Start with three things you can do today

Type this when Cadence asks what you want to learn

I want to understand the world's major religions, what people actually believe and practise, and how they differ. I live and work alongside people of many faiths and I do not want to rely on stereotypes or say something ignorant.

Change any word so it fits your situation. The course is built from what you type and a few setup questions.

Start today

Four things you can do before the course exists.

Useful on their own. The course is for when you want the whole skill, not just the first move.

  1. Learn the rough sizes

    Pew Research Center estimates that in 2020 about 28.8% of the world's population was Christian, 25.6% Muslim, 24.2% religiously unaffiliated, 14.9% Hindu and 4.1% Buddhist, with Jews about 0.2%. Size says nothing about importance, but it corrects common guesses.

  2. Compare traditions with the same five questions

    For any tradition, ask: what do followers believe about the divine or ultimate reality, what do they practise, which texts matter, how is community organised, and what are the main branches? Filling the same grid for two faiths shows real differences and overlaps.

  3. Separate texts from lived practice

    What a scripture says and what a particular community does can differ, and practice varies by country and family. When you read 'Hindus believe' or 'Christians do', ask which branch, where, and according to whom.

  4. Ask about a person's practice, not their whole religion

    Instead of 'What does Islam say about this?', try 'Is there anything about how you observe Ramadan that would help me when planning team lunches?' It asks about their own practice and lets them share only what they want.

Before the course is built

Setup asks about your situation first.

Lesson 1 opens on the moment you describe, and the examples use your role. For this request, expect questions like these.

  1. Which traditions are you most curious about, and why?
  2. Do you have a faith background of your own, or none?
  3. Is this for work, friendships, travel, or general understanding?

Right for now

If any of this sounds familiar, start here.

You work alongside many faiths

And want to understand colleagues without awkward guesses.

You were never taught this

Religious education at school was thin or one-sided.

The news uses religion as shorthand

You want to know what the labels actually mean.

Course arc

Where the course goes, in order.

Cadence writes the lessons for you, so the exact path follows your answers. This is the ground a course built from this sentence covers.

01 / 06

How to compare religions

Beliefs, practices, texts, community and experience as lenses.

Abrahamic traditions

Judaism, Christianity and Islam, their shared roots and their differences.

Traditions from South Asia

Hinduism, Buddhism, Jainism and Sikhism, and how they relate.

Traditions from East Asia

Confucian, Daoist and Shinto traditions and how they often blend in practice.

Variety within each faith

Branches, local customs and individual belief.

Faith in daily life

Festivals, food, prayer and how to be a considerate colleague or neighbour.

What changes

What you will be able to do, and what you will stop believing.

You will be able to

Describe each tradition fairly

Summarise core beliefs and practices in terms followers would recognise.

See the variety within

Know that each faith has branches and people who practise it differently.

Ask respectfully

Talk about faith with curiosity rather than assumption.

Ideas this course corrects

Every follower of a religion believes the same things

Each major religion has many branches and a wide range of individual belief and practice. Ask rather than assume.

Most people in the world are not religious

Pew Research Center estimates that about three quarters of the world's people identified with a religion in 2020, though the unaffiliated share is large in some countries.

Course questions

What to know before you start.

Major world religions explained: what can I do today?

Learn the rough sizes. Pew Research Center estimates that in 2020 about 28.8% of the world's population was Christian, 25.6% Muslim, 24.2% religiously unaffiliated, 14.9% Hindu and 4.1% Buddhist, with Jews about 0.2%.
