I've' stated it before, my parish is Old Calendar, personally I have preference for the New, but no real passion one way or the other as there are strong points in defense of each. If it changes some day, so be it, if not so be it...This past year I celebrated the full cycle of the Nativity week on the New at my son's parish in Georgia. It FELT in my heart like Christmas to the extent when my wife said to me after Liturgy on the 26th of December that we HAD to get to the mall for the sales...I groggily replied...there won't be anything left by now..you always do that on the 26th....
That being said, I don't think either the New or Old calendar Orthodox really use this issue as the basis for 'anathemas' or 'schism', I see it as an excuse used by both sides where there may be deeper issues under the surface. Surely on the face of the earth, given current events in particular, the calendar by itself - one way or the other - is a rather poor, if not (to use the vernacular) crappy excuse over which to divide the Church....
