Although for the ordinary and regular communications from the divine Being to man the established priesthoods might suffice, yet occasions arise when there is need of a plenipotentiary with higher authority and more extensive powers. What is required of these exceptional ambassadors is not merely to repeat the doctrines of the old religion, but to establish a new one. In other words, they are the original founders of the great religions of the world. Of such founders there is but a very limited number. Beginning with China, and proceeding from East to West, we find six:— 1. CONFUCIUS, or KHUNG-FU-TSZE, the founder of Confucianism. 2. LAÒ-TSÉ, the founder of Taouism. 3. SAKYAMUNI, or GAUTAMA BUDDHA, the founder of Buddhism. 4. ZARATHUSTRA, or ZOROASTER, the founder of Parseeism. 5. MOHAMMED, or MAHOMET, the founder of Islamism. 6. JESUS CHRIST, the founder of Christianity. All these men, whom for convenience sake I propose to call _prophets_, occupy an entirely exceptional position in the history of the human race. The characteristics, or marks, by which they may be distinguished from other great men, are partly external, belonging to the views of others about them; partly internal, belonging to their own view about themselves. 1. The first external mark by which they are distinguished is, that within his own religion each of these is recognized as the highest known authority. They alone are thought of as having the right to change what is established. While all other teachers appeal to them for the sanction of their doctrines, there is no appeal from them to any one beyond. What they have said is final. They are in perfect possession of the truth. Others are in possession of it only in so far as they agree with them. No doubt, the sacred books are equally infallible with the prophets; but the sacred books of religions founded by prophets derive their authority in the last resort from them, and are always held to be only a written statement of their teaching. Thus, the sacred books of China are partly of direct Confucian authorship; partly by others who recognize him as their head. The only sacred book of the Tao-tsé is by their founder himself. The sacred books of the Buddhists are supposed discourses of the Buddha. The Avesta is the reputed work of Zarathustra. The Koran is the actual work of Mahomet. And lastly, the New Testament is all of it written in express subordination to the authority of Christ, to which it constantly appeals. These books, then, are infallible, because they contain the doctrines of their founders.
