You're sort of changing the subject. My point was that there was no contradiction in the text you suggested. Do you concede the point?
Each Gospel had a slightly different purpose, a slightly different audience, and slightly different perspectives. While the tomb is important in all of them, I have no reason to believe that every minutia of detail is necessary, despite your assertion.
"You'd have much less work to do if only you could accept that the accounts do not all need to agree on everything."
Not sure what you are talking about. The only thing I was doing was demonstrating that your accusation of contradiction was erroneous. It doesn't, matter if someone else wants to harmonize it a different way, it would still prove that you are wrong. I have to wonder if you really paid attention when reading my posts.
"(though keep in mind that all of three of them source much of their material from Q),"
There is no manuscript evidence for Q, it's just a hypothetical explanation of similarities in the gospels.
I know about the textual transmission, variants, and gnostic gospels. I majored in linguistics and have studied this kind of stuff at the university level. You should watch this video I mentioned to someone else: https://www.youtube.com/watch?v=LuiayuxWwuI Its a bit slow for the first 10 minutes or so though, but it might shed some light on the scribal process for you, because I think you're only seeing one slanted view of it. Nobody but KJV-only-ists thinks that translation is inspired, but translation is not an issue because we have the original language texts. The history of the Bibles open textual transmission performed by numerous fallible scribes (in many languages and places) who could make scribal errors actually adds to the reliability of the text because of the multiple lines of transmission, it allows people to see textual families and locate the source of variants and changes; the video gets into that. If a bunch of people are simultaneously making copies, and people copy those copies, it creates textual families you can compare and perform textual criticism on to reconstruct the original text despite variants and fallible scribes. The extremely large number of new testament manuscripts we have makes the new testament one of the most reliable texts of antiquity
