Well, we have been hearing about it from bishops, actual successors to the Apostles, and how can you argue with those guys, right? They say they've surveyed the Catholic faithful and they don't believe all this old fashioned sort of Catholicism. All that's out these days. Nowadays we believe in a less hierarchical church (see what I did there?) and more a democratic method of finding out what church is for.
It's not about "teachings"; it's about accompanying, about dialoguing and ...um journeying and...urrr... all that stuff... (bear with me, it will take a while for us Oldthinkers to learn to spew the idiotic lingo... to use the correct new vocabulary)...
Anyway, they've taken the survey and they've found out what they've been doing wrong all this time, and this Sensus Fidelium guy has suddenly popped up and said he wants the new, friendlier church of hugs.
And who, again, is qualified to change Catholic teaching? Only Almighty God. So, therefore, who is the Sensus Fidelium?
I think I need to write a letter to Cardinals Kasper and Muller right away, and tell them I've been inspired with a solution to the deadlock.
