If you’re not supposed to believe the Bible literally then it shouldn’t be used at all imo. If you leave things open to interpretation, you literally create the circumstances for the incorrect beliefs that followers of that religion hold today. Because there most definitely are wrong interpretations and the majority of religious people are sheep that can’t think for themselves. That’s a very fragile system that is vulnerable to initiating horrible atrocities and suffering. And we literally see that in the world today. People killing each other over varying interpretations. Even within the same religion. Christians killing each other because they’re not catholic or whatever.
For example, let’s say a new sect of Christianity formed today based on someone’s new interpretation. And let’s say this new sect believes that it is essential to stop evil wherever it is seen. By any means. Well now you have a sect whose interpretation is that murdering all non believers is essential. Is that wrong? Of course. But you can’t tell them it’s wrong if the Bible isn’t supposed to be interpreted literally. And if the truth is that you’re supposed to be peaceful and not fight back (turn the other cheek and what not), then the sect will kill off everyone without any push back just because they disagree with their interprets. And this will go on until all that’s left is the believers of this new sect. And that’s how you end up in a world where everyone follows a religion with insane and nonsensical beliefs. An extreme example but it illustrates my point well.
