@wim_v12e Thanks for mentioning that! I read about all this in a book by Bart Ehrman, who didn't mention the gnosticism connection at all: I learned about that only in Wikipedia. But, after only thinking about it for only a few minutes, the connection seems anachronistic—Marcion seems to have simply taken Paul's ideas about Law vs Gospel to the natural logical conclusion. I wouldn't invoke anything mystical or secret about Marcion's views, just, a wackiness, and mayyybe political naivete :)
