This action has been taken by some scholars—arguing from the premises of a later day—as evidence that Hippolytus made a retractation before his death. But Hippolytus was not the man to retract anything. And the Roman church of the next generation would never have allowed the erection of his statue if they had held him to be saved only by a deathbed repentance; still less would they have permitted the public and honourable inscription of the titles of works in which he glories in his conduct.[53] The church really acknowledged that both sides had made mistakes, and that Hippolytus’s errors—whatever they may have been—were due to an excess of zeal for righteousness and were not to be weighed against his consecrated learning and his burning devotion. THE APOSTOLIC TRADITION For a list and description of Hippolytus’s works reference must be made to the treatises on patrology; he was a prolific writer on exegetical, doctrinal and practical themes, who published at least fifty books and probably many more. But after he had been consecrated bishop of his separatist congregation, his first task was to provide treatises to perpetuate the principles for which he was contending so bitterly. One of these was _Of Gifts_, to which he alludes in 1. 1; it has not been preserved, although traces appear to be incorporated in Constitutions VIII, i-ii. And it was followed immediately by the Apostolic Tradition. Its introduction fixes its date and purpose. A “lapse or error” had “recently occurred” (1. 4), and Hippolytus undertakes to guard against its effects by setting forth the true doctrine “which has continued up to now”. And he recurs to the same theme at the close: “the many heresies have increased because their leaders would not learn the purpose of the apostles”, but “over all who hear the apostolic tradition and keep it, no heretics or any other man will prevail” (38. 2-3). The date accordingly must be close to 217 and the purpose is to cleave to the old ways, rejecting every innovation; the tradition which Hippolytus received from the presbyters before him (36. 12) must be maintained inviolate.
