What does Okonkwo say to his sons and daughters after Nwoye leaves the family for Christianity?

Okonkwo disowns Nwoye after he joins the Christians, claiming Nwoye is no longer his son, no longer his children's brother. Okonkwo tells his children, "You have all seen the abomination of your brother." He also tells them that if they wish to convert, they should do it while he is alive so that he can curse them. If they convert after he is dead, his dead spirit will rise up to kill them.
