Hi dear Thunderbear ~ Religious fanatics are some of the most DANGEROUS people! They can cause more damage in children and even adults than people who have no belief system at all.
Your family is obviously of that nature and they are TOXIC to you! In order for you to protect your mental health, you need to stay away from them, avoid ALL contact with them, and "unfriend" them on Facebook or else drop Facebook altogether!
If you do happen to hear something, just take it with a grain of salt -- don't believe it, and in fact try NOT to even listen to it in the first place. Whoever tries to tell you things about them, tell them you just aren't interested.

It's best for your own mental health.
I'm sorry you have to put up with this kind of thing, but you aren't alone. There are alot of folks who are going thru similar stuff -- it's tough! Best of luck and take care. Remember -- you come first! God bless. Hugs, Lee
