Yes, from December 21st onward there is supposed to be strict fasting (you just reminded me that I'd read this also). The OCA is heavily Slavic, as many of us are probably aware, which is likely why the book I read doesn't prescribe fish for a lot of days at the beginning of the fast period. And I hope that you find the Church's version of the Feast of the Nativity to be the way that it would best be experienced by all believers.
Well, I still have to have some modifications, but I am very thankful to my SF. He was able to give me guidelines such that I shouldn't have to worry from a medical standpoint, yet it is not "easy" for me. Up till now I haven't had something that so suited me.
I'm trying to ignore billboards and TV commercials and everything else that comes in visually to be tempting ...
What I really do appreciate is the kind of flip-flop of attitude. I'm sure many of us are familiar with the "Christmas season" at least from a modern American standpoint. I always tried to have a rather low-key season and focus on the birth of Christ in as many ways as I could, but it was still a rather indulgent, celebratory season, culminating in Christmas Day. While my own household never worked this way, I have shared the holiday with my sister, and they typically unwrapped gifts on Christmas Eve (that was the highlight once there was a new generation of children) and there would be a feast dinner on either Christmas Eve or, at latest, Christmas Day lunch. The tree was usually on the curb by Christmas evening, and all reference to the holiday purged.
What I see now is the reverse in many ways. Instead of being indulgent, we are fasting. Instead of celebrating, there is a penitential atmosphere, everyone is encouraged to come to confession, examine ourselves, pray more, cleanse ourselves to be a more fitting reception for our coming Lord. There is a sense of anticipation, not for gifts, but for the birth of Christ. Christmas Day (His Nativity) is not the ceasing of all celebration, but the cause to begin it. It all seems SO MUCH more fitting.
(Ironic, because last year I got my tree finished on Christmas Eve/Day, iirc - and this year I do plan to put it up earlier for the sake of others, in spite of this new way of looking at things. And I'll probably play and sing Christmas carols during "the season" for the same reason - but I plan to keep them after as well, for me.)
Anyway, that's what I'm suddenly aware of, that was really lost on me last year after my baptism, since I was traveling so much and so newly Orthodox.
