Here's the thing. If you are honest, you'll have to admit that you have taken the following mental (logical) steps:

1. Here is the information (aka Biblical stories).
2. Here is what they mean.
3. I reject what they mean.
4. (I denigrate others supposed beliefs on the basis of 2.)

What you are rejecting is something your own particular version or interpretation of the information (biblical stories) creates, or posits.

On the other hand, others can well do the following:

1. Here is the information (aka Biblical stories).
2. Here is what they mean.
3. I accept what they mean.

Here, others will accept what they understand the information to mean, which is, most likely, very, very different from what you think they mean (which you reject). In other words, their number 2. is very different from your number 2.

See? Here, you've made the fatal mistake of accepting or asserting that your particular interpretation or understanding is orthodox, or correct, and on that basis, you denigrate others, whereas they are NOT accepting what you assert they are, but are in fact accepting something entirely different, something you've blinded yourself to through the myopia or arrogance of not recognizing YOUR role in the process (aka establishing point 2. by your choices and your interpretations) and your mental choices.

Don't fret it. It's a fatal flaw that many blunder into. Even those that do likewise, with other interpretations and views.

There is nothing wrong at all with having an interpretation, or accepting that the information means X. But when you fail to recognize that this is what you are doing, that you are a factor and an agent here, and you move on to the next step of criticizing or evaluating others based on that alone, you've missed the point.

No one else really thinks the information says what you are asserting it does, and consequently, pretty much no one else has the "childish beliefs" you set up to denigrate as a strawman argument that you use for bolstering your own egotistical and intellectual attachment to your own views.

If your purpose was NOT to bolster or shore up your own (rather tenuous) belief system, you would not feel compelled to make false assertions about what others believe.

But, you have done that. And, it's obvious to everyone else. If you can recognize that you've done this, you'll find a better way forward.

Have your beliefs, but you don't need to imagine or create false narratives about what others believe in order to justify it. If you do, it should be a clear sign that something else is driving you, something other than an open and secure search for truth.

When we examine the logical processes we choose to implement, aka our mental actions, these can very often been important markers that tell us something about what we are in fact pursuing, despite what we intellectually might tell ourselves.

Hey, have a nice day. No, really.
