CLEVELAND -- Hundreds of thousands of people are on their way to witness history at the Vatican this weekend.
For the first time ever, two popes will be made saints.
Close to a million pilgrims are expected to jam the streets.
Pope John the XXIII convened the second Vatican Council that modernized the ancient faith.
He led for five years.
Pope John Paul II served for 26 years and was known for bringing down communism and taking a more conservative approach to the Catholic doctrine.
"You have two men who were pastors, reached out to the world, made a difference in the lives of the world of Catholics and brought the person of Christ to the center. Why not have these two men together to show us how we can be saints?" said the Rev. Mark Latcovich from Borromeo Seminary in Wickliffe.
Latcovich met John Paul back in 1999, as did many Clevelanders 30years prior earlier when John Paul visited Saint Stanislaus as a cardinal.
"Someone we lived through and grew with, it's a very special time for all, not just Catholics but for so many people around the world today," said one parishioner.
The historic ceremony will be broadcast around the world in 3-D and followed on social media.
It even has its own twitter handle, @2popessaint.
For some, it's such an important event, they plan to wake up in the middle of the night to watch it all.
"You feel really connected. To me that's what Catholicism is, a direct communication personally all around the world to all these people who believe the same thing," said parishioner Peter Petretich.
SS. Peter and Paul Parish in Garfield Heights will also open its doors at 3:30 a.m. for the live broadcast.
