Major World Religions: a Complete Guide to the Beliefs, Histories, and Practices of the World's Great Faiths

Introduction

Religion is among the most enduring and universal dimensions of human experience. Across every continent, in every era of recorded history, and within virtually every culture that has ever existed, human beings have reached beyond the visible world to contemplate forces greater than themselves -- forces they have called by many names: God, the Tao, Dharma, the Sacred, the Divine. The impulse to seek meaning, to explain suffering, to mark the passages of birth and death and everything in between, and to live in right relationship with the cosmos and with one another has driven the creation of the world's great religious traditions, each one a vast inheritance of story, philosophy, ritual, law, music, architecture, and moral vision.

Today, the world's major religions collectively claim the allegiance of the overwhelming majority of the human race. Christianity counts approximately 2.4 billion adherents. Islam claims roughly 1.9 billion. Hinduism encompasses around 1.2 billion people, nearly all of them in South Asia or the Indian diaspora. Buddhism counts between 500 million and 600 million practitioners. Judaism, though far smaller in numbers at roughly 15 million, has exercised an influence on world civilization vastly disproportionate to its size. Sikhism, Taoism, Shinto, Zoroastrianism, and the indigenous spiritual traditions of Africa, the Americas, Australia, and Oceania add hundreds of millions more to the grand total of humanity's religious life. Taken together, faith of one form or another shapes the daily existence of more than eight in ten people alive today.

Yet religion is not merely a matter of statistics. It is the grammar of meaning through which human beings have organized their deepest intuitions about reality. It governs how people eat, how they dress, how they marry, how they grieve, how they govern, how they make art, and how they treat the stranger at the gate. Wars have been fought in religion's name; hospitals, universities, and libraries have been built in its honor. Philosophy, law, literature, music, and the visual arts have all been transformed by religious inspiration. To understand the world -- its history, its conflicts, its cultures, and its aspirations -- one must understand its religions.

This article offers a comprehensive survey of the world's major religious traditions: their origins, their core beliefs and practices, their internal diversity, their historical development, their sacred texts and holy sites, and their ongoing significance in the modern world. It begins with Hinduism, the world's oldest living religion, and moves through Judaism, Buddhism, Christianity, and Islam before turning to Sikhism, Taoism, Confucianism, Shinto, Zoroastrianism, indigenous traditions, and new religious movements. It concludes with reflections on the common themes and global impact of religion as a human phenomenon. The goal is not advocacy for any faith but illumination of all of them -- an invitation to understand the spiritual heritage of humanity in its breathtaking breadth and depth.

Hinduism: the World's Oldest Living Religion

Hinduism is not so much a single religion as a vast family of related traditions, philosophies, and practices that have developed continuously on the Indian subcontinent for at least four thousand years, and possibly much longer. It has no single founder, no single authoritative creed, no single governing body, and no moment of origin that historians can point to with confidence. It is a living river fed by countless tributaries -- Vedic ritualism, Upanishadic philosophy, devotional bhakti movements, tantric practice, yogic discipline, and the folk traditions of hundreds of distinct regional and caste communities. Yet for all its diversity, Hinduism possesses a recognizable core of shared texts, concepts, deities, and values that justify treating it as a coherent tradition.
