Man lives not as body alone, nor as soul alone, but as the union of the two, in reciprocal commerce. Soul and body are distinct, but not separate. Each has its own distinctive properties and functions, and neither can replace the other; but their separation is death, the death of the body only, not of the soul indeed, for that is immortal. The body is material, and, separated from the soul, is dust and ashes, mere slime of the earth, from which it was formed. It is the same in the moral order with society, which is not state alone, nor church alone, but the union of the two in reciprocal commerce. The two are distinct, each has its distinctive nature, laws, and functions, and neither can perform the functions of the other, or take the other's place. But though distinct, they cannot in the normal state of society be separated. The separation of the state from the church is in the moral order what the separation of the body from the soul is in the physical order. It is death, the death of the state, not indeed of the church; for she, like the soul, nay, like God himself, is immortal. The separation of the state from the church destroys its moral life, and leaves society to become a mass of moral rottenness and corruption. Hence, the holy father includes the proposition to separate church and state, in his syllabus of condemned propositions. The soul is defined by the church as the _forma corporis_, the informing or vital principle of the body. The church in the moral order is _forma civitatis_, the informing, the vital principle of the state or civil society, which has no moral life of its own, since all moral life, by its very term, proceeds from the spiritual order. There is in the physical order no existence, but from God through the medium of his creative act; so is there no moral life in society, but from the spiritual order which is founded by God as supreme law-giver, and represented by the church, the guardian and judge alike of the natural law and the revealed law. The soul is the nobler and superior part of man, and it belongs to it, not to make away with the body, or to assume its functions, but to exercise the _magisterium_ over it, to direct and govern it according to the law of God; not to the body to assume the mastery over the soul, and to bring the law of the mind into captivity to law in the members. So is the church, as representing the spiritual order, and charged with the care of souls, the nobler and superior part of society, and to her belongs the _magisterium_ of entire human society; and it is for her in the moral order to direct and control civil society, by judicially declaring, and applying to its action, the law of God, of which she is, as we have just said, the guardian and judge, and to which it is bound by the Supreme Law-Giver to subordinate its entire official conduct.
