Niederwimmer, Kurt. "Der Didachist Und Seine Quellen." in Jefford, Clayton (editor). The Didache in Context: essays on its text, history, and transmission. Leiden: Brill, 1995, 15-36.
Niederwimmer considers the overall nature of the text of the Didache, evaluating whether it may have been more like a series of notes of the nature of a draft or whether it is rightly considered a finished product. The text seems to have some elements of adopted tradition and other elements which may have come from current practices at the time of composition (Niederwimmer 1995, 16). Other elements may well be tied to various bits of Jesus traditions, either adapted from canonical Scriptures or from since lost writings or oral traditions (Niederwimmer 1995, 17). Niederwimmer indicates his various sources by means of abbreviations, mostly inserted in the margins and footnotes of his Greek text.
Prior to the text itself, Niederwimmer provides an extensive bibliography of sources for his manuscript study and the locations of parallel texts, allowing a scholarly reader to evaluate his analysis (Niederwimmer 1995, 19-21).
The Greek text itself begins on p. 22. Of particular interest to me for the purposes of my project is the material beginning at 7.1 (Niederwimmer 1995, 29). Unfortunately, while Niederwimmer cites numerous studies which refer to these passages, his footnotes cite secondary sources rather than going directly to the primary materials. Therefore, I note that it may be helpful to revisit pages 29-35, but not immediately.
