I grew up in the Lutheran Church. When I was very young, it was the Danish Lutheran Church, although my parents weren't Danish (the people there were very nice, and they had the best coffee!). Over the years, the church attracted Lutherans from many northern European countries, and I had the great good fortune to make friends with Danes, Estonians, Germans, Swedes, Norwegians, and others.
On Christmas Eve, we had our candlelight celebration, and the last song of the service was always Silent Night. With the main lights out and each person holding a small lit candle, all would sing the carol in their own language.
I always loved to hear all those voices and lyrics around me. It was an emotional time for many, as they remembered, I'm sure, past Christmases with their families in their homelands. There was always a tear or two.
Silent Night in German (it's original language)
In English, and in keeping with those childhood Christmas Eves in the Lutheran church, this choir is from Peace Lutheran (from where, I don't know).
I would love to find a video of Silent Night sung in all of these languages all at once, but I'm sure none exists. But whenever I have attended a candlelight service in years since, they usually end with Silent Night, and then I hear them all in my heart.
