§ 30. THE THEOLOGICAL LITERATURE OF THE POST-APOSTOLIC AGE, A.D. 70-170.[53] The literary remains of the so-called Apostolic Fathers constitute the first fruits of Patristic-Christian literature. These are in respect of number and scope insignificant, and, inasmuch as they had their origin, from the special individual circumstances of their writers, they were composed for the most part in the form of epistles. The old traditional view that the authors of these treatises had enjoyed the immediate fellowship and instruction of the Apostles is at once too narrow and too wide. Among these writings must be included first of all the recently discovered “Teaching of the Twelve Apostles.” About A.D. 130, when Christianity was making its way among the ranks of the cultured, Christian writers began to feel themselves called upon to engage with paganism in a literary warfare defensive and offensive, in order to repel the charges and calumnies raised against their religion and to demonstrate its inner worth in opposition to the moral and religious degradation of heathenism. These writings had a more theological and scientific character than those of the Apostolic Fathers, which had more of a practical and hortatory tendency. The works of these Apologists still extant afford interesting and significant glimpses of the life, doctrine, and thinking of the Christians of that age, which but for these writings would have been almost unknown. § 30.1. =The Beginnings of Patristic Literature.=--According to the established rule of the church we have to distinguish between New Testament and Patristic literature in this way: to the former belongs those writings to which, as composed by Apostles or at least under Apostolic authority, the ancient church assigned an objectively fundamental and regulative significance for further ecclesiastical development; while in the latter we have represented the subjective conception and estimation which the Church Fathers made of the Christian message of salvation and the structure they reared upon this foundation. The so-called Apostolic Fathers may be regarded as occupying a position midway between the two and forming a transition from the one to the other, or as themselves constituting the first fruits of Patristic literature. Indeed as regards the New Testament writings themselves the ancient church was long uncertain and undecided as to the selection of them from the multitude of contemporary writings;[54] and Eusebius still designated several of the books that were subsequently definitely recognised ἀντιλεγόμενα; while modern criticism has not only repeated such doubts as to the genuineness of these writings but has extended these doubts to other books of the New Testament. But even this criticism cannot deny the historical significance assigned above to those New Testament books contested by it, even though it may
