The Priest ... appears on the scene at a time when Prophecy has already succeeded in hewing out a path for its Idea; when that Idea has already had a certain effect on the trend of society, and has brought about a new harmony or balance be tween the different forces at work. The Priest also fosters the Idea, and desires to perpetuate it; but he is not of the race of giants. He has not the strength to fight continually against necessity and actuality; his tendency is rather to bow to the one and come to terms with the other. Instead of clinging to the narrowness of the Prophet, and demanding of reality what it cannot give, he broadens his outlook, and takes a wider view of the relation between his Idea and the facts of life. Not what to be, but what be, is what he seeks. His watchword is not the Idea, the whole Idea, and nothing but the Idea; he accepts the complex "harmony" which has resulted from the conflict of that Idea with other forces. His battle is no longer a battle against actuality, but a battle in the name of actuality against its enemies.
