36 And, O wretched heretic! You turn the weapons granted to the Church against the Synagogue, against belief in the Church's preaching, and distort against the common salvation of all the sure meaning of a saving doctrine. For you maintain by these words that Christ is a creature, instead of silencing the Jew, who denies that Christ was God before eternal ages, and that His power is active in all the working and teaching of God, by these words of the living Wisdom! For Wisdom has in this passage asserted that it had been created for the beginning of the ways of God and for His works from the commencement of the ages, lest perchance it might be supposed that it did not subsist before Mary; yet has not employed this word 'created' in order to signify that its birth was a creation, since it was created for the beginning of God's ways and for His works.
Nay rather lest any one should suppose that this beginning of the ways, which is indeed the starting-point for the human knowledge of things divine, was meant to subordinate an infinite birth to conditions of time, Wisdom declared itself established before the ages. For, since it is one thing to be created for the beginning of the ways and for the works of God, and another to be established before the ages, the establishing was intended to be understood as prior to the creation; and the very fact of its being established for God's works before the ages was intended to point to the mystery of the creation; since the establishing is before the ages, but the creation for the beginning of the ways and for the works of God is after the commencement of the ages.
