The inspiration of the Sacred Text offers an analogy to that of the artist musician. The divine melody of truths and facts is definitely communicated to the inspired composer of the Sacred Books. Sometimes he sings loud and with strong emphasis, sometimes he barely breathes his heavenly tones, yet they are no uncertain notes; they allow of no alteration, addition, or omission. But in the accompanying chords he takes now one set, now another, remaining in the same clef, ever true to the melody, yet manifold in the variety of expressing that truth. Even the seeming discords, which, taken by themselves, look like errors, prove to be part of the great theme; when rightly understood they are but transition chords which prepare us for the complete realization of the succeeding harmony into which they resolve themselves.
Does the Church indorse the definition of Scriptural inspiration which has been given in the two preceding chapters? The Church has said very little on the subject of the inspiration of the Sacred Scriptures, but enough to serve us as a definition and as an expression of its limitations. The Councils of Florence and Trent simply state that "the Sacred Scriptures, having been written under the inspiration of the Holy Ghost, have God for their author." How much may be deduced from this was made clear by the late Vatican Council (Constit., _de Fide_, cap. ii.), which holds that "the Church regards these books (enumerated in the Tridentine Canon), as sacred and canonical, not because, having been composed through the care and industry of men, they were afterwards approved by the authority of the Church, nor simply because they contain revealed truth without error, but because they were written under the inspiration of the Holy Ghost in such a way as to have God for their author...."[1]
By this definition two distinct theories of inspiration are censured as contrary to Catholic teaching. The first is that which has been called _subsequent_ inspiration, according to which a book might be written wholly through human industry, but receiving afterwards the testimony of express divine approval, might become the written word of God. This teaching is not admissible inasmuch as it excludes the divine authorship of the Scriptures.
