Terminology: Religion

These are the definitions that I’ve seen people actually applying to the word Religion possibly depending on convenience.

1. Refers to Christianity alone

2. Refers to all the world’s religions

3. Refers to all the world’s religions except Atheism (possibly because they want to look neutral.)

4. Refers to all the world’s religions except Christianity (like in laws where free speech and religions are protected unless Jesus is mentioned)

5. Worldview

6. The rules an individual uses to define how the world works.

Can you think of more ways … contradictory or not based on how the word religion is used what other meanings it has picked up?
