Schaff, Philip. "Document IV: Hermas." Oldest Church Manual Called the Teaching of the Twelve Apostles. Second Edition, Revised and Enlarged. New York: Funk & Wagnalls, 1886, 233-235.
Schaff describes the Shepherd of Hermas as "a guide of Christian morality in the shape of an allegory or romance" (Schaff 1886, 233). It contains "two parallels to the first and second chapters of the Didache, with some features resembling Barnabas (Schaff 1886, 233). Schaff dates Hermas later than the Didache. He then presents Commandment II.4-6 and VIII.3-5 in Greek and English without comment (Schaff 1886, 234-235).
