"christian europe" as conservatives imagine it did not exist until charlemagne, and ended at the same time as the black death.
it's a few centuries.
a blip.
before that, you had a three-way struggle involving pagans & muslims ganging up on the empire (??), which emerged from the process victorious (when the pope crowned charlemagne emperor, he wasn't fucking around. this was the full return of the empire in complete intent and total scope. it didn't work out, but that was the plan.). europe wasn't simply delivered to german civilization as christian, or something. the germans were viciously anti-christian, and largely settled upon arianism (the idea that jesus was cool and stuff, but fully human) as a compromise with the new system moving up from the south. the late romans never fully converted themselves, either, maintaining things like diana worship in france (and there's evidence of pagan child sacrifice in italy after the year 1000, presumably to ask the gods for favour in the ongoing collapse of society).
so, the first meaningful christian empire in europe was with charlemagne, about the year 800 or so. they tried to change the calendar date and everything.
then, after charlemagne, they started launching crusades to convert people by force, initially mostly against white people. this provoked a retaliation against charlemagne by vikings, who set up in the north of france, and then in the south of italy, before becoming crusaders, themselves. there was something called the saxon genocide that occurred under charlemagne, where he slaughtered the entire saxon aristocracy for refusing to convert. crusades then moved east and north around the north sea, often literally via piracy, through the medium of the hanseatic league and the teutonic knights. berlin was founded roughly the year 1200 by crusaders taking over a slavic settlement, and they just kept going, not meaningfully reaching the baltic/slavic heartland until the year 1500 or so.
by then, the black death had already reshaped the ruling structures in europe, leading to the renaissance and then the reformation and eventually the true ethnogenesis that sunk in during the enlightenment, after all of the indigenous systems had been dismantled, and all of christianity's opponents had been slaughtered. if the idea of a christian europe ever existed at all, it was after the trauma of the black death that it began to fall apart, and not during these revolutionary changes, which came as a consequence of the rejection of christianity, and not vice versa. henry VIII was hardly at the start of a process, but at the end of one.
it is this struggle against latin and roman and christian colonialism that defines an emerging white identity, not the christianity itself, which tried to absorb them and control them and stamp them out.
