352. The Teaching of Christ on the Three Classes of Precepts: Moral, Ceremonial and Judicial.—(a) As regards the moral precepts (i.e., the Decalogue or Natural Law), not one jot or tittle was to pass away. But so little was the soul of these precepts then recognized that Christ gave a new commandment of love, by which His followers were to be known; and He reduced the whole law to the two commandments of love of God and love of our neighbor.
(b) As regards the ceremonial precepts (i.e., the forms of Jewish worship), these were to be superseded. Christ declared the manner in which God was to be worshipped, namely, in spirit and in truth. He instituted the Sacrifice of the New Testament, appointed the ritual of the Sacraments (e.g., of Baptism and the Eucharist), and taught a form of prayer which was to be used by His disciples. Other things He left to be determined by the Church.
(c) As regards the judicial precepts (i.e., the civil laws of the theocratic nation), these ceased to be necessary with the coming of Christ, whose Kingdom is spiritual and with whom there is no distinction of Jew or Gentile, since His law is for all. In fact, with the destruction of Jerusalem in A.D. 70, foretold by Christ, both the Temple worship and the separate national life of Israel came to an end. In correcting the false interpretations which the Pharisees put upon various judicial precepts of their law (e.g., in showing them that the law of retaliation and the law that public enemies should be put to death did not authorize revenge and hatred), Christ indicated the spirit that should animate all civil laws, namely, love of justice. He left it to the wisdom of future lawgivers to apply the rule of justice to the relations between man and man, nation and nation, as circumstances would require.
353. The precepts by which Christ established the primacy of the Pope and the hierarchy may be called judicial. But the details of this constitution He left the Church to determine.
354. The Duration of the Law of Christ.—(a) The Beginning.—The New Law was given through the revelation made by Christ and the Holy Ghost to the Apostles; it was ratified at the Last Supper and in the death of Christ, when the New Testament was proclaimed and the Old Testament came to an end; it was promulgated, first at Jerusalem on the day of Pentecost, and later throughout the world by the preaching of the Apostles.
(b) The End.—The Law of Christ continues till the end of time; for this generation—that is, this last period of world history under the Christian dispensation—shall not end until Christ returns to judge mankind; “Behold, I am with you all days, even unto the consummation of the world” (Matt., xxviii. 20).
355. The Subjects of the Law of Christ.—(a) The Law of Christ is for all: “Going, therefore, teach ye all nations. teaching them to observe all things whatsoever I have commanded you” (Matt., xxviii. 19).
(b) The Law of Christ does not oblige all in the same way. Those outside Christianity are obliged directly by the commands to believe and to be baptized. Christians are obliged directly by the laws of faith and works accepted in Baptism.
356. Ignorance of the Law of Christ.-(a) Outsiders may be in invincible ignorance of the Law of Christ. For many persons through no fault of their own, in times past or even today, have not heard the Gospel message: “How shall they believe Him of whom they have not heard?” (Rom, x. 14).
(b) Christians may be in invincible ignorance of the Law of Christ. For, just as want of a preacher causes a pagan to be invincibly ignorant of the necessity of Baptism, so a lack of instruction in Christian doctrine might leave a baptized person inculpably ignorant (e.g., of the duty of receiving the Eucharist).
