The renowned actor as you’ve never heard him before. He has appeared in over 100 films, including Apocalypse Now. He’s best known on television as President Bartlet in The West Wing. But Martin Sheen, born and still legally named Ramón Estévez, has had another lesser-known life as a spiritual seeker and activist. He returned to a deep and joyful Catholic faith after a crisis at the height of his fame in mid-life. He’s been arrested over 60 times in vigils and protests. “Piety is something you do alone,” he says. “True freedom, spirituality, can only be achieved in community.”

To be Evangelical is not one thing, even on abortion. This conversation about Christianity and politics with three generations of Evangelical leaders — Shane Claiborne, Greg Boyd, and the late Chuck Colson — feels more relevant in the wake of the 2016 election than it did when we first recorded it. We offer this searching dialogue, which is alive anew, to a changed political landscape.

Before Pope Francis, James Martin was perhaps the best-loved Jesuit in American life. He’s followed the calling of St. Ignatius of Loyola, the founder of the Jesuit order, to “find God in all things” — and for him that means being a writer of books, an editor of America magazine, and a wise and witty presence on Twitter, Facebook, and Instagram. To delve into Fr. Martin’s way of being in the world is to discover the “spiritual exercises” St. Ignatius designed to be accessible to everyone more than six centuries ago.

There’s a kind of brilliance that flashes up in early adulthood: an ability to see the world whole. Nathan Schneider has been able to articulate and sustain that far-seeing eye of young adulthood. He’s also a gifted writer, chronicling the world he and his compatriots are helping to make — spiritual, technological, and communal. At the Chautauqua Institution, we explore the wisdom of a millennial generation public intellectual on the emerging fabric of human identity.

Something of a celebrity in Quaker circles, Carrie Newcomer is best known for her story-songs that get at the raw and redemptive edges of human reality. This week, a musical conversation with the Indiana-based and born folk singer-songwriter who’s been called a “prairie mystic.” She writes and sings about the grittiness of hope and the ease of cynicism.

She became a national figure as the face of the “Nuns on the Bus.” Sr. Simone Campbell is a lawyer, lobbyist, poet, and Zen contemplative working on issues such as “mending the wealth gap,” “enacting a living wage,” and “crafting a faithful budget that benefits the 100%.” She is a helpful voice for longings so many of us share, across differences, about how to engage with the well-being of our neighbors in this complicated age.

She’s the tattooed, Lutheran pastor of the House for All Sinners and Saints in Denver, a church where a chocolate fountain, a blessing of the bicycles, and serious liturgy come together. She’s a face of the Emerging Church — redefining what church is, with deep reverence for tradition.

The idea of reciting an unchanging creed sounds suspicious to modern ears. But the late, great historian Jaroslav Pelikan illuminated ancient tradition in order to enliven faith in the present and the future. He insisted that strong statements of belief will be necessary if pluralism in the 21st century is to thrive. We take in his moving, provocative perspective on our enduring need for creeds.

“Let’s go back and look at our faith before it was reduced to a system, before it was reduced to a system of abstractions and beliefs. How can we rediscover our faith as a series of stories and as a series of encounters?” Brian McLaren on the evolution of Christianity and the meaning of progressive Evangelicalism.

The writers Flannery O’Connor and Walker Percy, social activist Dorothy Day, and the Trappist monk Thomas Merton — all four shared a complex Catholic faith. Paul Elie takes us on a kind of literary pilgrimage through a Catholic imagination that still resonates in our time.

The coming stage of evolution, Teilhard de Chardin said, won’t be driven by physical adaptation but by human consciousness, creativity, and spirit. We visit with his biographer Ursula King, and we experience his ideas energizing New York Times Dot Earth blogger Andrew Revkin and evolutionary biologist David Sloan Wilson.

Two Christian leaders are working to restore Christian engagement in the world. Gabe Lyons and Jim Daly discuss how they who are reshaping their part in common life, and the common good. This often surprising conversation addresses subjects like gay marriage, abortion, and the strident reputation that Christian evangelicals have earned in the past decade.

From The Daily Show with Jon Stewart to CNN, Joanna Brooks has become a go-to voice during our national inspection of Mormonism in this presidential campaign. As Mitt Romney makes history, we revisit our personal and revealing conversation with the Ask Mormon Girl blogger. She opens a window on Mormonism as an evolving and far from monolithic faith.

The second show from our recent trip to Istanbul. We meet a Dominican friar whose Christianity is inspired by the mystical tradition of Islam. And, an Eastern Orthodox bishop is creating what he calls a “dialogue of life” as a religious minority in this crucible of the ancient church.

An understanding of Easter from inside the Armenian Orthodox tradition that is at once mystical and literally down to earth. Vigen Guroian is a theologian who experiences Easter as a call to our senses. He is passionate about the meaning of grand ideas like incarnation, death, and eternity as revealed in life and in his garden.

Paul Brandeis Raushenbush opens up a hidden but possibly re-emerging influence in the DNA of American Christianity, reaching back to the Social Gospel movement at the turn of the 20th century. And, the Huffington Post religion editor shares what he’s learning about religion in this century’s evolving realm of technology.

A look back at the closest thing the early 20th century may have had to Oprah Winfrey. The flamboyant Pentecostal preacher Aimee Semple McPherson was a multimedia sensation and a powerful female religious leader long before most of Christianity considered such a thing. The contradictions and passions of her life are a window into the world of global Pentecostalism that touches as many as half a billion lives today.
