There are three analogies(104) which illustrate this creation of our Lord--a creation in itself as singular as His assumption of man's nature.
First, that of the relation between the soul and body. The soul is the life of the body; the body, as it were, the mansion and home of the soul, its bearer. Through the body the qualities of the soul become visible and known; its powers exercise themselves, and personal unity so binds the two together that we love or hate, admire or despise, the one for the sake of the other; the grief of the soul acts upon the body, the sickness of the body depresses the soul. Through the acts of the body we learn the very existence of the soul, and in these acts it portrays itself. Human nature has been so made by its Creator that the qualities of soul and body, of spirit and matter, are imputed in the individual man to each other. Now to the Body we have been considering the Spirit of Christ is, as it were, the soul. It is nothing strange, then, if it was His will to create such a Body, if it be the result of His Incarnation, that the like effects which exist in the case of every human soul and body should take place here. To this Body also the power and virtue of its soul are communicated; and, since Christ by His Spirit animates it, in honouring it He is honoured; in despising it, He is despised. There is an imparting to it of the qualities which He has; and thus it is that unity and sanctity, truth and charity dwell in it as the operation of His mind. Thus every man contains in himself, in the union of soul and body, an image of that tie by which Christ and His Church are one.
Secondly, because God has created man for society, He has implanted in him an irrepressible instinct of communion with his brother men. This instinct it is which, under circumstances of every possible variety, results in one end, the State. The human commonwealth, whatever external shape it wear, whatever division of its powers it make, springs from this. In virtue of this original formation of man, that he is made to live together, and gregariously, not separately, the supreme power of government, the power of life and death, dwells in the community, and obedience to it has a divine sanction. Thus, the commonwealth has a variety of powers which the individual has not, and not only so, but it also has powers which do not arise from the mere aggregation of individuals, rather which belong to it as a community, as a whole, for instance, sovereignty in all the details of its exercise. But now the very object for which Christ became Incarnate was to constitute a divine commonwealth. He is the King: it is the tenderness of a God Incarnate that He calls and makes His Kingdom His Body. The powers, then, which belong to the earthly commonwealth belong, with the changes which the change of subject carries, to the Divine. They who have so great a reverence for human government, who respect in the nation an ultimate irresponsible power, ought, if they were consistent, when they acknowledge Christ as having come in the flesh, to acknowledge His government in the kingdom which He has set up. All that his country is to the patriot, the Church is to the Christian, but in so much higher a degree, as the object for which Christ came is above the needs and cares of this present life. Has the City of God, then, less claim upon Christians than the City of Romulus had upon Romans? Thus, in the natural duty of the citizen, as well as in the compound nature of man, is contained a reminder of the Christian's relation to the Church, and a picture and ensample of the Church's authority.
