Father Jack Wall, the pastor emeritus at Old St. Pat’s, was present in St. Peter’s Square during the events on Thursday, sharing his thoughts on its significance for Catholics in Chicago.

“Just an amazing gift to experience someone who came from one of our neighborhoods, I actually grew up in the same communities he did and went to the same grammar school, and to see somebody coming from our toots and raised by his family and good families that come out of our Church experience, it’s just amazing,” Fr. Wall said. “One of us. There’s a great line in scripture, ‘What good can ever come out of Nazareth?’ It has that same feeling from Dolton, Illinois. This man has come forward and all of his gifts and talent will now be given to the world…I get very emotional even thinking about it.”
