Chapter 83.— 181.  Petilianus said:  "If then there are not some to whom all this power of faith is found to be in opposition, on what principle do you persecute, so as to compel men to defile themselves:?" 182.  Augustin answered:  We neither persecute you, except so far as truth persecutes falsehood; nor has it anything to do with us if any one has persecuted you in other ways, just as it has nothing to do with you if any of your party do likewise; nor do we compel you to defile yourselves, but we persuade you to be cured.
