In truth, European civilisation is anything Europeans make of it, just as Christianity is anything Christians make of it, Islam is anything Muslims make of it, and Judaism is anything Jews make of it. And they have made of it remarkably different things over the centuries. Human groups are defined more by the changes they undergo than by any continuity, but they nevertheless manage to create for themselves ancient identities thanks to their storytelling skills. No matter what revolutions they experience, they can usually weave old and new into a single yarn.
