Selection from Arcana Coelestia ~ Emanuel Swedenborg
There are two kinds of things with men that must be in order, namely, the things that belong to heaven, and the things that belong to the world. The things that belong to heaven are called Ecclesiastical; and the things that belong to the world are called Civil.Order cannot be maintained in the world without overseers, who must take note of all things that are done according to order, and that are done contrary to order; and who must reward those who live according to order, and punish those who live contrary to order.
If this be not done, the human race will perish. For there is born in everyone, by inheritance, the desire to rule over others, and to possess the goods of others. From this come enmities, envyings, hatreds, revenges, deceits, fierce ragings, and many other evils; and therefore unless men are kept in bonds by laws, and by rewards suited to their loves, which are honors and gains for those who do good things; and by punishments contrary to their loves, which are the loss of honors, of possessions, and of life for those who do evil things, the human race must perish.
There must therefore be overseers learned in the law, wise, and god-fearing, to keep the assemblages of men in order. Among the overseers also there must be order, lest anyone should from caprice, or from ignorance, permit evils that are contrary to order, and should thus destroy it. This is guarded against when there are higher and lower overseers, among whom there is subordination.
Overseers over the things with man that belong to heaven, or over ecclesiastical things, are called priests, and their office is called the priesthood. But overseers over such things with man as belong to the world, or over civil matters, are called magistrates, and their chief, where such supreme powers exist, is called a king.
As regards priests, they must teach men the way to heaven, and must also lead them. They must teach them according to the doctrine of their church, and they must lead them to live according to it. Priests who teach truths and by means of them lead to the good of life, and thus to the Lord, are good shepherds of the sheep; but those who teach, and do not lead to the good of life, and thus to the Lord, are evil shepherds. The latter are called by the Lord "thieves and robbers," in John 10:7-16.
Priests must not claim for themselves any power over the souls of men, because they do not know in what state are a man's interiors; and still less must they claim for themselves the power of opening and closing heaven, because this power belongs to the Lord alone.
Priests must have dignity and honor on account of the holy things which they engage in; but those of them who are wise give the honor to the Lord, from whom come all holy things; and not to themselves. But those of them who are not wise attribute the honor to themselves. These take it away from the Lord. Those who attribute honor to themselves on account of the holy things which they engage in, set honor and profit above the salvation of souls, which they ought to have regard for. But those who give the honor to the Lord and not to themselves, set the salvation of souls above honor and profit.
No honor of any employment is in the person; but it is adjoined to him according to the dignity of the thing which he administers, and that which is adjoined is separate from the person, and also is separated from him together with the employment. The honor that is in the person is the honor of the wisdom and fear of the Lord [that he displays].
Priests must teach the people, and lead them to the good of life by means of truths. But they must not compel anyone, because no one can be compelled to believe contrary to what he thinks in his heart to be true. He who believes differently from the priest, and makes no disturbance, must be left in peace; but he who makes a disturbance must be separated; for this also belongs to the order for the sake of which is the priesthood.
As priests are overseers for the administration of the things that belong to the Divine law and to worship, so are kings and magistrates for the administration of the things that belong to the civil law, and to judgment.
As the king alone cannot administer all things, therefore there are overseers under him, to each of whom has been given the official duty of administering what the king cannot attend to. Taken together these overseers constitute the royalty, but the king himself is the chief.
The royalty itself is not in the person, but is adjoined to the person. The king who believes that the royalty is in his own person, and the overseer who believes that the dignity of the overseership is in his own person, is not wise.
The royalty consists in administering according to the laws of the kingdom, and in judging from justice according to these laws. The king who regards the laws as above him, consequently himself as below the laws, is wise; but he who regards himself as above the laws, consequently the laws as beneath him, is not wise.
The king who regards the laws as above himself, and thus himself as beneath the laws, makes the royalty to consist in the law, and the law rules over him; for he knows that the law is justice, and all justice that is justice is Divine. But he who regards the laws as beneath him, and thus himself as above them, makes the royalty to consist in himself, and either believes himself to be the law, or the law which is justice to be from himself; consequently he arrogates to himself that which is Divine, and under which he must be.
The law which is justice must be brought forward by persons in the realm learned in the law, who are wise and god-fearing; in accordance with which the king and his subjects must then live. The king who lives in accordance with the law which is justice, and therein sets an example to his subjects, is truly a king.
A king who has absolute power, and who believes that his subjects are such slaves that he has a right to their lives and properties, and who exercises this power, is not a king, but a tyrant.
The king must be obeyed in accordance with the laws of the realm, nor must he be injured in any way by word or deed, for upon this depends the public safety.
