Authenticity of the Bible
From the Catholic Encyclopedia
The authenticity or authority of Holy Writ is twofold on account of its twofold authorship. First, the various books which make up the Bible are authentic because they enjoy all the human authority that is naturally due to their respective authors. Second, they possess a higher authenticity, because invested with a Divine, supernatural authority through the Divine authorship which makes them the inspired word of God. Biblical authenticity in its first sense must naturally be considered in the articles on the several books of Sacred Scripture, in its second sense, it springs from Biblical inspiration, for which see INSPIRATION.
