In their search for an explanation as to how God could have allowed his "son" to be executed, they fell upon the theory that Christ's death was a sacrifice for their sins, an expiation for their guilt. From that time on, says Nietzsche, "there was gradually imported into the type of the Saviour the doctrine of the Last Judgment, and of the 'second coming,' the doctrine of sacrificial death, and the doctrine of _Resurrection,_ by means of which the whole concept 'blessedness,' the entire and only reality of the gospel, is conjured away--in favour of a state _after_ death." St. Paul then rationalised the conception by introducing into it the doctrine of personal immortality by means of having Christ rise from the dead; and he preached this immortality as a reward for virtue. Thus, asserts Nietzsche, Christ's effort toward a Buddhistic movement of peace, "toward real and _not_ merely promised _happiness on earth"_ was controverted by his posterity. Nothing of Christ's original doctrine remained, once Paul, the forger, set to work to twist it to his own ends. Paul went further and by changing and falsifying it turned all Jewish history into a _prophecy_ for his own teachings. Thus the whole doctrine of Christ, the true meaning of his death and the realities which he taught, were altered and distorted. In short, Christ's life was used as a means for furthering the religion of Paul, who gave to it the name of Christianity. A most important part of "The Antichrist" is that passage wherein Nietzsche defines his order of castes. Every healthy society, says he, falls naturally into three separate and distinct types. These classes condition one another and "gravitate differently in the psychological sense." Each type has its own work, its own duties, its own emotions, its own compensations and mastership. The first class, comprising the rulers, is distinguished by its intellectual superiority. It devolves upon this class "to represent happiness, beauty and goodness on earth." The members of this superior class are in the minority, but they are nevertheless the creators of values. "Their delight is self-mastery: with them asceticism becomes a second nature, a need, an instinct. They regard a difficult task as their privilege; to play with burdens which crush their fellows is to them a _recreation."_ They are at once the most honourable, cheerful and gracious of all men. The second class is composed of those who relieve the first class of their duties and execute the will of the rulers. They are the guardians of the law, the merchants and professional men, the warriors and the judges. In brief, they are the executors of the race. The third class is made up of the workers, the lowest order of man--those destined for menial and disagreeable tasks. "The fact," says Nietzsche, "that one is publicly useful, a wheel, a function, presupposes a certain natural destiny: it is not _society,_ but the only kind of _happiness_ of which the great
