8 After this preliminary account of St. Jerome's life and labors we may now treat of his teaching on the divine dignity and absolute truth of Scripture. You will not find a page in his writings which does not show clearly that he, in common with the whole Catholic Church, firmly and consistently held that the Sacred Books - written as they were under the inspiration of the Holy Spirit - have God for their Author, and as such were delivered to the Church. Thus he asserts that the Books of the Bible were composed at the inspiration, or suggestion, or even at the dictation of the Holy Spirit; even that they were written and edited by Him. Yet he never questions but that the individual authors of these Books worked in full freedom under the Divine afflatus, each of them in accordance with his individual nature and character. Thus he is not merely content to affirm as a general principle - what indeed pertains to all the sacred writers - that they followed the Spirit of God as they wrote, in such sort that God is the principal cause of all that Scripture means and says; but he also accurately describes what pertains to each individual writer. In each case Jerome shows us how, in composition, in language, in style and mode of expression, each of them uses his own gifts and powers; hence he is able to portray and describe for us their individual character, almost their very features; this is especially so in his treatment of the Prophets and of St. Paul. This partnership of God and man in the production of a work in common Jerome illustrates by the case of a workman who uses instruments for the production of his work; for he says that whatsoever the sacred authors say "Is the word of God, and not their own; and what the Lord says by their mouths He says, as it were, by means of an instrument."
