That is an awkward position to be in! Whatever the reasons for your family not going to Church, keep Sundays holy! If you can get a ride with a friend, classmate or neighbor that you and your family trust, perhaps that is the way. One day you might be in walking distance to get to Church or have a drivers license to be able to borrow the family car and drive there. Around Christmas time, children have a way of hounding their parents for all sorts of gifts. Have you ever considered asking persistently, but not in a nagging way, to go to Mass?
