Would you be offended?

I would simply ask that no presents be given to you. You can't make them by you secular stuff and they aren't going to buy you things that pertain to your beliefs....so the only thing to do is to ask that they buy you nothing.....or ask that they donate money, instead, to a cause that you both like....of course, they will probably try to find a christian version, but at least that saves you from having to find something to do with crosses and bibles.good luck!
