Best Books on Religion & Spirituality

The World's Religions by Huston Smith is the standard recommendation for this question, having introduced millions of readers to Hinduism, Buddhism, Confucianism, Taoism, Islam, Judaism, and Christianity with genuine care for each tradition. Smith was not neutral in the sense of having no views, he believed religion matters and wrote accordingly, but he presented each tradition on its own terms. Karen Armstrong's A History of God is a complementary read focused specifically on the three Abrahamic religions and how the concept of God evolved over time.

Diarmaid MacCulloch's Christianity: The First Three Thousand Years is the most comprehensive single-volume account in print, at about 1,100 pages. For a shorter version focused on the Reformation specifically, MacCulloch's A History of the Reformation is under 750 pages and covers the period that shaped modern Western Christianity most directly. For early Christianity (the first few centuries), Bart Ehrman's Lost Christianities explains how much diversity existed before the church settled on a single orthodoxy.

No god but God by Reza Aslan is the most widely read Western-audience introduction to Islam's history, from Muhammad's life through the major theological schools and modern political Islam. Karen Armstrong's Muhammad is a sympathetic biography that focuses on the prophet's historical context. For the Quran itself, M.A.S. Abdel Haleem's Oxford World's Classics translation is considered the most readable modern English version by specialists.

What the Buddha Taught by Walpola Rahula is the most concise, clear introduction to early Buddhist teachings, written by a Sri Lankan monk for Western readers. It covers the Four Noble Truths and the Eightfold Path without esoteric jargon. For a more narrative and personal approach, Thich Nhat Hanh's The Heart of the Buddha's Teaching is gentle and practical. If you want to understand Zen specifically, Shunryu Suzuki's Zen Mind, Beginner's Mind is the most widely read introduction.

Leaving the Witness by Amber Scorah (about leaving the Jehovah's Witnesses) and Educated by Tara Westover (about escaping a fundamentalist survivalist upbringing) are the most-read memoirs in this category. For a more philosophical engagement with the question of belief, Faith After Doubt by Brian McLaren argues that doubt is a necessary stage of mature faith rather than its enemy. Richard Dawkins's The God Delusion represents the complete rejection view, clearly argued and worth reading regardless of where you land.

Who Wrote the Bible? by Richard Elliott Friedman is the best accessible account of the documentary hypothesis (the scholarly view that the Pentateuch was compiled from multiple distinct sources). Bart Ehrman's Misquoting Jesus covers how the New Testament texts were copied, changed, and shaped over centuries. Both books are written for general readers, require no seminary training, and will permanently change how you read scripture regardless of your beliefs about it.
