Yes, the secularization of the Candlelight Procession has indeed been reversed.
The vocals no longer begin with "The Most Wonderful Time of the Year" which is all about partying for that "Time of Year" and mentions Christmas only in the line:
And tales of the glories of Christmases long, long ago.
It's the kind of non-Christmas Christmas-song parodied/mocked by Olaf in "That Time of Year" which mentions all the associated Christmas traditions without mentioning Christmas (except for a quick Mele Kaliki).
It was totally out of place for a concert in which Sacred Song and scriptural quoting is professing the Christian faith that Jesus is God incarnate and thus, savior for all from sin and death.
"Let There Be Peace on Earth" is also gone.. and good riddance. They used the second verse only of the song which doesn't mention God or anything religious.
The overly saccharine introduction to Silent Night has been shortened -- Altho, why they don't continue to use biblical passages is beyond me. Who there thinks that whatever treacle they write is more appropriate?
Also, they added and overly saccharine introduction to "Joy to the World" in which, after all these songs and scripture verses proclaiming Jesus to be Messiah and Savior, they go on about "what a nice guy he was." <roll eyes>. This also includes Biblical hallucinations about Jesus sharing food off his place and giving drink to those who were hungry and thirsty. A complete misremembering of the Multiplication of the Loaves and the Last Supper. They need to upgrade to a more recent AI to write their copy.
Anyhoo, "Joy to the Word" and the "Hallelujah Chorus" are now each their own complete song and seemingly much more well received by the audience than that Frankenmashup of the past which confused everyone about whether they should stand for the Hallelujah parts (and you should stand as a member of Western Civilization).
Though, as a continued poke in the eye, "Jingle Bells" in the instrumental overture has been expanded from a quick wink to it's own full song. So out of place. So stupid.
But, far be it from me to say anything critical about what Modern Disney does.
