According to Harnack, the composition of the so-called Catholic Epistles and similar early Christian literature is to be assigned to them, and in this way he would account for the Apostolic features which are discoverable in these writings. He would not, however, attribute to them the fiction of claiming for their works an Apostolic origin, but supposes that the subsequently added superscriptions and the author’s name in the address rest upon an erroneous tradition.--The gradual disappearance of charismatic offices was mainly the result of the endeavour, that became more and more marked during the 2nd cent., after the adoption of current social usages and institutions, which necessarily led to a repression of the enthusiastic spirit out of which those offices had sprung and which could scarcely reconcile itself with what seemed to it worldly compromises and concessions. The fanatical and eccentric pretension to prophetic gifts in Montanism, with its uncompromising rigour (§ 40) and its withdrawal from church fellowship, gave to these charismatic offices their deadly blow. A further cause of their gradual decay may certainly be found in their relation to the growing episcopal hierarchy. At the time of the Didache, which knows nothing of a subordination of presbyters under the bishop (indeed like Phil. i. 1, it makes no mention of presbyters), this relation was one of thoroughly harmonious co-ordination and co-operation. In the 13th chap. the exhortation is given to choose only faithful and approved men as bishops and deacons, “for they too discharge for you τὴν λειτουργίαν τῶν προφητῶν καὶ διδασκάλων and so they represent along with those the τετιμημένοι among you.” The service of prophets, according to the Didache, was pre-eminently that of the ἀρχιερεῖς and so there was entrusted to them the consecration of the elements in the Lord’s Supper. This service the bishops and deacons discharged, inasmuch as, in addition to their own special duties as presidents of the congregation charged with its administration and discipline, they were required in the absence of prophets to conduct the worship. Then also they had to officiate as Teachers (1 Tim. v. 17) when occasion required and the necessary qualifications were possessed. But this peaceful co-operating of the two orders undoubtedly soon and often gave place to unseemly rivalry, and the hierarchical spirit obtruding itself in the _Protepiscopate_ (§ 17, 6), which first of all reduced its colleagues from their original equality to a position of subordination soon asserted itself over against the extraordinary offices which had held a place co-ordinate with and in the department of doctrine and worship even more authoritative and important than that of the bishops themselves. They were only too readily successful in having their usurpation of their offices
