I would honestly, try and seek custody of my child and tell the judge the woman is a lunatic.
Ask him if he has ever heard of Ed gein,. and tell him this woman is drilling christ into his head like that, and you fear for his afety.
Bring up this lady:

she killed her kids because God Told her To!
tell the judge you fear your ex wife is some jesus sicko and get your child away from her, while you still can.
i would NOT allow this to go on if it was my child.
no way.
