People today encounter a dizzying array of religious options. We might consider mystical faiths like Buddhism and Hinduism, historical religions like Islam and Mormonism, or more nebulous modern expressions of being spiritual but not religious or religious but not spiritual. How do we know what is true? Is one faith just as good as another?

Trial lawyer Mark Lanier presents the claims made by the world's great religions, discusses their histories, and cross-examines their witnesses (their scriptures and traditions) to determine whether their claims are worthy of belief. With his keen legal mind and methodical style, he provides a careful comparative study, highlighting key truths he finds in each religion even as he offers critiques. Treating each perspective on its own terms and weighing the worldviews for consistency and livability, Lanier assesses evidence for and against belief systems with criteria for what constitutes sufficient proof.

Believers and unbelievers alike will find here perceptive insights into how we can make sense of competing religious claims and what difference it makes for our own lives.
