Chapter XXVII.

What Rule is to be observed in the Interpretation of Scripture.

[70.] But it will be said, If the words, the sentiments, the promises of Scripture, are appealed to by the Devil and his disciples, of whom some are false apostles, some false prophets and false teachers, and all without exception heretics, what are Catholics and the sons of Mother Church to do? How are they to distinguish truth from falsehood in the sacred Scriptures? They must be very careful to pursue that course which, in the beginning of this Commonitory, we said that holy and learned men had commended to us, that is to say, they must interpret the sacred Canon according to the traditions of the Universal Church and in keeping with the rules of Catholic doctrine, in which Catholic and Universal Church, moreover, they must follow universality, antiquity, consent. And if at any time a part opposes itself to the whole, novelty to antiquity, the dissent of one or a few who are in error to the consent of all or at all events of the great majority of Catholics, then they must prefer the soundness of the whole to the corruption of a part; in which same whole they must prefer the religion of antiquity to the profaneness of novelty; and in antiquity itself in like manner, to the temerity of one or of a very few they must prefer, first of all, the general decrees, if such there be, of a Universal Council, or if there be no such, then, what is next best, they must follow the consentient belief of many and great masters. Which rule having been faithfully, soberly, and scrupulously observed, we shall with little difficulty detect the noxious errors of heretics as they arise.
