The Gospel of John, which is not Marcionite, clearly has a layer which denies Jesus Davidic descent and denies he is the Davidic messiah
John 7:41-42, dispute about Jesus:
Others said, "This is the Christ." But some said, "Is the Christ to come from Galilee? Has not the scripture said that the Christ is descended from David, and comes from Bethlehem, the village where David was?"
This is a factional dispute among Christians, whether the messiah is of Judah (David or a "son of David") or Israel (Joseph or a "son of Joseph" or "Joseph's son").
The Marcionites are but one of many sects that opposed Davidic origin in favor of Josephine origin. In fact the Macrionites broke even with Josephine sects holding that Jesus had no earthly lineage.
John is the gospel that retained most of the Josephine elements, Matthew the gospel that emphasized the Davidic elements the most. The Christianity we have is a compromise, where Joseph has been transformed from Jacob/Israel's son and father of Ephraim and Manasseh (i.e., Samaria; Ephraim is where Shechem, the rival temple of Jerusalem sat) whose seed Jesus was descendant from, to the immediate "step-father" whose sperm did not impregnate Mary. Note Matthew retained Joseph as son of Jacob, but this is a "random" Jacob, the son of Matthan (= Matthew?); Luke breaks the lineage further, by changing Joseph's father from Jacob to Heli (Eli) another son of Matthan. The seed of David designation is a bit of a mess, as Jesus is supposedly conceived without human seed, but from God (Jewish critics had a field day with that).
The point is a much wider dispute existed before doctrine was settled on lineage and authority. The Marcionites represent a later stage development of the Josephine side, as it breaks entirely from the exegetical foundation for the messiah. That the Marcionites seem to have bundled the first New Testament, and were among the first to popularize the gospel as an instrument of evangelism, tells us that the New Testament writings are not from the earliest Christianity, but rather from the era of evangelism, the rapid expansion of Christianity from small dedicated communities to the general public at large.
Note, the house divided parable may have to do with the internal division within Christianity over the origin/authority point, and how is causes schisms. It can be seen as part of a push for the unified theology that tried to accommodate as many factions as possible by absorbing elements of each sides teaching, tilting of course to the orthodoxy that controlled most of the hierarchy.
