Though Origen was the first great interpreter of Scripture in the Church, commentaries had been written before his. He speaks of those who had preceded him in this activity; and though but little survives of the labours of these earlier expositors, we know that the work of commenting on Scripture was zealously carried on in the Gnostic churches in the latter part of the second century, and several of the older exegetes in the Church are also known to us by name and reputation. Heracleon the Gnostic commentator on John, who is often cited and often rather unfairly dealt with by Origen, as he follows him over the same ground, belonged to the Valentinian school. Many of his comments the reader will find to be very just and shrewd; but the tenets of his school led him into many extravagances. Of Pantænus, head of the catechetical school at Alexandria in the end of the second and early years of the third century, we hear that he interpreted many of the books of Scripture. We also learn that he preceded Clement and Origen, his successors in office, in the application of Gentile learning to Christian studies; the broad and liberal tone of Alexandrian theology may be due in part to his influence. Much of his exegetical work was still extant in the days of Jerome, who, however, reports that he did more for the Church as a teacher than as a writer. Only fragments of his Commentaries now remain. In Clement’s works, on the contrary, we find, if not any set commentaries, various extended discussions of particular texts. We also find in him a theory of Scripture, its inspiration and its nature, which is followed also by Origen, and which determines the whole character of Alexandrian exegesis. In accordance with the general tendency of that age, which witnessed a reaction from the independence of philosophy and an appeal in many quarters to the authority of ancient oracles and writings, the Alexandrian school treats Scripture as an inspired and infallible storehouse of truth,—of truth, however, not patent to the simple reader, but requiring the spiritual man to discern its mystic import. Clement discusses the question why divine things are wrapped up in mysteries, and holds that all who have spoken of such things have dealt with them in this way. Everything in Scripture, therefore, has a mystical in addition to its obvious meaning. Every minute particular about the tabernacle and its furniture is charged with an unseen truth. The effect of such a view of Scripture on exegesis is necessarily that the interpreter finds in the inspired words not what they plainly convey, but what most interests his own mind. In assigning to each verse its spiritual meaning, he is neither guided nor restrained by any rule or system, but enjoys complete liberty. The natural good sense of these great scholars curbed to some extent the licence of their theory; but with such a view of Scripture they could not but run into many an extravagance; and the allegorical method of interpretation, which so long prevailed in Christendom and is still practised in some quarters, dates from Alexandria. The roots of it lie further back, in Jewish rabbinical treatment of the Old Testament, and in the Greek philosophy of Alexandria. In Philo, the great contemporary of Christ at Alexandria, rabbinical and Greek learning met, and Scripture being a divine authority and having to furnish evidence of Greek philosophical doctrines, the allegorical method of interpretation was called to perform large services. To Philo’s eyes all wisdom was contained in the Pentateuch, and many an idea of which Moses never dreamed had to be extracted from that ancient record. The method was older than Clement and Origen, but it was through them that it became so firmly established in the Church.
