Natural order is the field open to man's knowledge. Supernatural order is so in degree to his faith and hope; but knowledge does not penetrate it. In the order of nature man exercises a share of action and power; in supernatural order he has but to submit. It has been said in the spirit of conciliation and peace, "Religion and Philosophy are sisters who should mutually respect and protect each other." The words bear the stamp of the chimæras of human pride. Philosophy springs from man; it is the work of his mind. Religion comes from God; man receives it, and often alters it after reception, but he does not create it. Religion and philosophy are not sisters. They are daughters, the one of "Our Father which is in Heaven," the other of mere human genius. And their condition in this world is no more equal than their origin. Authority is the apanage of religion; liberty is that of philosophy.

I now approach the second of the dominant ideas, more than ever essential to true order, and which I wish to bring prominently forward.

"Christianity," says M. Veuillot, "is authority." It is true; Christianity is authority, but it is not authority only; it is the entire man, all his nature and all his destiny. Now, moral obedience is the nature and destiny of man; that is, obedience in a state of liberty. God created man to obey His laws; he created him free that he might morally obey. Liberty, like authority, is of divine institution; the work of man is revolt and tyranny.

In the social state, authority and liberty need protection, and both have a right to it. There is need of control, both for the governors and the governed, for both are men. Hence political laws and institutions which now sustain, now limit power; that is, which decide on what conditions and by what means authority is to be exercised and liberty secured.

What is the measure of authority necessary for Government, what the extent of liberty possible in human society? What are the means of action, what the pledges to be given alike to authority and religion? Matters depending on circumstances, variable according to the times, the social condition, the manners, races, and different degrees of civilization amongst nations. It belongs to the politician to solve these questions.

When Christianity appeared in the world, appeal was first made to liberty, the moral liberty of man. This was necessary, as it came to abolish ancient creeds which were protected by the established powers. In this struggle, not only did growing Christianity never attack or question the existing authorities, but it formally acknowledged their rights, and while respecting them herself ordered others to respect them also. But at the same time, as regards the relations of men towards God, she appealed to the free consciences of men, and affirmed in principle the same liberty which she practised. "We must obey God rather than man," said St. Peter. "Try the spirits whether they be of God," said St. John. "I speak as to wise men, judge ye what I say," said St. Paul.

At the creation God prescribed obedience to men under penalty of death; in the day of regeneration God set man's liberty in motion to begin the work of salvation.

There is no partiality with God, no void in his designs; when he acts upon man he takes human nature as a whole; our inclinations, our wants, our interests, our various rights are all before his eyes. He at the same time provides for and satisfies all; authority as well as liberty, liberty as well as authority. It is a dangerous mistake to misapprehend this complete and harmonious character of the divine work, and to mutilate it by seeking weapons in it for our human dissensions. Christ came to save mankind, not to give a party triumph. Christianity began by invoking liberty and giving her action. She then overcame, and set forth her authority. She then accommodated herself to the various forms and degrees of authority and liberty which the course of events brought out here and there in the world. Associated with the destinies and deeds of the human race, Christianity has suffered for our mistakes and faults, and has been often altered and compromised by the waywardness of human liberty and authority. But by her origin and essence she is beyond the reach of their struggles, inexhaustible in her virtue to heal contradictory evils, and always ready to afford help on the side where danger threatens or redress is needed.
