You still left something unaddressed:
Aside from the title, where is the explicit claim made that John wrote the gospel named after him? What do we know about the title, and do the earliest manuscripts have the title? Lastly, why is it written in the third person omniscient? If John is reporting things as an eyewitness, why does he include events which he did not witness?
You partially addressed the question about third-person narration by saying that this is how honest men testified back in the day. Also, you addressed the title later in the post. However, you fail to explain how John was aware of events that he wasn't present for.
I also asked,
I've read this several times and it still makes no sense at all. You're telling me that a passage not being in the earliest manuscripts indicates that it was in the original.
I don't know what this has to do with authorship.
And these things you did address, so thank you for that.
I continue,
I hear this a lot, but I've never had a Christian give me even a single example. A single example would be a good start, but it would take several examples to establish a trend.
You responded to this with a dead link. Presumably the ellipsis that appears in your link was inserted by the forum, and then a large portion of the link was redacted. Until you fix that, this is unaddressed.
You did reply to my citation of Josephus, so we can get to that when everything else is addressed. You also addressed the issue of the title, as I already mentioned, so we can get to that later also.
So assuming you can fix the dead link, you still must account for both why and how John recorded events when he wasn't present to witness them. After that, we can address your responses.
