I appreciate your point but I don't see a distinction between one witness and numerous witnesses since there's a sole source of information -- the Christian Bible.
But the Bible is not a single source book. While it is a matter of theory whether Matthew or Mark came first and served as a basis for the other Synoptic Gospels, Luke as a Greek trained physician has proven to be a first-class historian of that era. He documents that he literally researched the accounts to verify them. In addition, John was written significantly after the Synoptic Gospel accounts.
Acts itself is a history like other Scriptural history that is not centered on boosterism, the faults and follies of the Apostles are as much on display as their accomplishments.
The Epistles were written by no less than five people. The books that make up the Epistles were originally written as letters to the Churches and received wide circulation.
The aspect of having multiple witnesses shows that Jesus made an impression that was universal. It is not so much a matter of wishing something true, healing a man born blind was never done before -and was able to be backed up as a fact by a lifetime of that man's family, friends and townspeople that knew him first hand.
It is not a matter that they wished it true by fervent belief, if you read the Gospel accounts, which you say you haven't, then you would find that often the apostles did not "get it" and did not understand. Their fervent belief was rather shaky at first and they did not become bold ambassadors for the Lord until after the baptism by the Holy Spirit, prophesized by Jesus.
The change that enabled the Apostles was stark and dramatic. This is recorded by the many witnesses that came to faith that day. And if their witness of the conversion of 3000 on the day of Pentecost was not true, then it would be common knowledge.
This acceptance of witness to establish fact is just as it is used in the Courts today. Multiple witness establishes the truth to what Jesus said and did as much as what Moses said, or Job, or Noah, or any of the Prophets.
Your complaint about Josephus is specious as well. On the one hand, if he just "hears about" Jesus, his testimony is not valid, and if he witnessed Jesus' words and deeds then we can't rely on it.
Like the establishment of fact by common witness in this era, the same can be said to be true of the OT narrative accounts, which makes up about 50% of the Old Testament. Once a fact was known, it was not necessary to prove it, it was common knowledge by the testimony of many witnesses. At certain times the OT authors will even reference books long since lost in antiquity as if to say, 'well enough of this is known that he doesn't have to prove it.'
TWA Dude mimics the post-modernist that has no firm foundation of absolute. Truth is not truth, but whatever you believe it to be.
But the ethical theist says that there is an absolute truth and that it has been revealed to men and women by God.
This is the possibility many cannot allow; the Gospel accounts and Epistles are true.
But this is exactly what many witnesses in unison testify to -an establishment of fact. Because they didn't have videotape, cassette tapes, or cameras, there is no other way to tell the truth than through the spoken and then written word.
With as much opposition that existed for the earliest Christians, before those Jews that were Christian were even known as or called Christian, had these witnesses been false, this new faith would have been crushed by exposure. Instead, they were persecuted, which makes sense to me: when you can't fight the common knowledge of the people, attack them outright instead.
