The ones I was refering to were Polycarp, Clement of Rome, Ignatius and the such like.
So it is not accurate for you describe my intimation and evidence as unfair, My point was that from the earliest traditions the writings as we now have them could be traced to the original source without any real modification. I was not saying that every writer mentioned the killing of the children, only that there is no valid reason for doubting Matthew, or that Matthew was actually contemporary with that event.
So, am I to understand that the arugment is that, because people such as Polycarp and Clement, whose lives may have overlapped with the author of Matthew, had read Matthew, and didn't accuse him of being a liar, this lends support to the veracity of Matthew?
This seems like a strange argument to make. Regarding the specific case of the Massacre of the Innocents, remember that you were also claiming it wouldn't have been that significant an event at the time. These church fathers obviously accepted Matthew's word about things, that's why they became leaders of the church, but how would they have verified this insignificant event that Matthew claimed happened decades before? Polycarp's birth is generally dated about 35 years after Jesus' death, so what significance does it have for him not to doubt Matthew's word. It would be like me joining a new religion, and not doubting the word of the teachers about some fairly insignificant event that happened during the Frist World War. Even with Ignatius we're talking about an event that is supposed to have happened during the Chinese Civil War. And these aren't people with internet, or TV, or exhaustive libraries.
You can't simultaneously dismiss the silence of people like Josephus by arguing that the event wouldn't have been considered widely significant; and then cite as support the fact that early Christians don't question the story decades or centuries later. Why should they?
