Education, so far as it embraces instruction in the several arts and sciences which subserve man's natural life, belongs to the domain of the State; so far as it embraces the formation of the spiritual character in man, which includes instruction in religion, and that not only as it concerns dogma, but also philosophy and science, belongs to the domain of the Church. If the State exercises its natural right over education with regard to the former, without allowing the supernatural right of the Church over the latter, which in itself would be no more than a separate action in its own sphere, it would constitute, at the same time, a complete infringement of the Church's rights in her spiritual power of teaching and jurisdiction. This is enough to show that the separate action of the two Powers in their respective spheres leads to the disjunction of man's natural life from his supernatural end. This was not the intention of God in creating the two Powers, and placing man's life under their joint government. 5. Another relation between the two Powers which may be conceived, is that of hostility upon the part of the State to the Church. This cannot be reciprocal. The Church can indeed and must resist, with her own weapons, unlawful aggression against the exercise of her rights in administering the "things of God," but she cannot war against the State as such, because it is in her sight "the minister of God." The hostility of the State which invades the Church's exercise of her Priesthood, Teaching, and Jurisdiction constitutes persecution. There are many degrees of this. A heathen State may aim at the complete destruction of the Christian Church within its borders, as at times the Roman emperors did. A Christian State may also vex and hamper with every form of impediment the exercise of the Church's powers. A State which has been Christian, becoming heretical or apostate, may assault the Church with a hatred, combined with deceit, which shall surpass the malignity of the Roman State of old or the heathen State at any time. In the course of centuries every degree of persecution has been exercised by the State, heathen, Christian, heretical, or apostate, against the Church, by the permission of the divine Providence; but no one will pretend to say that such a relation as hostility on the part of the State, and of suffering on the part of the Church, is the normal relation intended by God in the establishment of the two Powers. On the contrary, the States which persecute the Church, while they fulfil the divine purpose for its trial and purification, incur punishment in many ways for their crime against God in assaulting His kingdom, and, if they persevere, have been and are to be rooted up and destroyed.
