# Summa Theologica, First Half

*Thomas Aquinas, tr. Fathers of the English Dominican Province*

God and creation, human action, law and grace, then faith, hope, charity and justice.

## 1176. II–II · Q. 104, Art. 6: Whether Christians are bound to obey the secular powers?

[¶0] Whether Christians are bound to obey the secular powers?

[¶1] Objection 1: It seems that Christians are not bound to obey the secular power. For a gloss on Mat. 17:25, "Then the children are free," says: "If in every kingdom the children of the king who holds sway over that kingdom are free, then the children of that King, under Whose sway are all kingdoms, should be free in every kingdom." Now Christians, by their faith in Christ, are made children of God, according to Jn. 1:12: "He gave them power to be made the sons of God, to them that believe in His name." Therefore they are not bound to obey the secular power.

[¶2] Objection 2: Further, it is written (Rom. 7:4): "You . . . are become dead to the law by the body of Christ," and the law mentioned here is the divine law of the Old Testament. Now human law whereby men are subject to the secular power is of less account than the divine law of the Old Testament. Much more, therefore, since they have become members of Christ's body, are men freed from the law of subjection, whereby they were under the power of secular princes.

[¶3] Objection 3: Further, men are not bound to obey robbers, who oppress them with violence. Now, Augustine says (De Civ. Dei iv): "Without justice, what else is a kingdom but a huge robbery?" Since therefore the authority of secular princes is frequently exercised with injustice, or owes its origin to some unjust usurpation, it seems that Christians ought not to obey secular princes.

[¶4] On the contrary, It is written (Titus 3:1): "Admonish them to be subject to princes and powers," and (1 Pet. 2:13,14): "Be ye subject . . . to every human creature for God's sake: whether it be to the king as excelling, or to governors as sent by him."

[¶5] I answer that, Faith in Christ is the origin and cause of justice, according to Rom. 3:22, "The justice of God by faith of Jesus Christ:" wherefore faith in Christ does not void the order of justice, but strengthens it." Now the order of justice requires that subjects obey their superiors, else the stability of human affairs would cease. Hence faith in Christ does not excuse the faithful from the obligation of obeying secular princes.

[¶6] Reply to Objection 1: As stated above (A 5), subjection whereby one man is bound to another regards the body; not the soul, which retains its liberty. Now, in this state of life we are freed by the grace of Christ from defects of the soul, but not from defects of the body, as the Apostle declares by saying of himself (Rom. 7:23) that in his mind he served the law of God, but in his flesh the law of sin. Wherefore those that are made children of God by grace are free from the spiritual bondage of sin, but not from the bodily bondage, whereby they are held bound to earthly masters, as a gloss observes on 1 Tim. 6:1, "Whosoever are servants under the yoke," etc.

[¶7] Reply to Objection 2: The Old Law was a figure of the New Testament, and therefore it had to cease on the advent of truth. And the comparison with human law does not stand because thereby one man is subject to another. Yet man is bound by divine law to obey his fellow-man.

[¶8] Reply to Objection 3: Man is bound to obey secular princes in so far as this is required by order of justice. Wherefore if the prince's authority is not just but usurped, or if he commands what is unjust, his subjects are not bound to obey him, except perhaps accidentally, in order to avoid scandal or danger.

### II–II · Question 105: Of Disobedience (two Articles)

[¶10] OF DISOBEDIENCE (TWO ARTICLES)

[¶11] We must now consider disobedience, under which head there are two points of inquiry:

[¶12] (1) Whether it is a mortal sin?

[¶13] (2) Whether it is the most grievous of sins?

### II–II · Q. 105, Art. 1: Whether disobedience is a mortal sin?

[¶15] Whether disobedience is a mortal sin?

[¶16] Objection 1: It seems that disobedience is not a mortal sin. For every sin is a disobedience, as appears from Ambrose's definition given above (Q 104, A 2, OBJ). Therefore if disobedience were a mortal sin, every sin would be mortal.

[¶17] Objection 2: Further, Gregory says (Moral. xxxi) that disobedience is born of vainglory. But vainglory is not a mortal sin. Neither therefore is disobedience.

[¶18] Objection 3: Further, a person is said to be disobedient when he does not fulfil a superior's command. But superiors often issue so many commands that it is seldom, if ever, possible to fulfil them. Therefore if disobedience were a mortal sin, it would follow that man cannot avoid mortal sin, which is absurd. Wherefore disobedience is not a mortal sin.

[¶19] On the contrary, The sin of disobedience to parents is reckoned (Rom. 1:30; 2 Tim. 3:2) among other mortal sins.

[¶20] I answer that, As stated above (Q 24, A 12; FS, Q 72, A 5; FS, Q 88, A 1), a mortal sin is one that is contrary to charity which is the cause of spiritual life. Now by charity we love God and our neighbor. The charity of God requires that we obey His commandments, as stated above (Q 24, A 12). Therefore to be disobedient to the commandments of God is a mortal sin, because it is contrary to the love of God.

[¶21] Again, the commandments of God contain the precept of obedience to superiors. Wherefore also disobedience to the commands of a superior is a mortal sin, as being contrary to the love of God, according to Rom. 13:2, "He that resisteth the power, resisteth the ordinance of God." It is also contrary to the love of our neighbor, as it withdraws from the superior who is our neighbor the obedience that is his due.

[¶22] Reply to Objection 1: The definition given by Ambrose refers to mortal sin, which has the character of perfect sin. Venial sin is not disobedience, because it is not contrary to a precept, but beside it. Nor again is every mortal sin disobedience, properly and essentially, but only when one contemns a precept, since moral acts take their species from the end. And when a thing is done contrary to a precept, not in contempt of the precept, but with some other purpose, it is not a sin of disobedience except materially, and belongs formally to another species of sin.

[¶23] Reply to Objection 2: Vainglory desires display of excellence. And since it seems to point to a certain excellence that one be not subject to another's command, it follows that disobedience arises from vainglory. But there is nothing to hinder mortal sin from arising out of venial sin, since venial sin is a disposition to mortal.

[¶24] Reply to Objection 3: No one is bound to do the impossible: wherefore if a superior makes a heap of precepts and lays them upon his subjects, so that they are unable to fulfil them, they are excused from sin. Wherefore superiors should refrain from making a multitude of precepts.
