could anyone briefly summarise why Christianity was a problem for Epicurus
Early Christians could not reconcile the two traditions, and Roman Epicureanism was an ideological competitor to Christian evangelism. "Also some Epicurean and Stoic philosophers debated with him. Some said, 'What does this pretentious babbler want to say?' Others said, 'He seems to be a proclaimer of foreign divinities.' (This was because he was telling the good news about Jesus and the resurrection.)" (Acts 17:18 NRSVUE). Whereas elements of Stoicism were incorporated into Christian theology (Providence, a Universal God, etc.), Epicureanism is antithetical to Christianity.
