In our time, some associate the word “religion” with rigid dogma and the excesses of institutions. The word “spirituality” on the other hand can seem to have little substance or form. The word “faith” can appear as a compromise of sorts, pointing to the content of religious tradition and spiritual experience. The truth is, all of these words are vague in the abstract. They gain meaning in the context of human experience.

In this show, we’ll explore the connotations of the word “faith” in four traditions and lives: Buddhism, Judaism, Christianity, and Islam. We’ll speak with Sharon Salzberg, Rabbi Lawrence Kushner, Anne Lamott, and Omid Safi.

Many Americans received a violent introduction to Islam in September 2001. And yet, only one quarter of Americans told pollsters then that they considered Islam itself to be more likely than other religions to encourage violence in its believers. In the last two years, that figure has almost doubled. The specter of violence committed in the name of Islam has become as routine as it is shocking, especially at present in Iraq.

In this hour, we take a critical look at what is happening in Islam from inside a practice of that tradition. Krista discusses the present escalation of violence in the name of Islam with a practicing Muslim and leading scholar of Islamic studies, Vincent Cornell. He paints a bleak picture of chaos and drift within Islam which may presage renewal or the continued decay of the religion he loves.

Many of history’s greatest scientists considered their work to be a religious endeavor, a direct search for God. Pioneers like Newton, Copernicus, and Galileo believed that their discoveries told humanity more about God’s nature than had been known. Beginning in the early 18th century, science and religion came to be at odds — the gap widening most famously with the publication of Darwin’s On the Origin of Species.

In recent years, a new dialogue has begun, driven by leading scientists across the world. Host Krista Tippett explores with three scientists, each of whom is working in a field that’s rapidly advancing our understanding of what it means to be human. From very different perspectives, they suggest that our most sophisticated 21st-century discoveries may be driving us back to questions of faith.

The theory of the “God gap” — often broadly suggesting that religious Americans are conservative and will vote Republican while non-religious Americans are liberal and will vote Democratic — has been prominent in press reporting and political maneuvering in the 2004 presidential race. At their recent conventions, both parties seemed to grapple with faith dynamics and respond to the perceived God gap in interesting, unexpected ways.

Krista speaks with Steven Waldman, who covered the 2004 Democratic and Republican conventions for religious messages, images, and language. He says that, strictly speaking, the God gap is a myth. We’ll look beyond the headlines about the political gulf that reportedly separates religious and secular Americans.

Religious fundamentalism has reshaped our view of world events. In this show, host Krista Tippett explores the appeal of fundamentalism in Islam, Christianity, and Judaism, as experienced from the inside. Three accomplished men, who were religious extremists at one time in their lives, provide revealing insight into the spiritual and cultural dimensions of fundamentalism. They also discuss religious impulses which counter the fundamentalist world view and helped them break free.

We speak with Washington insider Joseph Califano, a devout, lifelong Catholic, who held key positions inside the Kennedy, Johnson, and Carter administrations. Califano provides frank insight into the practical difficulties of applying religious ideals in the political arena.

Pentecostalism began on the American frontier, and it has become one of the largest expressions of global Christianity. In less than a century, it has grown to hundreds of millions of adherents. Today, Pentecostalism is pan-denominational. There are charismatic Catholics and Lutherans, unaffiliated Pentecostal communities, and established Pentecostal traditions, most prominently the Assemblies of God.

Krista Tippett speaks with a theologian about the rise of Pentecostal worship among African-Americans in every denomination and a sociologist on her study of modern day Pentecostals — whom she sees as mystics among us.

In remembering the legacy of four World War II chaplains — Catholic, Protestant, and Jewish — who went down together with their torpedoed ship in 1943, we speak with David Fox, nephew of one of the chaplains. We also hear interviews with surviving veterans and veterans of the German ship that torpedoed them. Finally, a conversation with author, poet, and Vietnam War veteran Bruce Weigl. His most recent book, The Circle of Hahn, chronicles the long personal journey he has made back to Vietnam and to the adoption of a beloved Vietnamese child. The paradox of his life as a writer, he says, is that the war ruined his life and gave him his voice.

In the coinciding seasons of Passover and Easter, two world religions celebrate their core stories in ritual and worship. Each of these sacred holidays is based on a key biblical story of suffering and deliverance.

The Christian Holy Week commemorates the death of Jesus leading to the Easter celebration of resurrection. In eight days of Passover, Jews remember and reenact the exodus story.

What can ancient narratives of violence and miracle have to say to contemporary audiences? Host Krista Tippett explores faithful ways of living with these stories and giving them modern sense with featured readings from the Bible, words of a 14th century mystic, and poetry from Wendell Berry.

The religious landscape of Iraq is complex and somewhat enigmatic to the western world. Nearly 97% of Iraq’s 25 million people are Muslim, and a majority of Iraqis are Shiite rather than Sunni. What does that mean? And how powerful is the prominent cleric Ayatollah Ali al Sistani who has effectively challenged the American-led coalition. Could he become another Islamic revolutionary like Iran’s Ayatollah Khomeini?

As part of Iraq’s rebuilding process, the Iraqi governing council agreed on an interim constitution that cites Islam as a source — but not the primary source — of future legislation. Approval of the interim constitution was delayed first by violence, and then by a group of Shiite council members who raised objections to elements within it. Host Krista Tippett speaks at length with Iraqi-American professor and advisor, Ahmed al-Rahim, for insight into the unfolding new relationship between mosque and state in Iraq.

Host Krista Tippett explores the practical implications of spirituality at work with Federal Bureau of Investigations special agent and whistleblower Coleen Rowley and syndicated columnist Tim McGuire.

In May 2002, Rowley wrote a now-famous 13-page letter to Robert Mueller, Director of the FBI. In it, Rowley raised serious and detailed concerns about how the FBI had handled leads prior to the September 11th attacks.

Religious pronouncements seem to have become mandatory for the Democratic candidates in this election. Yet it’s been easy to deride the resulting sound bites that are widely repeated—such as Howard Dean’s proclamation of his favorite book of the New Testament: the Old Testament book of Job. Host Krista Tippett takes a larger view of what this election has to say about the role of religion in American life. Is it changing, and if so, what is substantive and important in that change?

At the center of our history of church and state is a troublesome irony. What began as an attempt to guarantee religious tolerance in the new world has at various times been commandeered by the most chauvinistic movements America has known. In spite of this, religious liberty has survived as an American ideal—one which we continue to test.

We live in a world of increasing religious pluralism—diversity beyond the imagining of our nation’s founders—which suggests fresh nuance to the meaning of religious liberty. This much is clear: our modern conversation has few connections to the social, political, and religious impulses that led to the First Amendment.

Host Krista Tippett and her guests revisit the history and meaning of separation in thought-provoking and, at times, unsettling ways. Charles Haynes talks about his work in the American public school system—the arena in which our modern debates often center. Philip Hamburger describes his research into the surprising, and largely forgotten, origins of separation of church and state. And, Cheryl Crazy Bull speaks about the loss and reemergence of religious expression in tribal public life.

In recent years, the practices of prayer have been evolving for many religious traditions. Even western medicine is looking at prayer as it expands its concept of healing. In this program, we consult several people from a variety of practices about the role of prayer in their lives.

The General Convention of the Episcopal Church has sharpened our culture’s intensifying focus on homosexuality. In a year of political and religious milestones for gays and lesbians, Gene Robinson became the first openly gay man to be elected an Episcopal Bishop. There were 11th-hour allegations of impropriety. But in the end, the laity, clergy, and House of Bishops of the Church confirmed his election.

This week, we set aside the ins and outs of the Robinson controversy. The public furor over this event flows, in part, from our culture’s confusion over what it might mean to morally condone homosexual relationships. And Gene Robinson aside, this issue remains an ongoing source of bitter debate among Anglicans and in most of the mainline churches in this country.

How can people of faith reach radically different conclusions while living in the same tradition? Host Krista Tippett engages two Episcopal bishops on either side of the matter in a thoughtful conversation that aims to clarify our understanding of the religious issues at stake.

Over the last four decades, women’s roles have changed dramatically — at home, in the work force and in religious institutions as well. In America, resistance to this is often couched in religious terms. Where there is a backlash against feminism and its repercussions, it is often embodied in religious practice. Host Krista Tippett speaks with three devoutly religious women who also call themselves feminist.

Christian scripture and tradition have overwhelmingly shaped American attitudes toward sexuality. And in the past year, our national attention has been riveted on sexual scandal within the Catholic Church. In this program, we crack open the difficult subject of Christian tradition and healthy sexuality. What is the positive sexual ethic of the Bible, beyond the identification of sin? What does sexuality have to do with the human spirit and how might this change they way it is discussed in communities of faith?

More than any crisis in modern memory, the War on Terror—including the current U.S. military presence in Iraq—is being debated in religious, usually Christian, terms. We explore the nuances of that debate with a former war correspondent, a political theorist, and a renowned preacher. We ask how and whether Christian principles really make a difference at this moment in our national life—and if not, why not?
