I am counting you CMAA folk among my blessings, too.

I’ve never thought of Thanksgiving Day as a secular holiday. “Thanksgiving” necessitates a person to whom one is expressing thanks (so obvious that the seculars needed to change the name, even to something as dumb as 'turkey day', to escape the obligation- not that one could ever escape it).

We, on the other hand, know thanks to be a happy obligation
Gratias agamus Domino Deo nostro.
Dignum et justum est.
