What does Christmas mean to you? Did it start with shopping on Black Friday, or Cyber Monday, or even sooner? Are there long lists of gifts to buy? Does this season involve spending lots of time putting up Christmas decorations? Is there a stream of holiday parties to attend? Do you send many greeting cards, either by postal service or email or both? Christmas means many or all of the above for most of us. But the most important question about the meaning of Christmas is this: Will you attend Mass on Christmas? Because that is the essence of Christmas: Christ’s Mass.
