“What did (What would) Aristotle say (have said) about christianity?:
Really great question. He lived before the existence of Christianity so this is speculative response but I’m pretty sure I’m right… He would have hated Christianity for oppressing Hellenism and especially philosophy.
Many assume ancient Greeks were all pagans. Most were but some were atheists or believed in various other deities not typically associated with ancient Greek god pantheon (especially during the Hellenistic period when Greek culture fused with other cultures )
In Aristotle’s case there is no indication that he believed in Zeus, Apollo, et all.. He sometimes wrote about paradoxes in reason where he would bring up god. Perhaps his most influential and famous question was ὃ οὐ κινούμενον κινεῖ.. the unmoved mover.. which is sometimes called the problem of infinite regress or prime mover problem. The paradox goes if everything had a cause then what was the initial cause to get everything going? And he inserted god as the answer. It is unclear if he meant this as a reasoning exercise or really believed in some supernatural god.
Early Christians’ long after Aristotle’s death adopted some of his ideas and integrated them into Christianity theological teachings. . Back then then though Christians were such fanatics that make the Taliban today look like liberals. Once the (Latin) Roman empire officially converted to Christianity, Christians start persecuting pagans (including ancient Greeks until they all converted. This is when the term “Hellene” (Greek) fell out of flavor and Greeks start referring themselves as Romans (which others call “Byzantines’ today to avoid confusion with the various other Roman states)
Eventually the Roman empire split into two. One mostly German speaking one originally lead by Charlemagne. And another’s mostly Greek speaking one originally lead by Irene the Athenian. When the Ottoman empire wiped out the last remnants of the eastern Roman empire in the 15th century, tbecame the RUM millet (Turkish for “Roman”)
When modern Greece was formed there was a lot of philhellenism due to great admiration of ancient Greece. I think philhellenes expected to find a new Aristotle building another Parthenon but mostly found Greek speaking Christian peasants more interested in Jesus than Socrates.
To what extent we are related to ancient Greeks is a controversial issue to this day. Greek haters all patronizingly claim its a “myth” we are related ancient Greeks (Turks and former Yugoslavians especially like to push this narrative). The current balance cultural, linguistic and genetic evidence on the other hand all suggest we are direct descendants of ancient Greeks but with admixture.
