Matthew Brown Riddle,
Ante-Nicene Fathers Vol. VII, Introductory Notice…
(1885)
“ As regards the doctrine, polity, usages, and ethics expressed and implied in the Teaching, the reader can judge for himself. The writer is of the opinion that the work represents, on many of these points, only a very small fraction of the Christians during the second century, and that, while it casts some light upon usages of that period, it cannot be regarded as an authoritative witness concerning the universal faith and practice of believers at the date usually assigned to it. ”
