a criterion in the discovery of things. What is suhjected to criticism is not believed till it is so subjected; so that what needs criticism cannot be a first principle. Therefore, as is reasonable, grasping by faith the indemonstrable first principle, and receiving in abundance, from the first principle itself, demonstrations in reference to the first principle, we are by the voice of the Lord trained up to the knowledge of the truth.
For we may not give our adhesion to men on a bare statement by them, who might equally state the opposite. But if it is not enough merely to state the opinion, but if what is stated must be confirmed, we do not wait for the testimony of men, but we establish the matter that is in question by the voice of the Lord, wdiich is the surest of all demonstrations, or rather is the only demonstration; in which knowledge those who have merely tasted the Scriptures are believers; while those who, having advanced further, and become correct expounders of the truth, are Gnostics.
