Of course Jesus had himself had in his mind a comprehension both of what he was and of what he was doing which was luminous as the sun. But it was one of the most pathetic aspects of his earthly ministry that he could not tell all his mind to his followers. They were not able to bear it; they were too rude and limited to take it in. He had to carry his deepest thoughts out of the world with him unuttered, trusting with a sublime faith that the Holy Ghost would lead his Church to grasp them in the course of its subsequent development. Even what he did utter was very imperfectly understood. There was one mind, it is true, in the original apostolic circle of the finest quality and capable of soaring into the rarest altitudes of speculation. The words of Christ sank into the mind of John and, after lying there for half a century, grew up into the wonderful forms we inherit in his Gospel and Epistles. But even the mind of John was not equal to the exigency of the Church; it was too fine, mystical, unusual. His thoughts to this day remain the property only of the few finest minds. There was needed a thinker of broader and more massive make to sketch the first outlines of Christian doctrine; and he was found in Paul. 7. Paul was a born thinker. His mind was of majestic breadth and force. It was restlessly busy, never able to leave any object with which it had to deal until it had pursued it back to its remotest causes and forward into all its consequences. It was not enough for him to know that Christ was the Son of God: he had to unfold this statement into its elements and understand precisely what it meant. It was not enough for him to believe that Christ died for sin: he had to go farther and inquire why it was necessary that He should do so and how His death took sin away. But not only had he from nature this speculative gift: his talent was trained by education. The other apostles were unlettered men; but he enjoyed the fullest scholastic advantages of the period. In the rabbinical school he learned how to arrange and state and defend his ideas. We have the issue of all this in his Epistles, which contain the best explanation of Christianity possessed by the world. The right way to look at them is to regard them as the continuation of Christ's own teaching. They contain the thoughts which Christ carried away from the earth with him unuttered. Of course Jesus would have uttered them differently and far better. Paul's thoughts have everywhere the coloring of his own mental peculiarities. But the substance of them is what Christ's must have been if he had himself given them expression.
