The spiritual practice of speaking in tongues –a form of communication with the divine through speaking words in an unknown or unrecognizable language– has invited a lot of speculation and skepticism over the years. To many, it seems like the stuff of horror movies, or old-timey religious revivals. But charismatic Christianity, for which speaking in tongues is a central practice, is one of the fastest growing Christian movements in modern history. So why has it not only persisted, but recently gained momentum? What exactly is happening to the mind and body when people engage in this practice?

We’ll talk to Josh Brahinsky, anthropologist and author of a forthcoming book on speaking in tongues, about his years researching people taking part in this practice, and why it’s far less rare and extreme than many people think. And how neuroscience is showing real changes in the brain that point to tongues as an effective method of prayer and even mindfulness. We’ll also talk to Shavon Gartrell, youth pastor at Glad Tidings Church in San Francisco, about what it feels like to let go, drop in and give her tongue to God.

What is prayer? And why do it? People pray for all kinds of reasons, and in all kinds of ways: alone, together, aloud, in silence, from memory, or from instinct. But whatever form it takes, there’s a reason prayer has been part of just about every spiritual tradition out there: its effects run deep.

On this episode, we’re digging into the science and spirit of prayer. We’ll talk to neuroscientist Andrew Newberg about what prayer does to our minds and bodies, and how it helps shape us as people. And friend of the show Rabbi Shira Stutman will return to explore how people can find meaning, connection and growth through intentional practice, whatever their beliefs may be.

Andrew Newberg is the director of research at the Marcus Institute of Integrative Health and a physician at Jefferson University Hospital. He is the author of several books on the neuroscience of spirituality, including How God Changes Your Brain and The Rabbi’s Brain. Find out more about his work on his website.

Shira Stutman is a nationally known faith-based leader and changemaker, currently serving as Senior Rabbi at Aspen Jewish Congregation. She is also co-host of the podcast Chutzpod and author of the book The Jewish Way to a Good Life: Find Happiness, Build Community, and Embrace Lovingkindness.

There's a lot of talk these days about a crisis of masculinity. But is it a genuine problem or just another culture war talking point?

In this special episode, we’ll talk to writer and researcher Richard Reeves about the real and worrying data around the male struggle for meaning and purpose, and what role community and ritual can play in helping men find answers. We’ll also hear from Dr. Russell Moore and Pastor Rasool Berry about how and why religion can help support men, but also the dangers it can pose if they follow it down the wrong path. And we’ll hear directly from some young men about the challenges they’re facing around identity and the comfort they’re finding in Christian community and scripture.

Richard Reeves is the president of the American Institute for Boys and Men and the author of the book Of Boys and Men: Why the Modern Male Is Struggling, Why It Matters, and What to Do about It. Learn more about his work on his website.

Hey listeners, we'll be back in two weeks with a special episode looking at the multiple challenges facing men in America today. But while you wait, we wanted to share an episode from Season 2 of our show that feels especially relevant to that conversation. Think of it as a prequel or primer, because part of the problem, and possibly part of the solution, may have to do with how boys become men in the first place. We hope you enjoy!

When you’re a teenager, you’re kind of between two worlds. You’re leaving the comforts and carefree days of childhood behind and stepping into the challenges and responsibilities adulthood brings. But when exactly should you make that change? And, more importantly, how can rites of passage help?

Join Dave as he talks with psychologist Leah Somerville and religion scholar Connor Wood to explore the adolescent mind and how rituals can help it learn to “adult.”

For centuries, Western science and philosophy have struggled to explain what consciousness is and where it comes from. What if the answer to both those questions is: everything?

On this episode, we dive into panpsychism: the idea that consciousness may not be limited to humans, or even living beings, but could be a basic property of reality itself. We’ll talk to philosopher Philip Goff about why this idea is gaining attention in academic circles, and to theologian Joanna Leidenhag about how panpsychism aligns with spiritual traditions from across cultures and throughout history. We’ll also ask: could this strange-sounding idea reshape how we understand ourselves and our place in the world?

Philip Goff is a professor of Philosophy and the author of Why?: The Purpose of the Universe, Galileo’s Error: Foundations for a New Science of Consciousness and many other publications about panpsychism. Find out more about his work on his website.

Joanna Leidenhag is a professor of Theology and Philosophy and the author of the book Minding Creation: Theological Panpsychism and the Doctrine of Creation. Find out more about her work here.

People find faith or change faiths for many reasons: marriage, raising a family, dealing with grief or crisis. But sometimes it happens the other way around… faith finds you. A believing takes hold, a sense that something divine is there. And maybe not in the way or role that you might have expected.

It’s not uncommon. Data show that these types of experiences happen to about 30% of people. On this episode we’ll talk to one of these people –New York Times columnist and best selling author David Brooks– about his unexpected encounter with faith and what came after.

Many would agree there are few things better than sharing a delicious meal with the people you love, which is one reason why breaking bread together is a cornerstone of religions the world over. But so too is the opposite - going without food.  From Ramadan to Yom Kippur to Lent, fasting is an important ritual in many faiths. But why do so many religions periodically take away the very thing that nourishes our bodies and souls?

On this episode we'll talk with Khalil-Abdur Rashid about the role fasting plays in Islam, and why not eating and drinking is actually the easy part.  And we'll talk to Adam Cohen about some new research that suggests even one day of fasting could help deepen religious commitment and overall well being.

Imam Dr. Khalil Abdur-Rashid is the first full-time University Muslim Chaplain at Harvard University, Instructor of Muslim Studies at Harvard Divinity School, and Public Policy Lecturer at the Harvard Kennedy School of Government.

We often think of belief as a religious or cultural idea that is a hallmark of modern humans. But what if the early sparks of belief burned in our ancestors’ minds long before modern humans walked the earth? What if beliefs about some of the biggest questions out there, like what happens after death, weren’t just pondered by Homo sapiens?

On this episode, evolutionary anthropologist Agustín Fuentes takes us on a journey spanning millions of years, from our primate relatives in the deep past to the complex spiritual and cultural traditions we know today. Along the way, we’ll learn how the capacity for belief has helped shape our species and why it remains a powerful force in our lives today.

Agustín Fuentes is a Professor of Anthropology at Princeton University and the author of the books Why We Believe: Evolution and the Human Way of Being and The Creative Spark: How Imagination Made Humans Exceptional.
