I admit that there is controversy over this, but today most Bible scholars believe the lineage in Luke is of Mary. There is some argument that Joseph's lineage is in Luke while Mary's is in Matthew, but as I said, most scholars believe that the lineage in Luke is that of Mary. There is no doubt that the two lines are different from David on, so they canno ...[text shortened]... se, without (as I said) totally abandoning the tradition that lineages be patrilinear in nature.
“the son (as it was assumed) of Joseph.” Luke contains the genealogy of Joseph, tracing his ancestry through David via David’s son Nathan. In contrast, Matthew contains the genealogy of Mary and traces her ancestry through David via David’s son Solomon. Nathan and Solomon were full brothers, both being the sons of David and Bathsheba (1 Chron. 3:5; cp. 2 Sam. 5:14; 1 Chron. 14:4). The Gospel of Luke never mentions Mary for the simple reason that it is not her genealogy. Similarly, Matthew never mentions Joseph, the husband of Mary, because it is not his genealogy (the Joseph in Matthew 1:16 is the father of Mary, see commentary on Matthew 1:16).
Once we realize that Matthew has Mary’s genealogy and does not mention Joseph at all, and Luke has Joseph’s genealogy and does not mention Mary at all, two things happen: the genealogies makes sense (one genealogy for Mary and one for Joseph), and also many fanciful explanations for the two genealogies is eliminated. For example, some commentators have concluded that both genealogies belong to Joseph, saying that by custom Joseph had two different fathers, a real father, Jacob, and a levirate father, Heli. But that is clearly an assumption to solve a problem that does not actually exist, and it creates another and larger problem: it would mean that Joseph has two genealogies while Mary has none.
Most of the commentators who say that Matthew is Joseph’s genealogy and Luke is Mary’s genealogy realize that each parent should have a genealogy. However, they anchor their argument in their belief that Matthew 1:16 is referring to Joseph the husband of Mary (but it is not!), and based on that they say Matthew’s genealogy has to be about Joseph and Luke’s about Mary, even though Luke does not mention Mary. They answer the objection that Luke’s genealogy does not mention Mary by saying it does not have to since Luke chapter 1 made it clear that Mary was the mother of Jesus. Our rebuttal is that both Matthew and Luke make it clear that Mary is the mother of Jesus, but in the actual genealogical list, Matthew mentions only Mary while Luke mentions only Joseph.
Defenders of the position that Luke has Mary’s genealogy point out that the Talmud says Heli was the father of Mary, not Joseph, and therefore Luke must contain Mary’s genealogy. Our rebuttal to that line of reasoning is that the Talmud was written centuries after Christ, and the animosity between the Jews and Christians had been going on for years. It is well known that in the centuries after Christ the Jews did many things to try to prove that Jesus was not the Christ. As late as when the Gospel of Luke was written (likely 50-65 AD; more than 20 years after Jesus was crucified) the Jews were still aggressively promoting that Jesus was not the Christ, which is why Luke says that it was “assumed” he was the son of Joseph. The Jews did not believe he was the Son of God. The Jews also promoted that Jesus’ body was stolen from the grave by his disciples (Matt. 28:15-17). They also discounted many of the Messianic prophecies so that Jesus could not be said to have fulfilled those prophecies. For the Jews, whether accidentally or on purpose, misunderstanding the genealogy in Luke would be just one more way to show the New Testament was confusing and erroneous. It should be recognized that believers such as Sextus Julius Africanus (c. 230), who predates the Talmud, wrote that Luke gave Joseph’s genealogy, and so did a number of the Church Fathers.
Despite all the rhetoric (some of it quite ungodly, even involving name-calling) about the genealogies in Matthew and Luke, the solution is quite simple. God gave us a mathematical key in Matthew that, along with the Aramaic text, makes it clear that Matthew has Mary’s genealogy, which is why Matthew mentions Mary and not Joseph. Luke, on the other hand, mentions Joseph and not Mary because it is Joseph’s genealogy.
