The Bible should be allowed in schools, as major religious texts from all religions should be. But directly teaching them isn’t exactly the correct way to go about things, unless there is a class specifically studying religious applications and the student opted into taking that elective and it wasn’t forced upon them.
Biblical allegories are literally everywhere. So having the background lets you grasp and further understand the themes being presented in many corners of literature. And that is of course a consequence of America having such a large religious population that uses the Bible. To successfully do this, the Bible would need to be taught in a similar way that schools teach mythology. As stories and not as worship
So I think using a biblical story as a teaching opportunity in an English class would be fine, I think the actual population that is fighting for the Bible to be taught in schools would be angry about it being taught in an objective way rather than the indoctrination-into-worship they want it to be taught
I think other religious texts should be taught too. And a good opportunity for that would be in conjunction with literature or media that references it. For example, maybe you’re watching a film from Japan, per se. And you see temples and statues and references to spirits and legends in this film. Studying those religious and mythological influences would provide a deeper understanding of the films influences, but also let you identify it in other media as well
Crude example, but Naruto. Naruto prominently and consistently featured a reference to the Nine Tailed Fox. It indirectly brought a piece of Japanese culture into American homes in the early 2000s. And curious kids naturally went to look up the Nine Tailed Fox and went down the rabbit hole of its origin. And now they’re able to catch the reference in other media and literature as an adult.
