And for those of you who cheat...admit it. Don't be shy
I know some Greeks who do...lol
My priest (GOA) told me that the church gives its blessing to break the fast for Thanksgiving. I have have no idea what the practice of other jurisdictions in the US is.
Look at this: http://www.goarch.org/en/news/NewsDetail.asp?id=1887
Especially the last paragraph:
It is my heartfelt prayer that as we come together on this Day of Thanksgiving, feasting in thanks and in gratitude with our loved ones, friends, and family, we may be cognizant of the very special blessings that we enjoy in this land and that we may strive in our daily actions to reflect that gratitude in the love we show to others.
I certainly hope feasting doesn't mean a soy turkey!
