From Where Such Sound?

In the Bleak Midwinter, Stille Nacht, God Rest Ye Merry Gentlemen, Hark the Herald Angels Sing, Adeste Fideles, Handel's Messiah, Veni, Veni Emanuel, Gaudete! Gaudete! Christus est natus... Is such music an accident, a composer's misguided belief in the Creator's invasion of history? Can such sound exist in the world apart from a Grand Composer? Is such music merely the product of deluded men who plunked the harpsichord without any transcendent tablature whispered in their ears?
