20 Let him further go on, in his discourse of many but manifestly empty words, to matters of which he is wholly ignorant, or in which rather he abuses the ignorance of the mass of those who hear him, and from the confession of a certain woman, that she had called herself a catechumen of the Manichæans, being already a full member of the Catholic Church, let him say or write what he pleases concerning their baptism—not knowing, or pretending not to know, that the name of catechumen is not bestowed among them upon persons to denote that they are at some future time to be baptized, but that this name is given to such as are also called Hearers, on the supposition that they cannot observe what are considered the higher and greater commandments, which are observed by those whom they think right to distinguish and honor by the name of Elect.
Let him also maintain with wonderful rashness, either as himself deceived or as seeking to deceive, that I was a presbyter among the Manichæans. Let him set forth and refute, in whatever sense seems good to him, the words of the third book of my Confessions, which, both in themselves, and from much that I have said before and since, are perfectly clear to all who read them. Lastly, let him triumph in my stealing his words, because I have suppressed two of them, as though the victory were his upon their restoration.
