My point was that the whole period, starting with Augustine, was about Christianising the previous philosophy and government. The Greeks had well developed morality but universalism was not really a part, even the Romans firmly split between citizens and non-citizens, patricians and plebs. Greek philosophy is heavily responsible for the misogynistic aspects of Christianity for instance, but during this period women had more legal freedoms and ability to exist independently and their rights actually became worse later on.
Everyone is influenced by what came before, but we very much live in a world in which their developments on previous philosophy are very welcome.

Any references for this? I find it highly doubtful.
The Greek philosophy was universal in that it applied to anyone who was a "person". I don't think that's different from any morality that's followed, it's just that the "universe" has always been limited, e.g., in U.S. rights were created universally for "all men", but that didn't originally include women or slaves.
