The Chrismologist's Advent Calendar - Day 25

Now I know that Advent Calendars don't usually include Christmas Day itself (I'm talking traditional Advent Calendars here, not the mass produced, branded, chocolate disgorging monstrosities) but I'm the Chrismologist and I bring you tidings of great joy! So, with that in mind...

Merry Christmas!

Yes, Christmas Day is here at last, and hopefully some of you are waking up this morning to find that Father Christmas has left you a copy of What is Myrrh Anyway? or Christmas Miscellany in your stocking!

I hope you all have a wonderful day, no matter where you are or what you're doing.

So we keep the olden greeting
With its meaning deep and true,
And wish a merrie Christmas
And a happy New Year to you.

(Old English saying)
