Pope Francis
Francis has also tried , unsuccessfully , to foster dialogue between the government and the opposition in Venezuela , Berry said . 
Pope Francis was scheduled to arrive in Colombia on Wednesday to urge reconciliation in a country deeply divided over the terms of a peace deal that the pontiff helped bring to fruition . 
Francis closely followed the negotiations and publicly pushed both sides toward the agreement , making at least two phone calls to President Juan Manuel Santos , who was awarded the Nobel Peace Prize for his efforts . 
Francis "gave us encouragement at difficult moments ," Santos said last week in downtown Bogota at the premiere of a government-sponsored documentary chronicling the four years of negotiations in Havana . 
The visit by Francis is generating enormous interest , with more than 4 million faithful expected to see him , including 700,000 at an outdoor Mass in Bogota 's Simon Bolivar Park on Thursday and an even bigger crowd at Medellin 's Olaya Herrera international airport on Saturday . 
Colombia , which ranks behind only Brazil and Mexico among Latin American nations with the most Roman Catholics , is the fifth Latin American nation Francis is visiting since becoming pope in 2013 .
