At the same time that Jews were confronting the cultural differences at their door, they had to confront a paradox in their own tradition: their Torah laws applied only to them, and to proselytes, but their God, they believed, was the one and only God of all. This situation led to new interpretations of the Torah, some of which were influenced by Hellenic thought and in response to Gentile interest in Judaism. It was in this period that many concepts from early Greek philosophy entered or influenced Judaism, as well as debates and sects within the religion and culture of the time.
