Religionists worry and debate about “how” or “if” their religion should change — it is a universal phenomena. Very similar to languages, religions change whether people want them to or not. Here is how I imagine the various voices debating the issue of change:
The Conservative Religionist: Truth must be preserved. Our faith must hold steady and not change.
Liberal Religionist: God speaks and works differently at different times. We must adapt our message and expression as culture changes.
Anti-Religion Atheist: It is all hogwash, who cares.
Anthropologist/Psychologist: Religion is a personal/cultural tool. It changes to reinforce or initiate a change in person/culture and has very little to do with actual truth. It is the deep structure of religion (relationships, actions, attitudes) that effects a person/culture, not any inherent “truth of dogma”.
No matter how “right” or “wrong” these attitudes are, all four will interact in the evolution of religion — all will count!
