Answer to the Letters of Petilian, the Donatist.
Chapter 15.—16. Look at the states of Musti and Assura:
Chapter 10.—23. Petilianus said: Did the apostle persecute any one? or did Christ betray any one?
Chapter 71.—157. Petilianus said: To you the prophet says, ‘Peace, peace and where is there peace?’
Chapter 24.—56. Petilianus said: "But you will answer that you abide by the same declaration, ‘He that is once washed needeth not save to wash his feet.’135 John xiii. 10. Now the ‘once’ is once that has authority, once that is confirmed by the truth."
57. Augustin answered: Baptism in the name of the Father and of the Son and of the Holy Ghost136 Matt. xxviii. 19. has Christ for its authority, not any man, whoever he may be; and Christ is the truth, not any man.
