>>6060853Tacitus said this about the [pre-Christian] Jewish religion: The Egyptians worship many animals and images of monstrous form; the Jews have purely mental conceptions of their Deity, as one in essence. They call those profane who make representations of God in human shape out of perishable materials. They believe that Being to be supreme and eternal, neither capable of representation, nor of decay. They therefore do not allow any images to stand in their cities, much less in their temples. This flattery is not paid to their kings, nor this honour to our Emperors.
The belief of an abstract and formless God seems entirely unique to Judaism both in antiquity and even today.
