Was DS9 trying too hard to draw a parallel between the Bajoran religion and the bible?
Satan is present in all the Abrahamic religions, and not just the Christian. Demons too, although they appear in other beliefs in different forms. The parallels between the polytheistic Bajorian beliefs and the Bible are pretty thin.
Plus unlike the problems with reinterpreting static texts and doctrines brand new stuff can happen at any time thanks to the orbs
One of the tenets of the Bajorian faith might be the process of constant revelations. They simply accept that information is going to be trickling in over time. Thousands of years. it's all part of the whole.
