Schaff, Philip. "Document II: A Latin Fragment of the Doctrina Apostolorum." The Oldest Church Manual Called the Teaching of the Twelve Apostles. Second Edition, Revised and Enlarged. New York: Funk & Wagnalls, 1886, 219-225.
The Latin fragment of the Doctrina Apostolorum reproduces material found in the Didache's Two Ways narrative. Schaff had previously referred to the fragment in chapter 26 (Schaff 1886, 219). He reproduces the Latin and a parallel English translation of the fragment (Schaff 1886, 219-220). before appending critical comments provided by B. B. Warfield. The remainder of the chapter is by Warfield.
Warfield considers as a "cultural problem" the relationship between the Didache and the Epistle of Barnabas (Schaff 1886, 220). The wording of the Latin fragment corresponding to that of Barnabas strikes Warfield as evidence that Barnabas was dependent, at least in part, on some version of the Didache (Schaff 1886, 221). Warfield sees Barnabas' style to be that of adding to an argument and makign a lengthy discourse from a few borrowed words. Other documents known to be dependent on this portion of the Didache do not have the expansion seen in Barnabas.
Warfield goes on to describe the textual differences among these documents (Schaff 1886, 221-222). He then concludes as follows. "We have two well-marked recensions of the Didache text, - the one represented by the old Latin, Barnabas, and the Canons, and the other by the Bryennios MS and the Apostolical Constitutions" (Schaff 1886, 222). He therefore takes all the variants to have some relation to an original text of the Didache. Warfield sees an underlying version of the Didache used by Barnabas, but that some alterations came into the text afte rthat time, up to the version copied by the scribe Leon in the 11th century (Schaff 1886, 223).
Warfield moves on to trace the supposed transmission of the Didache. He proposes two stages. One he finds in Barnabas and the Canons. The other he traces through Hermas, Clement of Alexandria, and the Apostolical Constitutions. This second he considers to have led to the Constantinopolitan Manuscript we have (Schaff 1886, 224). He is quick to say that the variation is not very great (Schaff 1886, 225).
