The religions of the world that existed prior to Doomsday remained so in the nearly three decades after the event. Only in the largest and most advanced nations are several religious faiths still practiced. In much of the world's surviving nations, one religion predominates, with others existing as smaller religious minorities. This is a brief snapshot of the current major world religions, and where their adherents are most likely to be found:

Christianity is practiced not as a single orthodox religion, but in four distinct subgroups with common roots: Roman Catholicism, Protestantism (itself subdivided into numerous forms), Eastern Orthodoxy, and Oriental Orthodoxy.

Judaism is practiced primarily by the Jewish people, an ethnic group found primarily in Israel, but also found scattered throughout the globe.

Islam is practiced primarily in the Middle East, northern Africa and south Asia; groups can also be found throughout central and southern Africa, Oceania, Europe, and in North America.

Mormonism is practiced in the Commonwealth of Deseret and in pockets scattered across the world.

Jehovah's Witnesses are scattered across the globe; stagnant.

Hinduism remains the predominant religion of former India and the areas around it.

Buddhism is also found in India and East Asia.

Sikhism continues in former India.

Jainism continues in former India; stagnant.

Folk religions such as Shamanism and Voodoo exist across the globe.

Humanism has recently come into vogue among certain intellectuals in the ANZC, Europe and South America.

Paganism is found in parts of the former United Kingdom, especially in the areas surrounding Stonehenge.

Many new religious sects have arisen in the post-Doomsday world, including:

Lincolnism (the belief of former US President Abraham Lincoln as a deity) in the US survivor Republic of Lincoln.

Cult of the Once and Future King (an outright deification of the British Monarchy itself) in Southern Africa.
