Ah, now I get it ... having seen your posts elsewhere, I was a bit puzzled by it.
It appears to be going in reverse over much of its former area, at least if we use moral standards and belief in Christ as the standard. Most of Europe is essentially post-Christian at this point.
True ... but does that stand as a refutation of the efficacy of Christian belief, or as confirmation of it?
Not sure what you mean.
I think Europe is in the end-stages of squandering its moral capital accumulated over centuries of Christian belief and will soon descend into the abyss. Possibly a Muslim one, but it will be some sort of atrocious end.
The US is fighting an epic, although so far more or less nonviolent, civil war right now to determine whether we follow them into the abyss.
