Muilenburg, James. "Chapter Ten: Conclusion." The Literary Relations of the Epistle of Barnabas and the Teaching of the Twelve Apostles. Marburg, 1929, 165-168.
Muilenburg finds that the overall question is one of a literary relationship between Barnabas and the Didache. The solution, as he sees it, is a recognition that Barnabas preceded the Didache and represents a piece of fervent teaching, while the Didache is a measured compendium of Christian teaching (Muilenburg 1929, 165). Barnabas is taken to be the composition of one author, while the Didache appears to be a composite work (Muilenburg 1929, 166). The materials adapted in both are overwhelmintly Jewish, but have been adjusted in places to have a Christian outlook. They were recognized in their period and after as Christian works (Muilenburg 1929, 167).
