You may have also another image of what has been said, in Thamar sitting by the way, and presenting the appearance of a harlot, on whom the studious Judas (whose name is interpreted “powerful”), who left nothing unexamined and uninvestigated, looked; and turned aside to her, preserving his profession towards God. Wherefore also, when Sarah was jealous at Hagar being preferred to her, Abraham, as choosing only what was profitable in secular philosophy, said, “Behold, thy maid is in thine hands: deal with her as it pleases thee;” manifestly meaning, “I embrace secular culture as youthful, and a handmaid; but thy knowledge I honour and reverence as true wife.” And Sarah afflicted her; which is equivalent to corrected and admonished her. It has therefore been well said, “My son, despise not thou the correction of God; nor faint when thou art rebuked of Him. For whom the Lord loveth He chasteneth, and scourgeth every son whom He receiveth.” And the foresaid Scriptures, when examined in other places, will be seen to exhibit other mysteries. We merely therefore assert here, that philosophy is characterized by investigation into truth and the nature of things (this is the truth of which the Lord Himself said, “I am the truth”); and that, again, the preparatory training for rest in Christ exercises the mind, rouses the intelligence, and begets an inquiring shrewdness, by means of the true philosophy, which the initiated possess, having found it, or rather received it, from the truth itself.
