For example, Terry, this is one of the reasons why I said that his view seems very outdated on the subject
The creed we find in 1 Cor 15:3–5, as it has already been shown, did not really have time to “develop” in any meaningful sense, since it stands too close to the events themselves. Most modern scholars agree that its date falls within a range extending from a few months to, at most, two or three years after Jesus’ death.
But on the broader issue we were discussing (namely, the development of traditions) maybe Rob should consider the following:
“If, as I shall argue in this book, the period between the ‘historical’ Jesus and the Gospels was actually spanned, not by anonymous community transmission, but by the continuing presence and testimony of the eyewitnesses, who remained the authoritative sources of their traditions until their deaths, then the usual ways of thinking of oral tradition are not appropriate at all.”— Richard Bauckham, Jesus and the Eyewitnesses: The Gospels as Eyewitness Testimony (Grand Rapids, MI: Eerdmans, 2006), p. 12.
“Our argument is rather that the continuity of the Gospels is with the testimony of the eyewitnesses, not via a long period of community transmission but through, in many cases, immediate access to the eyewitnesses or, in other cases, probably no more than one intermediary.”— Richard Bauckham, again from the same book, this time from page 136
“The fact that the form critics neglected the factor of living memory and treated the transmission of Gospel traditions as analogous to transmission over much longer periods accounts for the impression one often gets from reading modern Gospels scholarship that the period between the events and the Gospels was a very much longer one than it actually was. In fact, it was the period in which the eyewitnesses were still alive and available to tell their stories.”— Richard Bauckham, this time from “The Transmission of the Gospel Traditions,” in Actes du Congrès La Recherche du Jésus historique (2009), p. 383.
By contrast, Rob seems to hold a historical-critical view that is, as I said, badly outdated.
Let me quote Bultmann, for example, who was probably the most important scholar representing the early “mythical” view of the historical Jesus, this is what he said: “I do indeed think that we can know almost nothing concerning the life and personality of Jesus, since the early Christian sources show no interest in either, are moreover fragmentary and often legendary; and other sources about Jesus do not exist.”— Rudolf Bultmann, Jesus and the Word (New York: Scribner’s, 1958 19261926), p. 14.
Also, in the late nineteenth century, scholars such as Bruno Bauer, Abraham Loman, Rudolf Steck, and Willem C. van Manen rejected the authenticity of all the Pauline letters, including 1 Corinthians, arguing that their developed theology pointed to a period later than the mid-first century.
This kind of reductive view of the historicity of the Gospels and the New Testament is, in 2026, extremely outdated and is essentially no longer held by any serious contemporary scholar. I can understand why someone might still find it appealing, but modern historiography has, for all intents and purposes, moved beyond it.
