Chapter 66.— 147.  Petilianus said:  "‘Blessed are they which do hunger and thirst after righteousness:  for they shall be filled.’  To you it seems to be righteousness that you thirst after our blood." 148.  Augustin answered:  What shall I say unto thee, O man, except that thou art calumnious?  The unity of Christ, indeed, is hungering and thirsting after all of you; and I would that it might swallow you up, for then would you be no longer heretics.
