Most of the non-canonical gospels have been dated second century or later and I wanted to know if any other gospels have been dated to around the time of Mark, Matthew, Luke, or John. If so, are they still relatively intact or small fragments?
Good question. As I am sure you know, even the canonical gospels cannot be “dated” (if you mean, scientific dating, as in “carbon dating”, for example) to the first century, since we do not actually possess any copies from the first century.
There must have been another gospel, Q, since Mark, Matthew and Luke appeared to have drawn from it and quoted, but we do not have a copy of it.
From what I have read and heard, scholars seem to be in agreement that the four canonical gospels are indeed the earliest ones. And yes, I have heard of the speculation that The Gospel of Thomas may be earlier than even Mark.
I know this isn’t much help, but just thought I’d join the conversation…
