Lee, who has been in catechism classes for two years, participated in a 21-day pilgrimage undertaken by relatives of the victims, carrying a cross in honor of the slain children. The families said they gave the cross to the pope.
The relatives also presented the pope with a tiny yellow ribbon, a symbol of support for the ferry victims. The pope took the ribbon and wore it on his robe during the Mass.
A larger-than-normal crowd of more than 10,000, according to police, on Friday joined what has become a regular rally by family members of victims of the ferry sinking.
