So you can’t have a separate account for your religious or political work?
A Facebook account is based on a “real person” ... you can’t create a “fake person” in order to have another account.
You can create a “Page” however (but not a new account) and that “Page” can deal with different subjects.
You will still be only “one account” and “one real person” ... even if you create different “Pages” for different areas.
