How should I punish my stubborn and rebellious son?

My son is 16 years old and he has been acting rebellious lately. I've asked him to do his chores yet he refuses to do them. He's even been drinking Alcohol at parties. I read the bible a lot and I'm a very devoted Christian (I'm Catholic). So I get my morals from the bible. As a god-fearing man I'm scared because the bible says that I should stone my son to death for not obeying my commands in Deuteronomy 21:18-21. I'm really scared because I don't want to have to kill my son. I love God more than anyone else though so I try my best to follow his laws.
