The obvious difference between them and the rest of the Roman world was that they were radical monotheists. They believed that there was one and only one God. But in many ways, the number of gods worshiped was less important than the nature and character of the God of Israel. All of the pagan religions had origin stories for their gods. Not Judaism. The God of Israel simply was and is and will be forever. To put it another way, Israel’s God was self-existent.
