8 Since, therefore, their Triacontad is thus brought to nought, as I have shown, both with respect to defect and excess (for in dealing with such a number, either excess or defect [to any extent] will render the number untenable, and how much more so great variations?), it follows that what they maintain respecting their Ogdoad and Duodecad is a mere fable which cannot stand. Their whole system, moreover, falls to the ground, when their very foundation is destroyed and dissolved into Bythus, that is, into what has no existence. Let them, then, henceforth seek to set forth some other reasons why the Lord came to be baptized at the age of thirty years, and [explain in some other way] the Duodecad of the apostles; and [the fact stated regarding] her who suffered from an issue of blood; and all the other points respecting which they so madly labour in vain.
