Young, Stephen E. "Chapter Ten: Conclusions." Jesus Tradition in the Apostolic Fathers. Tübingen: Mohr Siebeck, 2011, 278-284.
Young concludes based on his earlier chapters that it is probably that appeals to Jesus traditions in the Apostolic Fathers are primarily to materialls which were readily available in oral form (Young 2011, 278). Though some citations are likely of written sources, for the most part, the culture's emphasis on orality would make consultation of written sources largely unnecessary. This also suggests that the Q traditions may rightly be viewed as at least partially oral in nature (Young 2011, 280).
Young also concludes that, at least as used in the Apostolic Fathers, oral traditions tend to be conservative of information, stable in message but variable in wording, mnemonically sensitive, and targeted to ideas which are socially relevant (Young 2011, 281-282).
Young concludes with some questions which his research has brought up and which may serve to inspire further research (Young 2011, 283). These questions largely involve the usage of the canonical Gospels as compared to non-canonical traditions about Jesus. In oral cultures, a written text would still be used as oral/aural medium. We might wonder, then, to what extent the canonical writings were used and what distinguished their use from other sources of teaching. Young's work lays a foundatin and proposes some methods of study which could prove to be of lasting usefulness as we grapple with all these questions.
