Jesus Christ did not quote from the Scriptures because Moses and the prophets wrote them, or because they were revered by the Jews, or because they were the foundation of Judaism, or because men said they were holy, or because they were written in formal or impressive, religious language, or because they came in the form of a specially bound and crafted book, or for many other reasons. He quoted from the Scriptures because He knew the intrinsic Godly, spiritual Truth of them. They did not just make sense or accurately reflect preferred religious doctrine; they expressed infallible Truth.
