Son's Bio dad question?

I think it's good that he wants to be a part of your son's life but it's wrong of him to come in and start ordering you on how to raise him and what schools and church and such to send him to. I would tell the dad that he has been doing great in the school and church he is and doesn't to change. Also, I would tell him that the kid was just fine for the first 10 years when he wasn't around and you don't need him butting in. If he doesn't like it he can stop seeing the kid, the kid was doing well without him.
