From our parish newsletter:
AMERICAN THANKSGIVING DAY- On the Fourth Thursday of November, the people of the United States gather in their families to thank the Lord for all that He has done for us, and for our world. Many Orthodox Parishes serve the American Thanksgiving Service written By St. Tikon when he was a bishop in the United States. The Holy Synod of Bishops of the Self-Ruling Archdiocese of The Antiochian Orthodox Church of North America has granted to Antiochian Orthodox Christians the oeconomia of eating a traditional Thanksgiving Feast including Turkey on this day despite it being in the Nativity Lenten fast period. Your non-fasting recipes that have leftovers will need to be packaged and frozen awaiting the feast of the Nativity to finish enjoying them.
