>> reporter: good morning, natalie. at capacity, st. peter's square behind me can hold 80,000 people. but officials are expecting ten times that number to come here and witness history, because on sunday, the catholic church for the first time will canonize two popes together. all roads lead to rome for the world's catholics . the script from chicago joining one million pilgrims to see them become saints. pope john opened the streets to the world in 1962 , convening the second vatican council that modernized this ancient faith. he led the church for just five years. john paul ii served for 26, a major figure on the world stage, the pope from poland helped bring down communism. he was a charismatic leader with a more conservative approach to catholic doctrine. at his funeral in 2005 , millions chanted sainthood now. drowning out dissent.
