I think that you can talk to your kid about how different people believe different things and share your beliefs with him and tell him that you disagree with his grandmother. I don't think it is about 'unbrainwashing' him as it is about encouraging him to think for himself.

after spending some time with my aunt my daughter has said some things about god and jesus that I found uncomfortable. I agree with adcaela though, the best you can do is just explain that you believe something different. many of the kids she goes to school with are christian and she's asked me if we are too. i explained that i'm not, but that she's free to make that decision for herself.

I dont know if its soo much "un-brainwashing" him, that it is teaching him about other religions, and the need to respect and understand that someones religious choice is a personal one. Everyone should be free to make their own spiritual choices---I guess it is just a matter of making sure it WAS a choice, and not a desicion that was made for him.
I remember when I was really young--around that age--- being brought up by a parent who was an atheist. I was pretty much given the choice to choose whatever religion that I wanted to. I had some hard core christian friends who would bring me to bible school and all that....I kinda go into it for a while, but now that I am older, I grew out of it.

I live with my parents so there is no way getting around it, my parents are christian so eric knows about some of the stories and what not that I don't really believe as the truth. But I just try to do what other said, tell him that some people believe different things and since Ethan is a little bit older maybe you could even teach him about other religions if you feel comfortable. Also since he was saying that you don't like jesus maybe you could say whatever you feel ok with, like I would say if it were me that I just believe that jesus was a man and not the son of god, or if you want to say that you think they are just stories or whatever. I just think what is most important is to let them make their own decisions and let them know that whatever they choose to believe is ok.

I agree with other posters. I think it could also be helpful for you to share your religious beliefs (whatever they may be) so that he's presented with another option.

riley wants to go to church, so i let her, she knows my beliefs and i know hers. there is no way i will push my own beliefs on her in that instance.

Thanks for the advice everyone. I'm in Las Vegas right now, but we're going home (to California) on Sunday night. I've spoken to him about how other people have different beliefs and that I don't believe that jesus was the son of god, but that he was a person. I plan on talking to him more about it sometime next week (when we're away from the other influences here) and take him to barnes and noble and reading to him about different religions (I remember them having a couple of good kids books to teach kids about various religions when I was working there). Thanks again, for the advice.
