The Refutation of All Heresies: Book IV. 45Use of the Foregoing Discussions.

It appears, then, that these speculations also have been sufficiently explained by us. But since I think that I have omitted no opinion found in this earthly and grovelling Wisdom, I perceive that the solicitude expended by us on these subjects has not been useless. For we observe that our discourse has been serviceable not only for a refutation of heresies, but also in reference to those who entertain these opinions. Now these, when they encounter the extreme care evinced by us, will even be struck with admiration of our earnestness, and will not despise our industry and condemn Christians as fools when they discern the opinions to which they themselves have stupidly accorded their belief. And furthermore, those who, desirous of learning, addict themselves to the truth, will be assisted by our discourse to become, when they have learned the fundamental principles of the heresies, more intelligent not only for the easy refutation of those who have attempted to deceive them, but that also, when they have ascertained the avowed opinions of the wise men, and have been made acquainted with them, that they shall neither be confused by them as ignorant persons would, nor become the dupes of certain individuals acting as if from some authority; nay, more than this, they shall be on their guard against those that are allowing themselves to become victims to these delusions.
