Turkey, OCA, and Other Feasts

Every once in a while, especially on holidays like Thanksgiving, I wonder what other feasts are out there and celebrated on this day. The OCA web site is usually an excellent place to begin. I'd love to learn more of the significance of this feast and its place in the worship and theological life of the orthodox church. For now, I'll just remember the blessed Mary today in addition to the blessings of God's care for us. The Small Catechism is as good a place as any to be reminded what Christians give thanks for on this day:

I believe that God has made me and all creatures; that He has given me my body and soul, eyes, ears, and all my limbs, my reason, and all my senses, and still preserves them; in addition thereto, clothing and shoes, meat and drink, house and homestead, wife and children, fields, cattle, and all my goods; that He provides me richly and daily with all that I need to support this body and life, protects me from all danger, and guards me and preserves me from all evil; and all this out of pure, fatherly, divine goodness and mercy, without any merit or worthiness in me; for all which I owe it to Him to thank, praise, serve, and obey Him. This is most certainly true
