So when those on whose authority I have consented to believe in the gospel tell me not to believe in Manichæus, how can I but consent? Take your choice. If you say, Believe the Catholics: their advice to me is to put no faith in you; so that, believing them, I am precluded from believing you; -- If you say, Do not believe the Catholics: you cannot fairly use the gospel in bringing me to faith in Manichæus; for it was at the command of the Catholics that I believed the gospel; -- Again, if you say, You were right in believing the Catholics when they praised the gospel, but wrong in believing their vituperation of Manichæus: do you think me such a fool as to believe or not to believe as you like or dislike, without any reason? It is therefore fairer and safer by far for me, having in one instance put faith in the Catholics, not to go over to you, till, instead of bidding me believe, you make me understand something in the clearest and most open manner. To convince me, then, you must put aside the gospel. If you keep to the gospel, I will keep to those who commanded me to believe the gospel; and, in obedience to them, I will not believe you at all. But if haply you should succeed in finding in the gospel an incontrovertible testimony to the apostleship of Manichæus, you will weaken my regard for the authority of the Catholics who bid me not to believe you; and the effect of that will be, that I shall no longer be able to believe the gospel either, for it was through the Catholics that I got my faith in it; and so, whatever you bring from the gospel will no longer have any weight with me. Wherefore, if no clear proof of the apostleship of Manichæus is found in the gospel, I will believe the Catholics rather than you. But if you read thence some passage clearly in favor of Manichæus, I will believe neither them nor you: not them, for they lied to me about you; nor you, for you quote to me that Scripture which I had believed on the authority of those liars. But far be it that I should not believe the gospel; for believing it, I find no way of believing you too. For the names of the apostles, as there recorded,  do not include the name of Manichæus. And who the successor of Christ's betrayer was we read in the Acts of the Apostles;  which book I must needs believe if I believe the gospel, since both writings alike Catholic authority commends to me. The same book contains the well-known narrative of the calling and apostleship of Paul.  Read me now, if you can, in the gospel where Manichæus is called an apostle, or in any other book in which I have professed to believe. Will you read the passage where the Lord promised the Holy Spirit as a Paraclete, to the apostles? Concerning which passage, behold how many and how great are the things that restrain and deter me from believing in Manichæus.
