Divine Authorship of Sacred Scripture

The Church receives the books of the Old and New Testaments as sacred and canonical because, written under the inspiration of the Holy Spirit, they have God as their author and were handed on to the Church as such. Divine authorship gives Scripture its unique authority as the Word of God in human words. The doctrine concerns the canonical writings themselves, not merely religious experiences behind them or a later community's judgment that they are spiritually useful.^[1]

God's authorship is principal and transcendent. He moves created agents according to their nature, so that his causality does not compete with the human writer as though each supplied a percentage of the text. The same written work is wholly from divine inspiration and genuinely from human composition at different orders of causality. This Catholic account avoids both a merely human Bible later approved by the Church and a divine text for which human history is an illusion.

Because God is author, the canon forms one ordered witness within the divine economy fulfilled in Christ. Divine intention can embrace relations and fulfilments that an individual sacred author did not foresee exhaustively, while never contradicting what the human author truly asserted. The Fuller Sense, typology, and canonical interpretation depend upon this unity but remain governed by the inspired text and Apostolic Tradition rather than by imaginative associations.^[3][4]

Divine authorship grounds Biblical Truth: whatever the inspired authors affirm is affirmed by the Holy Spirit. Determining that assertion requires attention to genre, idiom, context, rhetorical purpose, and historical conventions. God does not become the author of a modern scientific claim where the sacred writer makes none, nor may a real assertion be dismissed as a disposable human error simply because its theological implications are difficult.^[5]

Divine authorship belongs to every canonical book with all its parts as received by the Church. It does not attach in descending degrees according to a book's liturgical frequency, devotional popularity, or apparent doctrinal importance. The Gospels have a preeminent place because they principally witness to the incarnate Word, yet Romans, Tobit, James, and Revelation are not less inspired. The Hierarchy of Truths orders doctrines by relation, not scriptural books by percentages of divine origin.

The Church recognizes rather than creates this authorship. Historical criteria such as apostolic connection, conformity to the Rule of Faith, and liturgical use participated in canonical discernment, but inspiration originates in God's action. Later translations, copies, lectionaries, and critical editions transmit the inspired writings without each becoming a newly inspired composition. Their authority depends on faithful relation to the canonical text and ecclesial approval for the use claimed.
