of true and false Teachers.

explain, so that from this matter, which is our primary proposition, we may finally prove that neither true teachers nor true doctrine are found in any assembly of Sectarians heretical groups. For when I say that someone is placed by God to teach, I include two things. The first is that he has received the authority to teach from God himself, either by the ordinary way, which is contained in some approval (at least tacit) of the ministers of the Church who succeed the Apostles, or certainly by an extraordinary way (which we shall show is also lacking in the Sectarians). The second (in which there is a certain primary force, as we shall see, and which follows from the first) is that he has such weight in authority, and is so fortified with those defenses that are wont to merit the faith and assent of men, that even those who cannot sufficiently judge and comprehend the truth of the doctrine itself by themselves can prudently and must assent to him rather than to another who teaches differently about religion. This is the power and reason of a teacher placed by God to teach. For first, those who set themselves over the office of teaching without divine disposition, they teach only in the "chair of pestilence" (says the blessed Cyprian), which God did not constitute, but which they themselves erected, from which their Book on the Unity of the Church.
