Pope Francis arrives Saturday, September 26, in Philadelphia for Mass. Photographer Connor Dwyer was selected as one of the top three winners in a campaign by Aleteia, a Catholic organization, to document the papal visit through social media.

The Knotted Grotto, outside the Basilica of Saints Peter and Paul, was a community art piece, led by artist Meg Saligman, that incorporated prayers written on strips of fabric.

People pass by a long line of port-a-potties. Philadelphia was prepared for the large crowds days ahead of time. "It was kind of surreal," Dwyer said.

Michael was one of the homeless men who received a ticket to attend the Saturday Mass. He was very excited to have gotten a ticket for his son as well.

The Aleteia social media campaign @Popeishope came up with the hashtag #goodiswinning so that people could share their experiences with the Pope's visit and follow along during his trip.

Chris is from North Philly, and his dream is to be a motivational speaker. He has had 15 of his friends or family members killed in violence related to gangs or drugs. He hopes to be able to encourage youths to take a path in life that will be filled with hope and success.

Dwyer said, "The Philly police department had such a positive presence at the events. They worked long hours but said that we made it easy on them. This motorcycle officer stopped to take a group photo."

Yonathan is a photographer who came all the way from Minnesota to capture the event. He was interacting with and updating the Latin crowd via social media.

People eagerly prepare their phones to capture imagery as they wait for the Pope to pass by.
