Chapter I.--That the Scriptures are Divinely Inspired.
1. But as it is not sufficient, in the discussion of matters of such importance, to entrust the decision to the human senses and to the human understanding, and to pronounce on things invisible as if they were seen by us,  we must, in order to establish the positions which we have laid down, adduce the testimony of Holy Scripture. And that this testimony may produce a sure and unhesitating belief, either with regard to what we have still to advance, or to what has been already stated, it seems necessary to show, in the first place, that the Scriptures themselves are divine, i.e., were inspired by the Spirit of God. We shall therefore with all possible brevity draw forth from the Holy Scriptures themselves, such evidence on this point as may produce upon us a suitable impression, (making our quotations) from Moses, the first legislator of the Hebrew nation, and from the words of Jesus Christ, the Author and Chief of the Christian religious system. 
 Visibiliter de invisibilibus pronunciare.
 Principis Christianorum religionis et dogmatis.
