In brief, Kierkegaard held a fascination with this topic since he was concerned with inspiration, authority and the pastor's vocation. To make matters worse, he later recanted, claiming that his work was a work of genius. Kierkegaard asserted that Adler confused the categories of genius and inspiration. Kierkegaard regarded it as thoughtless to call St. Paul a genius if he was divinely inspired, that is, spoke with authority. Simply put, he did not consider himself a true Christian, nor to possess authority.
Authority is the decisive quality.
One cannot intellectually approach the claims of Christ. They must be appropriated by faith since they are not open to empirical scrutiny. The esthetician wants to relate to the Gospel without the miraculous. He cannot see the divine inspiration of the New Testament writers.
