"Validity" of inspired texts

What is important is the Church’s judgment on the contents of the work and the use which she has made of it. Does not the author of the Epistle to the Hebrews say in quoting a psalm of David: ‘But one in a certain place testified…’? thus showing to what extent the question of authorship is of secondary importance in the case of a text inspired by the Holy Spirit. What is true of Holy Scripture is also true of the theological tradition of the Church.
