Just my 2¢: I'd suggest exposing your kids to a variety of religious traditions and worldviews, so they will understand that it's not just your word against the Bible study teachers' but myriad competing ideas. I think that would help any child understand that faith-based claims all hold similar weight, but evidence-based perspectives give us tangible reasons to accept them as valid.

What church do they attend? Was it similar to Bible Belt christianity (fundamentalism)? They believe the bible is inerrant. I think going to churches like this is harmful. There are other, more liberal churches that would explain that the stories in the bible are parables; they really didn't happen. I recommend Unitarian or Episcopal.

What does "redric" mean? I'm unfamiliar with that terminology.

Letting your kids go to bible studies because you are "able to debunk the redric [rhetoric] that is spewed" seems bonkers to me. While I appreciate that learning about different religions is a worthwhile exercise, I can't see what you're trying to help your children achieve here.

My siblings and I actually asked to go to church. It no doubt confirmed the atheistium we’d been brought up with, and, when ‘that question’ rounded the lunch table at school, “what church do you go to” … we finally had an answer!

I’d often ask my kids if they’d like to ‘check out a church,’ but after they’d quiz me on ‘what happens in there,’ they were no longer curious. I’d gotten some feedback from in laws once that my oldest had asked, “what do all the ‘little t’s’ mean on those buildings?” … and thought I’d better start explaining things to them

I’m impressed with what you’re doing, just stay close, and honest … and as far as the missing biblical text … good question

Hopefully, your kids won't be the target of hate from the teacher or the other kids. It happens all too often.
