions were needed to assist migrants in their plight today: “accept; protect; promote; and integrate.”

Pope Francis said he hoped his visit would “strengthen the bonds of sincere friendship,” mutual respect and cooperation between Christians and Muslims “and enable our communities to prepare a better future for coming generations.”
