What was Christianitys impact on philosophy?
They are kind of inter-related. Ancient Greek philosophy gave the early Christians the vocabulary to describe the experience of Christianity; and Christianity gave Philosophy some ideas it hadn’t thought of before. For example, the Christological controversies in the first few centuries (i.e. the arguing about how could Jesus be both God and Man) allowed philosophers to better conceptualize what “having personhood” and “having human nature” meant.
