Now a word for priests, MCs, liturgy committees, and anyone else interested.
Christmas liturgy should be unashamedly theatrical. Candlelight is a must for a dramatic Midnight Mass. A young child singing a soprano solo will eliminate any Grinch-like tendencies amongst Scrooge-ist parishioners. Perhaps more importantly, the involvement of a school or youth choir will bring in parents and relatives, giving the Church a chance to speak to those who mightn't usually turn up on the average Sunday morning.
So this is just a friendly reminder. Christmas is something that sticks in people's minds. Perhaps, years from now, a fallen away Christian will remember Father Whatsisname's Midnight Mass '08, the way the choir sang, the deep music of a pipe organ, an eloquent homily... it will all come flooding back, and the spiritual life of such a person will re-awaken.
Don't waste Christmas.
