I was reminded in Mass to bid our sad divisions cease and to seek the God of Peace.  Maybe this year we should sing all verses of O Come O Come Emmanuel and meditate on the words.

Oh, come, Desire of nations, bind
In one the hearts of all mankind;
Oh, bid our sad divisions cease,
And be yourself our King of Peace.
Rejoice! Rejoice! Emmanuel
Shall come to you, O Israel!
