What we have just said amounts to this, that the whole life of man, whether single or in society, while he lives upon earth, is subject to the life which he hopes for in heaven as its supreme purpose and end; and that being so subject, as there is a society to aid him in attaining the goods of his natural life, so much more is there a society to aid him in attaining that supernatural good to which the natural goods are subordinate. We have next to compare the regimens of these two societies with each other in regard to their completeness. The analogy between the Two Powers is full of instruction; but it is to be remembered that as, since the coming of Christ, the Spiritual Power is one in all countries and in all times, whereas the Temporal Power is one only in each country and at each time, the comparison of the two can only take those points which belong to the Temporal Power alike in all countries and times; and this will be found sufficient for our purpose. We have just seen the conception of spiritual jurisdiction as wielding the priesthood and the teaching: it corresponds in this respect to secular sovereignty, under which is ranged on the one hand authority in every degree, as held by all officials in administration, by all councillors in legislating, by all judges in their several tribunals, by all officers in the public force. Whoever in the public service holds a portion of the public authority may be ranged under the general head of magistrate, and stands herein to the sovereign power in the same relation as the priest to the bearer of supreme spiritual jurisdiction. On the other hand, whoever is engaged in the whole circle of human arts and sciences, which comprehends the vast domain of human knowledge as acquired by learning, answers to the spiritual teacher. This triple division runs through every state, at every time, whatever may be its relative advancement in the scale of government. And the comparison as to both Powers is exhaustive with regard to their range, since in both, man, individual or collective, is a being who acts because he first knows and then wills. Sovereignty, presiding in the various kinds of magistracy over all who command, and over all in the various arts and sciences who teach, because they have first learned, covers that triple domain in the one case, and in the other spiritual royalty, which acts through the priest and the teacher. But the society is knit together in a much stricter bond, by a far more perfect interaction of forces, in the spiritual than in the temporal order; and this arises from the fact that all spiritual power in its triple range actually descends from the spiritual head through every degree, which is far from being the fact in temporal sovereignty. That is the pre-eminence of Christ in His spiritual kingdom; and it is the perfection of the Divine Legislator that He exercises His royalty by the indivisible action of His Jurisdiction,
