Fifthly: The Apostle presents himself to us in these letters in the fullest outbursts of his heart. We have the whole man before us, intellectually, morally, and religiously. Probably no eight letters exist in all literature, from which it is possible to construct in equal fulness the mental portraiture of the writer. Nowhere can we find stronger bursts of feeling. He was a man of deep sensibility, united with the firmest resolve. His sacrifice of self, and complete freedom from all selfish aims, is exceeded by only one character in history. Who can read these letters through, and question the sincerity of the writer? Can any one believe that he was not true to his convictions, or that he was capable of deliberately stating what he knew to be false? If the facts were not as he has stated them, the only possible alternative is that he was the prey of an hallucination. Yet in every detail of business, and in disposing of all practical questions, his judgment was of the soundest character. There is one remarkable fact which these letters bring out distinctly, which is probably true of no other man that ever lived. The Apostle claimed to decide certain questions authoritatively in virtue of a divine guidance which he possessed. He gave that decision on two points, having the closest bearing on the daily life of the Christians of that day, and which excited deep conscientious scruples. These were: whether the obligation of observing certain days was binding on the Christian conscience, and whether it was unlawful to eat meat which had been offered in sacrifice to a heathen god. On each of these points he gives his own apostolical decision; yet in the very act of doing so, he directly enjoins that the conscientious scruples of those who could not acquiesce in it should be respected. Can this be said of any other man who thought that he possessed a supernatural guidance? Enthusiastic he was; but his was an enthusiasm which did not blind his judgment. He was a man, too, of a highly delicate mind, yet capable of using a refined sarcasm in dealing with his opponents. We have the whole man before us, and his entire character renders him a witness of the highest order.
