Apos- my point was that Marcion’s extreme rejection of the Judaic roots of the Christian faith was heretical- a violation of the very historical & theological context in which Jesus & the Apostles (Paul included) operated. While I consider, for example, the Constantinian era Church’s rejection of Judaic-Christian practices such as Sabbath & Passover-keeping to be tragic, it wasn’t that blatant a split with original C’nity as Marcion’s equating Jehovah with Satan. But thanks for the clarification.
You know, the Satan theology I haven’t heard too much about, so you’ll have to expand on it some more. But Maricon’s bits about how the Jews were a failed people seem to fit pretty solidly in the Pauline tradition, simply extending things Paul had said about how to reinterpret the Jewish cannon (as a continuing rejection of Jesus). The Gospels actually seem to have some of the same threads in there as well, particularly if you buy the explanation that part of their purpose for putting Jesus’ teachings into narrative form is in part to explain why the Temple State, and the Temple, were destroyed.
This discussion is becoming much too lucid, so I guess it’s time to bring up Morton Smith’s discovery of the letter from Clement of Alexandria advising the suppression of the Secret Gospel of Mark.
This esoteric teaching was, of course, the basis for my non-legendary misplaced Pit thread “Jesus: queer as $3 bill?” 
Let me hasten to add that I have nothing against Jesus. I believe he was a historical Jewish teacher who attempted to save Israeli from Roman domination by fulfulling several Messianic prophecies. But I am quite sure he would have NEVER equated himself with God, being a good Jew. Modern Christianity has much more to do with the teachings of Peter (who brought Jesus’ Jewish mysticism to Gentiles) and Augustine (who formulated the wacky Trinity doctrine) than those of poor Jesus. In other words, Nietzche was sadly correct: “There was only one Christian, and he died on the cross.”
There’s a tremendous amount of good academic research out there; it’s worth spending a day and a sack full of nickels (for photocopies) at your nearest college library.
