The Instructor (ὁ παιδαγωγός, or, as Eusebius calls it here, τρεῖς τε οι τοῦ ἐπιγεγραμμένου παιδαγωγοῦ), is likewise extant, in three books. The work is chiefly of a moral and practical character, designed to furnish the new convert with rules for the proper conduct of his life over against the prevailing immoralities of the heathen. Its date is approximately fixed by the fact that it was written after the Exhortation to which it refers, and before the Stromata, which refers to it (see Strom. VI. 1).
