At Manhattan University and on the Staten Island ferry, the “Dorothy Day,” theologian Kevin Ahern and George Horton and Carolyn Zablotny, who are all working toward Day’s canonization, talk with Shannon about the future of the Catholic Church and what it means to be a saint.

Longtime Catholic Worker volunteer and resident Jane Sammon and former Maryhouse chaplain Fr. Geoffrey Gneuhs tell Shannon about Dorothy Day's life at Maryhouse, the Lower East Side community that feeds and houses the poor.
