CHAPTER III: THE SOVEREIGN LORDSHIP OF JESUS CHRIST OVER EVERY SOCIETY AND EVERY NATION
T. You recollect the second article of the Creed? "I believe in Jesus Christ our Lord." And in the Credo at Mass we say: "I believe in one Lord, Jesus Christ, the only-begotten Son of God ... God of God ... Who for us men and for our salvation was incarnate by the Holy Ghost of the Virgin Mary and was made Man."
S. As we are speaking of things social, may I ask if there is a special relationship between the sacred humanity of Jesus Christ and the social order established in the world?
T. Undoubtedly there must be. Man is so created that he is made for social life. By his nature and the conditions of his existence he is called to live in society. Jesus Christ became Man to bring man to his eternal supernatural happiness. The Divine Redeemer must then have a positive influence on all those conditions through which He must guide man to his end. But man, being made for society, must tend towards his end as a social being, that is to say, he must tend thereunto by means of that society for which he is made. This society cannot be a final end but only a means. To be a means, it must be sanctified and sanctifying. This can only be obtained in Christ and through His Sacred Humanity. Thus it is clear that there must be a special relation between the Sacred Humanity of Christ and the social order established in the world.
S. I follow you so far, but why speak of Jesus Christ specially? Is He not God and does not all that is said of God apply to Him?
T. Certainly all that is said of God applies to the Eternal Word made Man for us. Jesus Christ is God: every society therefore depends on Him with a sovereign and absolute dependence. But we must always remember that in Jesus Christ there is but one Person and two natures, the Person of the Word; the divine and the human nature.
The Person of the Word of God has assumed human nature and united it hypostatically to Himself. Thus the human nature of Christ subsists only in the Word. In Jesus Christ human nature is endowed with altogether special qualities, is clothed with altogether special conditions.
S. May I hear what are the special conditions attaching to the Sacred Humanity of Christ by the dignity accruing to it from the hypostatic union?
T. The actions of Christ are theandric, that is to say, actions of God in a human nature. This is a consequence of the fact that actions are always. attributed to the person performing them. As in Jesus Christ there is only one, person, not two persons, all the acts of Christ's human nature are imputed to the Divine Person.
S. Now, then, explain the Redemption? Is not Jesus Christ at the same time our Redeemer?
T. Jesus Christ is our Redeemer. He redeemed the human race through His human nature. It is in this nature that He is priest and mediator between the Blessed Trinity and mankind. As man He is also King of the human race. To understand the special powers and mission with which Jesus Christ as Man is divinely endowed, we must not lose sight of the conditions attaching to the Divine Master on account of His quality of Man-Mediator. He is truly Man, He is truly God. As God He depends upon nobody. He can receive nothing from anybody, and all things depend on Him. As Man He has, like every other creature, to receive everything from God, but under special conditions.
