I think this needs careful handling. Astrology and mysticism is not the same as the worship of the Olympians, is it?
What we’re discussing here is the tendency of Jewish people of a certain kind to become involved in ancient magic. This sort of thing certainly went on; but isn’t relevant.
Surely we know very well that the Jews did NOT embrace paganism. Certainly some did – we see that in Maccabees – but they ceased to be Jews in the process.
To anyone who wishes to tell me that the early Christians were syncretic, I have two obvious questions: 1. where is the evidence, and why are you disregarding the endless anti-pagan statements throughout the fathers? and 2. if the early Christians were syncretic, why did they refuse to sacrifice?
Some people will then say that some early Christians DID sacrifice; but we will find, on examination, that they are labelling as “Christians” those whom the early Christians (including people like the apostle John) labelled as “heretics” and expelled from their congregations.
But as I say, people may say anything. Anyone who wishes to suggest that the early Christians were not hostile to paganism is welcome to produce quotations from the fathers saying so. These do not exist, of course.
All the best,

PS: pardon me if this is terse - I have a raging headache and no time to answer properly. Just be aware that all this line of argument involves intentional jiggery-pokery.
