The doctrine of Jesus, like all religious doctrines, is regarded in two ways,--first, as a moral and ethical system which teaches men how they should live as individuals, and in relation to each other; second, as a metaphysical theory which explains why men should live in a given manner and not otherwise. One necessitates the other. Man should live in this manner because such is his destiny; or, man's destiny is this way, and consequently he should follow it. These two methods of doctrinal expression are common to all the religions of the world, to the religion of the Brahmins, to that of Confucius, to that of Buddha, to that of Moses, and to that of the Christ. But, with regard to the doctrine of Jesus, as with regard to all other doctrines, men wander from its precepts, and they always find some one to justify their deviations. Those who, as Jesus said, sit in Moses' seat, explain the metaphysical theory in such a way that the ethical prescriptions of the doctrine cease to be regarded as obligatory, and are replaced by external forms of worship, by ceremonial. This is a condition common to all religions, but, to me, it seems that it never has been manifested with so much pomp as in connection with Christianity,--and for two reasons: first, because the doctrine of Jesus is the most elevated of all doctrines (the most elevated because the metaphysical and ethical portions are so closely united that one cannot be separated from the other without destroying the vitality of the whole); second, because the doctrine of Jesus is in itself a protest against all forms, a negation not only of Jewish ceremonial, but of all exterior rites of worship. Therefore, the arbitrary separation of the metaphysical and ethical aspects of Christianity entirely disfigures the doctrine, and deprives it of every sort of meaning. The separation began with the preaching of Paul, who knew but imperfectly the ethical doctrine set forth in the Gospel of Matthew, and who preached a metaphysico-cabalistic theory entirely foreign to the doctrine of Jesus; and this theory was perfected under Constantine, when the existing pagan social organization was proclaimed Christian simply by covering it with the mantle of Christianity. After Constantine, that arch-pagan, whom the Church in spite of all his crimes and vices admits to the category of the saints, after Constantine began the domination of the councils, and the centre of gravity of Christianity was permanently displaced till only the metaphysical portion was left in view. And this metaphysical theory with its accompanying ceremonial deviated more and more from its true and primitive meaning, until it has reached its present stage of development, as a doctrine which explains the mysteries of a celestial life beyond the comprehension of human reason, and, with all its complicated formulas, gives no religious guidance whatever with regard to the regulation of this earthly life.
