I was raised as an evangelical Protestant.  Christmas hymns sounded like this:

O little town of Bethlehem
How still we see Thee lie
Above Thy deep and dreamless sleep
The silent stars go by

Yet in thy dark streets shineth
The everlasting light
The hopes and fears of all the years
Are met in Thee tonight

For Christ is born of Mary
And, gathered all above
While mortals sleep, the angels keep
Their watch of wondering love

It’s beautiful, peaceful, perhaps a little plaintive.  Compare it with the following short hymn chanted on Christmas Eve in the Orthodox Church:

Hear, O heavens, and listen, O earth. Let the foundations be shaken, and let trembling seize the netherworld. For God the Creator has entered the physical world; He who created creation with His mighty hand is a fetus of His own creature. O the depth of the riches of the wisdom and knowledge of God! How inscrutable are His judgements, how unsearchable His ways!

The incarnation of the Creator of all was a silent affair, kept hidden from the powers of this world, both secular and demonic.  However, it was an event of cosmic significance. Of course I’m only comparing two hymns, but I really think that Orthodox hymnography conveys the stupendous, monumental, earth-shaking import of Christ’s birth somewhat better.

Christ is born! Glorify Him!
