Our criteria include:
a) focus on the Christ Child and all His coming means;
b) whether it has stood the test of time (i.e. newer songs have the burden of proof; and
c) musical quality (though I realize many older hymns were later put to other tunes).
But first, honorable mentions include: Hallelujah! Chorus (I was recently told this was actually part of the Easter, not Christmas, portion of Handel’s Messiah); O Come All Ye Faithful, and Mary Did You Know?
The top five are:
5. What Child Is This? (I love the composer’s answer to his own question)
4. Away in a Manger (Children love this song and for good reason)
3. Silent Night (Is there any more serene song that this?)
2. O Holy Night (enough said)
