Chapter 75.— 165.  Petilianus said:  "O wretched traditors!   Thus indeed it was fitting that Scripture should be fulfilled.  But in you I grieve for this, that you have shown yourselves worthy to fulfill the part of wickedness." 166.  Augustin answered:  I might rather say, O wretched traditors! if I were minded, or rather if justice urged me to cast up against all of you the deeds of some among your number.  But as regards what bears on all of you, O wretched heretics, I on my part will quote the remainder of your words; for it is written, "There must be also heresies among you, that they which are approved may be made manifest among you." 2179   Therefore "it was fitting thus that Scripture should be fulfilled.  But in you I grieve for this, that you have shown yourselves worthy to fulfill the part of wickedness." 2179     1 Cor. xi. 19 .
