The Atlantic has this survey of the history of carol singing, noting how the Puritans fought it.
My paternal great grandfathers both were associated with Presbyterian churches which had problems with music--organs being the trigger. I wonder whether that means their congregations still held against Christmas carols? I don't know--it's worth noting the best I can tell both men were on the pro-organ sides.
Anyhow, Merry Christmas and Happy Holidays.
