The Kennedy family is well known for their Catholic faith.  One member, Mark Shriver, a nephew of the nation’s one and only Catholic president, struggled with his relationship with the Church, describing himself onetime as “skeptical, disillusioned, and uncertain whether the Church remained a force for good in the world.”  Shriver has written a new book, “Pilgrimage:  My search for the real Pope Francis”.  He stopped by @greaterboston to discuss it with Jim.
