He (Brown) also claims some “facts” in “Angels and Demons.” For example: “Christians got Holy Communion from the Aztecs” and “got the name for ‘Satan’ from the Islamic language, [sic] which they considered dirty.”

Of course you know this, but for quick rebuttal:

Christians got Holy Communion from the Aztecs”

Good trick, in that communion existed long before 1492, when Columbus sailed the ocean blue (and Europeans stumbled onto the heart-carving Aztecs).

In reality, of course, Communion stems from the Last Supper, and, before that, the Passover Seder meal itself.

. . “got the name for ‘Satan’ from the Islamic language, [sic] which they considered dirty.”

Not sure what "Islamic language" is, but Islam, again was created some 600 years after Christianity and its writings, making this impossible. (There is a "Shaitan" in Islamic writings (who is pretty much the same temptor), but mohammed clearly was borrowing from earlier Jewish and Christian writers, not the other way around.)

In reality, the name "Satan" is from the Hebrew "Satan'el" or "Ha-Satan" which was an angel whose job it was to tempt man -- then turn around and accuse the sinner on high. (A slight distinction from the Christian concept, in that devil is not "in rebellion," but rather doing his rather nasty job -- albeit a job in which he excels and enjoys a bit too much.)
