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.’ 2054 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 Ghost 2055 has Christ for its authority, not any man, whoever he may be; and Christ is the truth, not any man.
