How do religious beliefs influence culture?

There's an old
saying that "culture is religion externalized." This is a simple way of saying that by
looking at the culture a society creates and consumes, a person can discern, in general, that
society's basic beliefs and worldview. "Worldview" refers to the major philosophical
questions of life which influence our outlook on life, such as: Does life have meaning?, Is
there a god and is he/she/it involved with the world or separate from it?, What responsibility,
if any, do I have to other human beings?, etc.

As Christian philosopher R.J.
Rushdoony explains:

Every culture is a
religion...
