Chapter 42.— 99.  Petilianus said:  "If Paul uttered these words to the unlearned and to the righteous, I say this to you who are unrighteous, Is Christ divided, that you should separate yourselves from the Church?" 100.  Augustin answered:  I am afraid lest any one should think that in this work of mine the writer has made a mistake, and has written the heading Petilianus said, when he ought to have written Augustin answered.   But I see what your object is:  you wished, as it were, to preoccupy the ground, lest we should bring those words in testimony against you.  But what have you really done, except to cause them to be quoted twice?  If, therefore, you are so much pleased with hearing the words which make against you, as to render it necessary that they should be repeated, hear, I pray you, these words as coming from me, Petilianus:  Is Christ divided, that you should separate yourselves from the Church?
