It was evidently, therefore, for the information of orthodox persons that our MS. was made, but not for that of the orthodox public generally, whether clerical or lay. Had it been so, it would have been weighted with a running commentary casting scorn upon its erroneous doctrines, or by so-called refutations like those which encumber the pages of heresiologists such as Irenæus, Hippolytus, and Epiphanius. Had it been written by an ecclesiastic, moreover, it would certainly have borne some preface, or colophon, as does the _Philosophumena_, claiming merit for, and giving the date of the completion of the work.[48] Yet there is nothing in the present text to show that it was written by an ecclesiastic of any kind, while it follows from what has been said above that it was begun by a scribe who took unusual pains to ensure an accurate copy, and that when he handed over for a time the continuation of his work to a subordinate, he yet went over and corrected the latter’s work with as much care as he bestowed upon his own. All this suggests that it was made for official or judicial use; and the most reasonable guess is that it was the draft or copy of a legal document made for the enlightenment of some conciliar, episcopal, or even secular tribunal concerned in the suppression of heresy, such as the Inquisitors of the Faith set up by Theodosius. This would solve the problem which has so vexed the minds of commentators like Prof. Harnack and Dr. Schmidt as to the occurrence of the colophon “Part of the Books of the Saviour” at the foot of the Second and Third Documents. It is natural enough that the second or subaltern scribe, continuing the work of which only the first part was once thought sufficient, should preface the continuation by the title “The Second Tome of Pistis Sophia”; but that as he completed the copying of each subsequent extract stichometrically arranged, should add the words: “Part of the Books of the Saviour” to indicate the collection of MSS., probably seized in a raid by the Imperial authorities on some heretic’s library, from which they were all taken.
