Book cover of Letters from A Skeptic: A Son Wrestles with His Father's Questions About Christianity

Tom Rudelius Author Of Chasing Proof, Finding Faith: A Young Scientist’s Search for Truth in a World of Uncertainty

From my list on why a scientifically-minded person can believe in God.

Why am I passionate about this?

I am a theoretical physicist and a practicing Christian. I was raised in a very loving but nonreligious household, and I didn’t seriously consider the possibility of God’s existence until I was a college student, when my twin brother came to faith and started to talk with me about it. In my subsequent journey to faith and the years thereafter, I read a number of books that changed my perspective on religion and convinced me that I could believe in God without compromising on my scientific view of the world. Chasing Proof, Finding Faith is the story of the journey I took, and the strange new world of faith I found on the other side.

Tom Rudelius Why did Tom love this book?

Letters from a Skeptic was the first book about religion that I read in my journey to faith.

The book consists of an actual correspondence between Edward, a skeptic, and Gregory, his son, a pastor. Reading this book as a skeptic myself, I resonated deeply with the objections raised by Edward. But time and time again, I was surprised at the thoughtfulness of Gregory’s responses. I wasn’t completely convinced at first reading, but I was intrigued enough to read further.

What is this book about?

Greg Boyd and his father, Ed, were on opposite sides of a great divide. Greg was a newfound Christian, while his father was a longtime agnostic. So Greg offered his father an invitation: Ed could write with any questions on Christianity, and his son would offer a response.

Letters from a Skeptic contains this special correspondence. The letters tackle some of today's toughest challenges facing Christianity, including

Do all non-Christians go to hell?
How can we believe a man rose from the dead?
Why is the world so full of suffering?
How do we know the Bible was divinely inspired?…


Book cover of Without God, Without Creed: The Origins of Unbelief in America

John Loughery Author Of Dorothy Day: Dissenting Voice of the American Century

From my list on religion in an age of doubt.

Why am I passionate about this?

Like many Americans, I consider myself uncertain about religion, though that may be less true now that I have come to know the life of Dorothy Day, the radical Catholic activist. She has that effect. Along with the writers below, Dorothy Day has brought me back to thinking of faith in terms that I could find meaningful, to a sense of religion that is about something other than a set of rules and doctrines based on narrow readings of the Bible and the rigidity of men (yes, always men) in positions of power. I grew up a deeply religious child, became a confirmed atheist for decades, but now, in part because of this book, find myself in a different if still uncertain place.

Turner asks a great question. How did the United States go from being the deeply religious society of the Puritans and the Founders to a culture of widespread unbelief, especially among the well-educated? His astute analysis of 19th-century America explains why and how agnosticism and atheism gradually became socially acceptable alternatives to faith. As Turner sees it, attempts to “explain” God and fit the Divine into a more rationalistic, scientific, and anti-mystical framework, and the deadening hand of dogma, helped pave the way for a culture resistant to the very idea of God.

What is this book about?

Until the 19th century, atheism and agnosticism were viewed as bizarre aberrations. But atheism emerged as a viable alternative to other ideologies. How and why it became possible is the subject of this cultural revolution.


Book cover of Comedy Sex God

Elizabeth Kendig Author Of Chase You

From my list on spirituality that take the weird out of the woo.

Why am I passionate about this?

Despite a successful editorial career and thriving beauty business, in my 30s I remained plagued by a depression and crippling perfectionism. What began as a self-help bender and journalistic endeavor to explore every holistic experience I could get my hands on became a way of life—and saved my life. When my spiritual mentor Monica Lawson introduced me to the Other Side and how to work with them to find clarity and purpose, it clicked: we could teach others to do the same. Our mission is to take the weird out of the woo and make spirituality accessible for everyone. It’s your birthright to chase you. We’re simply here to show you the way.

Elizabeth Kendig Why did Elizabeth love this book?

In this comedic yet deeply personal account of his tumultuous spiritual journey, Holmes shares his path from dogmatic religious upbringing to painful agnostic skepticism as a young adult to ultimately discovering a powerful connection with himself and the unknown with levity and relatability. That my husband and brother both devoured this book—and compared notes on it—gives me hope that we have entered a cultural moment when open spiritual discourse and examination by and among men is not only underway but being met with a standing ovation.

1 author picked Comedy Sex God as one of their favorite books, and they share why you should read it.

What is this book about?

Part autobiography, part philosophical inquiry, and part spiritual quest, Comedy Sex God is a hilarious, profound, and enlightening romp around the fertile mind of stand-up stand-out, podcast king, and HBO superstar Pete Holmes.

Pete Holmes is a sold-out-every-night stand-up comedian with two HBO specials and the host of the hugely successful podcast You Made It Weird, and he was the creator-star of the hit HBO show Crashing. But it wasn't always roses for Pete. Growing up, Pete was raised an evangelical Christian, but his religion taught him that being "bad"-smoking, drinking, having doubts or premarital sex-would get him sent to…


Book cover of Charles Fort: The Man Who Invented the Supernatural

Nicole Cushing Author Of Mothwoman

From my list on paranormal investigation.

Why am I passionate about this?

I’m a weirdo, so of course I’m attracted to the idea that the universe may be weird, too. I like the idea that the universe is able to hold itself together ninety-nine percent of the time, but every once in a while it just has to let its freak flag fly. Even if paranormal experiences are nothing more than waking dreams, they may still be worth our attention (the same as any dream). Even if such experiences aren’t objectively “real”, they’re subjectively fascinating. I love exploring the line between reality and unreality. Like Fort, I don’t believe it to be as cut and dry as mainstream science would have us believe.

Nicole's book list on paranormal investigation

Nicole Cushing Why did Nicole love this book?

Charles Fort was the o.g. paranormal investigator. One hundred years ago, he made a sweeping study of all the weird stuff mainstream science refuses to examine. Even now we use the word “Fortean” to describe the study of ghosts, bigfoot, ufos, ESP, etc. Steinmeyer’s biography reveals the complicated man behind the adjective. 

Was Fort a kook? Not really. Steinmeyer reveals him to be more of a gadfly, playfully thumbing his nose at science but never investing too much belief in his own eccentric theories, either. For Fort, the real and the unreal were two sides of the same coin. His quarrel was with those who insisted the quarter only had heads and refused to investigate the possible existence of tails.

What is this book about?

'I am the first disciple of Charles Fort. Henceforth I am a Fortean'

Since Ben Hecht wrote this line in reviewing The Book of The Damned in 1919, Charles Fort - whose very name spawned an adjective, Fortean, defined in the Oxford English Dictionary as 'relating to or denoting paranormal phenomena' - has so divided opinion that to Theodore Dreiser he was "the most fascinating literary figure since Poe;" to The New York Times he was "the enfant terrible of science;" and to HG Wells he was "one of the most damnable bores who ever cut scraps from out of…


Book cover of Lives of Girls and Women

William Illsey Atkinson Author Of Sun's Strong Immortality

From my list on well-written slam-bang adventures.

Why am I passionate about this?

I had a rotten childhood. Stuck in bed with asthma, I couldn’t do sports; but I could roam space and time with books, especially science fiction. Yet when I tried to re-read my beloved sci-fi titles as an adult, I got a shock. The books with sound science had terrible writing; the well-written books were full of scientific schlock. I realized that if I wanted sci-fi that was both technically astute and rewarding to read, I’d have to write it myself. And so I did.

William's book list on well-written slam-bang adventures

William Illsey Atkinson Why did William love this book?

Great adventure doesn’t always mean jungles, star-wastes, or derring-do. The human heart – what one poet called "the wilderness behind the eyes" – can be as electrifying as any firefight. In this tradition, Alice Munro won the 2013 Nobel Prize in Literature. Lives of Girls and Women is her second novel, and like all great adventure stories will tell you more about yourself than you ever suspected. As Sir Walter Scott said of Jane Austen: "That young lady has a talent for describing the involvements and feelings and characters of ordinary life."

By Alice Munro,

Through the women and men she encounters, Del becomes aware of her own potential and the excitement of an unknown independence. Alice Munro's previous books include "Dance of the Happy Shades" and "The Beggar Maid", which was nominated for the 1980 Booker Prize.


Book cover of The Pilgrim's Progress

Kevin Hart Author Of Dark-Land: Memoir of a Secret Childhood

From my list on finding yourself.

Why am I passionate about this?

Hello, I write poems, lots of them, and also lots of books about Christianity. I grew up in London and lived for my first thirteen years deep within myself, in a kind of fog that prevented anyone from knowing me, including myself. Then, one day, when I was thirteen, in the middle of a math class, everything changed for me. I entered a wholly new world. I went from being at the bottom of the class to the top of the class; I started publishing poems. I started a quest to find myself anew, cutting through the fog, and that quest ended with me teaching Divinity at Duke University. 

Kevin's book list on finding yourself

Kevin Hart Why did Kevin love this book?

When I was ten years old, I listened to a shortened version of this astonishing narrative while at school. I would wish the whole week away to hear the next installment! It’s the allegory of the main character, Christian, who leaves the City of Destruction for the Celestial City. His parents remain in Dark-Land.

When I wrote my memoir, I called it Dark-Land in homage to Bunyan, as a way of thinking about London in the years of post-war austerity when I was growing up, and as a way of making sense of how my parents kept me in the dark about all sorts of things in the family. Only when I started to write my memoir did I finally find out the family secrets.

What is this book about?

With an Introduction by Professor Stuart Sim.

John Bunyan was variously a tinker, soldier, Baptist minister, prisoner and writer of outstanding narrative genius which reached its apotheosis in this, his greatest work. It is an allegory of the Christian life of true brilliance and is presented as a dream which describes the pilgrimage of the hero - Christian - from the City of Destruction via the Slough of Despond, the Hill of Difficulty, the Valley of the Shadow of Death and Vanity Fair over the River of the Water of Life and into the Celestial City.

Roxane Lapa Author Of Answering The Atheist: Good Questions Deserve Straight Answers

From my list on Christian apologetics.

Why am I passionate about this?

I’ve been a Christian for 30+ years, and have had many questions about the Bible and theology. In order to answer my own questions, I’ve consumed scores of apologetics books, articles, videos, and podcasts, as well as studied the Bible itself, with lexicons and commentaries.

1 author picked Answering the Objections of Atheists, Agnostics, & Skeptics as one of their favorite books, and they share why you should read it.

What is this book about?

Many arguments from atheists, agnostics, and skeptics are difficult, or at least intimidating, for most Christians to answer. With clear reasoning and understandable language Ron Rhodes provides readers with the explanations and scriptural background they need to respond to common arguments against faith including:

There is no such thing as absolute truth. Genesis is a myth, not a scientific account. A loving God cannot exist--there is too much evil and suffering. If God created all things, how did He create Himself? Sin is an outdated concept.

With this resource, Christians will be able to confidently respond to logical arguments against…


Book cover of Being and Nothingness

John H. Sibley Author Of Being and Homelessness: notes from an underground artist

From my list on understanding homelessness and existentialism.

Why am I passionate about this?

I am a Chicago-based artist, author, veteran, and teacher. I studied at the American Academy of Art in Chicago before enlisting in the United States Air Force in 1968 during the bloody Tet Offensive during the Vietnam era. Upon my discharge I got my BFA in 1994. I got convicted for a crime I did not commit, and I became a homeless-existential artist on Chicago’s mean streets for six months. I got hired by an Acoustic company, and I married and worked for twenty-seven years while raising a family. I now work as an art teacher. All my nonfiction books chronicle different episodes in my life. 

John's book list on understanding homelessness and existentialism

John H. Sibley Why did John love this book?

When I was a homeless artist living on Chicago’s cold streets for six months, it was hard for me to believe in a compassionate Judeo-Christian God. It was difficult for me to reconcile how a just and benevolent God would let African pregnant women be thrown into the Atlantic Ocean and perish with thousands of other slaves.

That is why I became agnostic and was attracted to Sartre’s belief in the essential freedom of individuals, and he also believed that as free beings, people are responsible for all elements of themselves, their consciousness, and their actions. It made me question why I was homeless. Was it because of bad choices in life? Or was it just the experience of being a black male in a racist capitalist society?

Sartre became an existentialist because of the war and an encounter with Merleav Ponty, who taught him the political dimension of human…

Revisit one of the most important pillars in modern philosophy with this new English translation—the first in more than 60 years—of Jean-Paul Sartre’s seminal treatise on existentialism. “This is a philosophy to be reckoned with, both for its own intrinsic power and as a profound symptom of our time” (The New York Times).

In 1943, Jean-Paul Sartre published his masterpiece, Being and Nothingness, and laid the foundation of his legacy as one of the greatest twentieth century philosophers. A brilliant and radical account of the human condition, Being and Nothingness explores what gives our lives significance.

Roxane's book list on Christian apologetics

Roxane Lapa Why did Roxane love this book?

Andy Bannister has written this book in response to popular one-liners by new atheists, particularly Dawkins. Tired retorts comparing God to Santa Claus and the tooth fairy are hilariously dealt with by the author's dry British humour. I had a good couple of chuckles in this book. I particularly loved his imaginary friend who claimed he stole the Venus di Milo's arm, and also how he sarcastically puts trademark symbols on the words 'Science' and 'Reason'. Still, I think he does a good job of preventing his teasing from becoming a poo-flinging contest. Such a talented writer - loved this book!

What is this book about?

In the last decade, atheism has leapt from obscurity to the front pages: producing best-selling books, making movies, and plastering adverts on the side of buses. There's an energy and a confidence to contemporary atheism: many people now assume that a godless scepticism is the default position, indeed the only position for anybody wishing to appear educated, contemporary, and urbane. Atheism is hip, religion is boring. Yet when one pokes at popular atheism, many of the arguments used to prop it up quickly unravel. The Atheist Who Didn't Exist is designed to expose some of the loose threads on the…
