14 Let Us explain briefly the nature and meaning of this lordship of Christ. It consists, We need scarcely say, in a threefold power which is essential to lordship. This is sufficiently clear from the scriptural testimony already adduced concerning the universal dominion of our Redeemer, and moreover it is a dogma of faith that Jesus Christ was given to man, not only as our Redeemer, but also as a law-giver, to whom obedience is due. Not only do the gospels tell us that he made laws, but they present him to us in the act of making them. Those who keep them show their love for their Divine Master, and he promises that they shall remain in his love. He claimed judicial power as received from his Father, when the Jews accused him of breaking the Sabbath by the miraculous cure of a sick man. "For neither doth the Father judge any man; but hath given all judgment to the Son." In this power is included the right of rewarding and punishing all men living, for this right is inseparable from that of judging. Executive power, too, belongs to Christ, for all must obey his commands; none may escape them, nor the sanctions he has imposed.
