So, I know that the Protestant Reformation has its heart in the northern half of Europe, what with Martin Luther and Henry VIII and the cultural differences between the two halves of Western Christendom. And I know that the Papacy's main base being in the southern half of Europe and its distance from the northern part makes this difficult.
But I was wondering what it would take for Britain and the northern Germans to remain loyal to the Pope while Spain and Italy start a schism in the Church. And what such a thing would mean for Europe as a whole.
