In some ways I agree. I don't mean to make this about you, but I personally think you are well identified as a gnostic because plenty of early
(2nd century) Christians, though they were later expelled from the Catholic
(not necessarily Roman, just "universal") body, agreed with what is now called the "
Heresiarch" Marcion that the god or God of the Old Testament and the "Father" of Jesus Christ were and are far from identical. They were known more as Marcionites than Christians. Then again, the original followers of Jesus weren't called Christians until
Antioch, and, by then, St. Paul had become a predominant, vocal apostle, so it could be said that they were converts to his version of Christianity, to the "Pauline sect." As I recall having read, Marcion used the verse cited in your op to help prove his case: "
... every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit." and concluded, in some ways logically enough, it seems to me, that, because the offspring of Adam and Eve are said to be born in "original sin," they must have been produced by a corrupt tree.
To me, the
History of Christianity is fascinating. In terms of doctrines
(and dogmas), it continuously morphed in the early decades until it finally congealed into something approaching an uneasy "orthodoxy." Tensions remain, and not just those which arose during the Protestant Reformation. Even on this board, and as it relates to early "heresies," I see those who tend toward Ebionism, a return to the observance of the Laws of Moses, including the Sabbaths, on one hand, and others, such as Marcion, on the other hand, who would be done with the Old Testament altogether. The "orthodox" remain between these two polar extremes.
