Therefore my explanation is right on the point, locating the error with the offenders, and not with the others, who do not make that error.
As I pointed out above, you have no evidence or logical argument to support your claim that the inclusion or absence of the nativity information is a error on the part of any of the Gospel writers, because there exist various valid alternative explanations for why that happened. And you have provided no logical arguments or proof of why your theory has to be regarded as the only true one.
You have a lot of unproven assumptions behind why you think that's the only possible answer - but you haven't proven any of your underlying assumptions are true either about the creation of the NT. Which even further undermines your attempt to claim that your explanation of what we see in the Gospels must be regarded as the truth.
If you wish to claim that Paul specifies that Mary was the mother of Jesus and that Mary was a virgin when Jesus was conceived, now's the time to set out the verses on which you rely.
Logical fallacy, "shifting the burden of proof".
Since you are the one making the claim that Paul did not believe in the virgin birth, the onus is on you to prove your claim is true with logical argumentation and facts.
You're committing the logical fallacy also of "argument from silence" by assuming that silence proves he must not have believed it. And I've already explained in the preceding posts in greater detail why your entire line of reasoning is fallacious and invalid.
You did not respond to my points. Instead you just ignored them and continued to repeat your disproven claims.
But the Septuagint specifies her as a virgin. And that's plainly the motive of Matthew's and Luke's authors in inventing a virgin mother for Jesus.
Logical fallacy, argument by assertion and argument by repetition.
You cannot claim as true that Matthew or Luke made that information up because you have given no evidence or valid arguments to support such a claim.
And continuing to repeat your unproven claim doesn't prove your claim.
So any speculation on your part of their motive becomes irrelevant when you can't even prove they did anything to begin with.
With all due respect, don't be silly.
Logical fallacy, "Argumentum ad lapidem". Trying to dismiss my argument as "silly" doesn't disprove the validity of my arguments or the truth of my conclusions.
Logical fallacy, "argument by assertion". Merely claiming I did not disprove your points doesn't make it so. You need demonstrate with logical argumentation that your points are still valid, in light of my arguments, by trying to counter my arguments with new arguments or facts.
All you've done most of this thread is merely repeat your original claims while ignoring most of the points I've made which disproved them.
And, you'll note in my preceding posts, that I never merely accuse you of disproving nothing and then walk away: I actually demonstrate why your responses failed to disprove what I said: Using logic and facts to show that your arguments were either invalid or your assumptions were wrong.
That's called a counter argument.
In a debate, counter arguments are required. You can't merely keep repeating your original claims while ignoring the other side's counter points that refute your claims.
To do so makes you guilty of the logical fallacy of argument by repetition and argument by assertion. Something isn't true just because you assert it is. And it isn't true just because you repeat it. You need to be able to logically defend it against counter arguments if you want to be able to claim it's true.
You declared that the gospel authors all know and agree with what the others were saying even when they don't mention what the others were saying.
The key difference here you're missing is why I can say that; Because I'm basing my conclusion off historical documentation that says that is what happened.
Ie. I have a valid evidence based reason for reaching certain conclusions about the authorship and transmission of the Gospels. And I have already stated some examples of that, which you have ignored.
You, in contrast, have presented no evidence that would dispute what the historical record says on this matter.
Merely asserting the historical record is wrong doesn't make it true. You need to give valid reasons and evidence to prove that claim.
Yet as I pointed out, the authors of Mathew and of Luke took Mark and rewrote it to please their respective selves.
Logical fallacy, argument by assertion, and argument by repetition.
You don't prove your claim true just by asserting it's true.
You have to give evidence with valid logical reasoning that would prove your claim is true.
They disagreed with Mark on various points and they disagreed with each other on various points.
Logical fallacy, argument from silence.
Silence on a matter proves nothing other than the fact that there is silence.
You cannot claim silence means disagreement.
By definition, "disagreement" (like "contradiction") requires two things to compare to each other.
You cannot logically show a disagreement, by definition, by comparing something to nothing, when there is no logical reason to conclude the absence of something represents a choice based on disagreement.
I already explained in more detail in preceding posts why this line of reasoning by you is invalid, using a fallacious argument from silence, and you haven't addressed those points I made.
