The podcast From Israelite to Jew studies the cultural development in Judaism from a historical perspective. As explained by the beginning of the series, around the 6th century BCE there were Israelites that adhered to Judaism. Israelites were a rather loose federation of tribes. Over time they developed into an ethnicity called the Jews.
When speaking of THE Jews, the impression may arise that there is some kind of unity and there is one Judaism. The podcast's host, Michael Satlow, turns to what little sources there are and attempts to measure that unity. For one there are the Hebrew bible and apocryphal Hebrew sources, which mostly concentrate on the worship around the Temple in Jerusalem. In addition there are Greek and Latin sources that paint a radically different picture of assimilated Jewry, but does this mean there are these two, the real Judaism and the watered down, bound to disappear Hellenistic Judaism?
Satlow proposes a different idea, one that breaks away from the dichotomy of observant and assimilated Jews. There had been Jewish communities throughout the Greek Empires ever since the second Temple Period (500 BCE - 70 CE) started. if you look at the Temple cult in Jerusalem, the alleged pure Judaism, it would have been impossible for Jews in faraway places to maintain this kind of Judaism. However, this does not necessarily mean, that all these Jews assimilated to disappearance. Satlow suggests a wide variety of ways these Jews must have maintained and developed their Judaism. This is where the shift from Temple to Synagogue may have started, way in advance of the destruction of the Temple and the last diaspora. Satlow's history is a history of a Judaism that is in continuous development driven by many Jewish varieties.
