Heli was Joseph's father in law. That was explained in my post above. They didn't use the term father in law and genealogically that is the way it was done.
The problem with this is that Luke unequivocally states that Heli was Joseph's father, "Joseph, son of Heli". If they had no term for father in law, then there are other ways that relation can be described. If it is true that in that time Jewish genealogy was simply done that way, you need to show that using an unbiased source. I don't know enough about 1st century Jewish genealogy to know if that is the case, and I am not simply going to accept your word for it..
Remember, the Jews in Jesus' time didn't protest his chronology and they surely would have if there were any discrepancies. You are looking at it with a logical, but untrained eye.
I can't remember that because I don't know it to be true. The author who wrote Luke did not write it in Jesus' time. The most charitable dates for that gospel have it being written 50 years later, after the fall of Jerusalem. Those early dates are no longer considered accurate by most scholars, and the most likely date is closer to the beginning of the 2nd century. So, who would have known if there were any discrepancies? Matthew was writing his gospel around the same time, so perhaps he noted a discrepancy, and that is why he has it different. Perhaps it was the other way around, and Luke was correcting Matthew. There are multiple possibilities, one or the other got it wrong, they both got it wrong, or they both got it right, despite the differences. Only the last possibility requires mental gymnastics to overcome, pending your verifiable explanation of 1st century Jewish genealogy.
Then there is the problem that they both seem to agree on Joseph's grandfather, Matthan/Matthat (the names being so similar that they are likely the same person and some examinations of the genealogies treat them as the same person). Did Joseph marry his first cousin, then?
Matthan was the grandfather of Joseph, there were two people named Matthat the firs at Luke 3:29 and the second one, Mary's grandfather at Luke 3:23, 24.
I am referring to the Matthat from Luke 3:24. I will reiterate that Luke presents him as Joseph's grandfather, not Mary's. My other point was that given the very similar names, Matthat and Matthan, there is a likelihood that they are actually the some person, compounding the genealogical issue. They were basically the same name in Hebrew, as they are both derived from the same Hebrew root word, natan, meaning 'to give', and Matthat is never used in the Hebrew bible. Matthat is considered a transliteration. But let's leave the Matthat/Matthan issue aside, and concentrate on your understanding of 1st century Jewish genealogy for the time being.
Further, if you want to claim that Luke was actually tracing the genealogy through Mary, while telling us that he is tracing it through Joseph, that makes Luke a liar. If he would lie about that, what else does he lie about? If we have known liars writing books of the Bible, and lieing about the most mundane and boring aspects of the narrative like genealogies why should we believe the fantastic stuff about gods and miracles?
Luke didn't get it wrong, you did.
Oh, and here I thought the purpose of this thread was to "successfully refute" our challenges. This response seems to fall woefully short of that mark. It certainly looks like one or both of the gospel authors got it wrong, until you are able to prove your contention regarding 1st century Jewish genealogy. And, since you want to claim that Luke said one thing, while a different thing is true, I have no choice but to regard Luke as a liar for the time being.
Next up, and since it is on the same topic I am going to go ahead and ask it now: How is it that Matthew has 41 generations from Abraham to Jesus, and Luke has 56? That is a pretty big difference, don't you think?
That too was explained in the copy and paste and link I supplied on the subject above. You didn't need to have everyone listed in the genealogy, just the relevant ones, and anyway, they were doing different sides of the family.
First off, if you want to present an unbroken line from an ancestor to a descendant, yes, you do need to have everyone in that line listed in the genealogy. Secondly, 15 generations at 20 years per generation is a difference of 300 years, which their tracing different sides of the family does not adequately explain. A few generations would not be a problem, but 15 is. So, pick your poison.
