The Shepherd of Hermas was in circulation in the latter half of the second century, and is quoted by Irenæus (Adv. Hær. IV. 20. 2) as Scripture, although he omits it in his discussion of Scripture testimonies in Bk. III. chap. 9 sqq., which shows that he considered it not quite on a level with regular Scripture. Clement of Alexandria and Origen often quote it as an inspired book, though the latter expressly distinguishes it from the canonical books, admitting that it is disputed by many (cf. De Prin. IV. 11). Eusebius in chap. 25 places it among the νόθοι or spurious writings in connection with the Acts of Paul and the Apocalypse of Peter. According to the Muratorian Fragment it was “written very recently in our times in the city of Rome by Hermas, while his brother, Bishop Pius, sat in the chair of the Church of Rome. And therefore it also ought to be read; but it cannot be made public in the Church to the people, nor placed among the prophets, as their number is complete, nor among the apostles to the end of time.” This shows the very high esteem in which the work was held in that age. It was very widely employed in private and in public, both in the East and the West, until about the fourth century, when it gradually passed out of use. Jerome (de vir. ill. 10) says that it was almost unknown among the Latins of his time. As to the date and authorship of the Shepherd opinions vary widely. The only direct testimony of antiquity is that of the Muratorian Fragment, which says that it was written by Hermas, the brother of Pius, during the episcopacy of the latter (139–154 a.d.). This testimony is accepted by the majority of scholars, most of whom date the book near the middle of the second century, or at least as late as the reign of Hadrian. This opinion received not long ago what was supposed to be a strong confirmation from the discovery of the fact that Hermas in all probability quoted from Theodotion’s version of Daniel (see Hort’s article in the Johns Hopkins University Circular, December, 1884), which has been commonly ascribed to the second century. But it must now be admitted that no one knows the terminus a quo for the composition of Theodotian’s version, and therefore the discovery leaves the date of Hermas entirely undetermined (see Schürer, Gesch. des jüdischen Volkes, II. p. 709). Meanwhile Eusebius in this connection records the tradition, which he had read, that the book was written by the Hermas mentioned in Romans xvi. This tradition, however, appears to be no older than Origen, with whom it is no more than a mere guess. While in our absence of any knowledge as to this Hermas we cannot absolutely disprove his claim (unless we prove decisively the late date of the book), there is yet no ground for accepting it other than a mere coincidence in a very common name. In Vis. II. 4. 3 Hermas is told to give one copy of his book to Clement. From this it is concluded by many that the author must have been contemporary with the well-known Roman Clement, the author of the Epistle to the Corinthians. While this appears very likely, it cannot be called certain in the face of evidence for a considerably later date. Internal testimony helps us little, as there is nothing in the book which may not have been written at the very beginning of the second century, or, on the other hand, as late as the middle of it. Zahn dates it between 97 and 100, and assigns it to an unknown Hermas, a contemporary of the Roman Clement, in which he is followed by Salmon in a very clear and keen article in the Dict. of Christ. Biog. Critics are unanimously agreed that the book was written in Rome. It consists of three parts, Visions, Mandates, and Similitudes, and is of the nature of an apocalypse, written for the purpose of reforming the life of the Church, which seemed to the author to have become very corrupt. The work (especially the last part) is in the form of an allegory, and has been compared to the Pilgrim’s Progress. Opinions are divided as to whether it is actually founded upon visions and dreams of the author, or is wholly a fiction. The former opinion seems to be the more probable. Until recent years only a Latin translation of Hermas was known. In 1856 the first Greek edition was issued by Anger and Dindorf, being based upon a Mt. Athos ms. discovered shortly before by Simonides. Of the ten leaves of the ms. the last was lost; three were sold by Simonides to the University of Leipsic, and the other six were transcribed by him in a very faulty manner. The Sinaitic Codex has enabled us to control the text of Simonides in part, but unfortunately it contains only the Visions and a small part of the Mandates. All recent editions have been obliged to take the faulty transcription of Simonides as their foundation. In 1880 the six leaves of the Athos Codex, which had been supposed to be lost, and which were known only through Simonides’ transcription, were discovered by Lambros at Mt. Athos, and in 1888 A Collation of the Athos Codex of the Shepherd of Hermas by Dr. Spyr Lambros was issued in English translation by J. A. Robinson, at Cambridge, England. We thus have now a reliable Greek text of nine-tenths of the Shepherd of Hermas. Hilgenfeld, in his last edition (1887) of his Novum Test. Extra Can. Rec., published also a Greek text of the lost part of the work, basing it upon a pretended transcription by Simonides from the lost Athos ms. But this has been conclusively shown to be a mere fraud on the part of Simonides, and we are therefore still without any ms. authority for the Greek text of the close of the work. Cf. Robinson’s introduction to the Collation of Lambros mentioned above, and Harnack’s articles in the Theol. Literaturzeitung (1887). The most useful edition of the original is that of Gebhardt and Harnack, Patrum Apost. Opera, Fasc. III. (Lips. 1877). The work is translated in the Ante-Nicene Fathers, Vol. II. The literature upon the subject is very extensive, but the reader should examine especially the Prolegomena of Harnack in his edition. Cf. Zahn’s Hirt des Hermas (1868), and the article by Salmon in the Dict. of Christ. Biog. II. p. 912 sqq. Cf. also chap. 24, note 20, in regard to the reasons for the non-canonicity of the Shepherd.
