The prophets did not speak at their own suggestion, but that, being organs of the Holy Spirit, they only uttered what they had been commissioned from heaven to declare. Whoever then wishes to profit in the Scriptures, let him, first of all, lay down this as a settled point, that the Law and the Prophets are not a doctrine delivered according to the will and pleasure of men, but dictated by the Holy Spirit. … We owe to the Scripture the same reverence which we owe to God; because it has proceeded from him alone, and has nothing belonging to man mixed with it.

—John Calvin
