Why different testaments and books in the Word?
“As regards the Word particularly, it has existed in every age, though not the Word we possess at the present day. Another Word existed in the Most Ancient Church before the Flood, and yet another Word in the Ancient Church after the Flood. Then came the Word written through Moses and the Prophets in the Jewish Church, and finally the Word written through the Evangelists in the new Church. The reason why the Word has existed in every age is that by means of the Word there is a communication between heaven and earth, and also that the Word deals with goodness and truth, by which a person is enabled to live in eternal happiness. In the internal sense therefore the Lord alone is the subject, for all goodness and truth are derived from Him” (Arcana Coelestia n. 2895).
