I want to list five reasons why I think we ought to assume that the gospels are reliable until proven wrong:

1. There was insufficient time for legendary influences to expunge the historical facts. The interval of time between the events themselves and recording of them in the gospels is too short to have allowed the memory of what had or had not actually happened to be erased.

2. The gospels are not analogous to folk tales or contemporary "urban legends." Tales like those of Paul Bunyan and Pecos Bill or contemporary urban legends like the "vanishing hitchhiker" rarely concern actual historical individuals and are thus not analogous to the gospel narratives.

3. The Jewish transmission of sacred traditions was highly developed and reliable. In an oral culture like that of first century Palestine the ability to memorize and retain large tracts of oral tradition was a highly prized and highly developed skill. From the earliest age children in the home, elementary school, and the synagogue were taught to memorize faithfully sacred tradition. The disciples would have exercised similar care with the teachings of Jesus.

4. There were significant restraints on the embellishment of traditions about Jesus, such as the presence of eyewitnesses and the apostles’ supervision. Since those who had seen and heard Jesus continued to live and the tradition about Jesus remained under the supervision of the apostles, these factors would act as a natural check on tendencies to elaborate the facts in a direction contrary to that preserved by those who had known Jesus.

5. The Gospel writers have a proven track record of historical reliability.

I don’t have enough time to talk about all of these. So let me say something about the first and the last points.
