Ready for a fun Supposition?
Here’s something to consider–it’s for fun you do not need to agree with me, but I like it and will continue to believe it.
It Came Upon A Midnight Clear is an Advent Song.
1. It’s about angels
2. It’s about their endless song
3. This entire verse is advent And ye, beneath life’s crushing load, Whose forms are bending low, Who toll along the climbing way With painful steps and slowLook now! for glad and golden hour Come swiftly on the wing;O rest beside the weary road, and hear the angels sing.(Waiting, pentitance, getting through ALL advent themes)
4. Verse 4 is all about prophecy….as is the whole thing
Anyway we sing Christmas song early anyway but we almost always sing it the 2nd week, for peace as an advent prophecy song, because I maintain its been misfiled

I had to laugh when I read this because for the 20 years I’ve been ordained the struggle of singing Christmas hymns during Advent has been real. Then an Epiphany…we are singing the verses of these songs that are less familiar and avoiding the verses about the birth already occurring. Singing the less familiar verses makes them much more Adventy. Can’t believe it took me 20 years to figure this out! So, I totally agree with you and we will be singing this carol this Sunday as well.
