I'll be the first one to contest the idea that modern civilization came out of a creative tension between Athens and Jerusalem. ((What tension???))
If you read in the book of Maccabees you'll see that Antioch Epephanes tried very hard to force Hellenism on the Jewish people, which led to a rebellion. You have Hellenism and Judaism which have throughout history either been in conflict or competition with each other. Then you have the synthesis of Hellenistic Judaism which conservative Judaism was critical of.
