Of the letters of the intermediate class, the first to the Thessalonians and that to the Philippians were by many rehabilitated as Pauline. The second to the Thessalonians was rejected with increasing confidence. A special problem was presented by the letters to the Colossians and Ephesians, both because of their evident mutual relationship and particularly in regard to certain parts of the Epistle to the Colossians which made a strong impression of genuineness. Holtzmann offered a solution which gave general satisfaction. He adopted the hypothesis that Colossians was based upon a genuine Pauline letter which had been worked over by a later hand._(_27_)_ The redactor he identified with the author of the Epistle to the Ephesians. While there was this general consensus in the critical camp, which was ratified in Holtzmann’s “Introduction,”_(_28_)_ the most diverse opinions on special points are found. Some attempts were made to save the [pg 027] genuineness of the second Epistle to the Thessalonians. For some, the Epistles to the Colossians and Ephesians are genuine throughout and represent a later phase of the Pauline theology. Nor were there lacking attempts of all kinds to rehabilitate the Pastoral Epistles. Those who did not venture to defend them as wholes make a point of retaining at least the “personal references.” The presentation of the Pauline teaching was, however, hardly affected by the literary divergences. Not even the most conservative of the critics had the boldness to place all the letters which have come down under the name of Paul on a footing of equality. Even those who regarded the Epistles to the Ephesians and Colossians as genuine did not fuse ideas of these Epistles with the system extracted from the four main Epistles, but presented them separately; and any who were not converted to the rejection of the Pastorals at all events took the precaution to give a separate chapter to the Pauline theology of these writings._(_29_)_ If only the personal references might be saved, these Epistles were as completely excluded from the presentation of the Pauline system as if they had been pronounced wholly spurious. Thus it continued to be the case, as it had been with Baur, that, generally speaking, only the four main epistles were taken into account in describing the Pauline system. The only significant change was that the epistle to the Philippians began to be put on the same footing, and, with a few exceptions, scholars no longer hesitated to regard as Pauline the conception of the pre-existence of Christ which is expressed in the section on the incarnation and obedience unto death. It was realised that the main epistles also presuppose this view, even if they do not state it so explicitly.
