Reply to Objection 1: The angel forbade John to pay him, not any kind of honor, but the honor of adoration and latria, which is due to God. Or again, he forbade him to pay the honor of dulia, in order to indicate the dignity of John himself, for which Christ equaled him to the angels "according to the hope of glory of the children of God": wherefore he refused to be honored by him as though he were superior to him.
Reply to Objection 2: A wicked superior is honored for the excellence, not of his virtue but of his dignity, as being God's minister, and because the honor paid to him is paid to the whole community over which he presides. As for the demons, they are wicked beyond recall, and should be looked upon as enemies, rather than treated with honor.
Reply to Objection 3: In every man is to be found something that makes it possible to deem him better than ourselves, according to Phil. 2:3, "In humility, let each esteem others better than themselves," and thus, too, we should all be on the alert to do honor to one another.
Reply to Objection 4: Private individuals are sometimes honored by kings, not that they are above them in the order of dignity but on account of some excellence of their virtue: and in this way Tobias and Mardochaeus were honored by kings.
Whether dulia is a special virtue distinct from latria?
Objection 1. It seems that dulia is not a special virtue distinct from latria. For a gloss on Ps. 7:1, "O Lord my God, in Thee have I put my trust," says: "Lord of all by His power, to Whom dulia is due; God by creation, to Whom we owe latria." Now the virtue directed to God as Lord is not distinct from that which is directed to Him as God. Therefore dulia is not a distinct virtue from latria.
Objection 2: Further, according to the Philosopher (Ethic. viii, 8), "to be loved is like being honored." Now the charity with which we love God is the same as that whereby we love our neighbor. Therefore dulia whereby we honor our neighbor is not a distinct virtue from latria with which we honor God.
Objection 3: Further, the movement whereby one is moved towards an image is the same as the movement whereby one is moved towards the thing represented by the image. Now by dulia we honor a man as being made to the image of God. For it is written of the wicked ( Wis. 2:22 , 23 ) that "they esteemed not the honor of holy souls, for God created man incorruptible, and to the image of His own likeness He made him." Therefore dulia is not a distinct virtue from latria whereby God is honored.
On the contrary, Augustine says (De Civ. Dei x), that "the homage due to man, of which the Apostle spoke when he commanded servants to obey their masters and which in Greek is called dulia, is distinct from latria which denotes the homage that consists in the worship of God."
I answer that, According to what has been stated above (Q[101], A[3]), where there are different aspects of that which is due, there must needs be different virtues to render those dues. Now servitude is due to God and to man under different aspects: even as lordship is competent to God and to man under different aspects. For God has absolute and paramount lordship over the creature wholly and singly, which is entirely subject to His power: whereas man partakes of a certain likeness to the divine lordship, forasmuch as he exercises a particular power over some man or creature. Wherefore dulia, which pays due service to a human lord, is a distinct virtue from latria, which pays due service to the lordship of God. It is, moreover, a species of observance, because by observance we honor all those who excel in dignity, while dulia properly speaking is the reverence of servants for their master, dulia being the Greek for servitude.
Reply to Objection 1: Just as religion is called piety by way of excellence, inasmuch as God is our Father by way of excellence, so again latria is called dulia by way of excellence, inasmuch as God is our Lord by way of excellence. Now the creature does not partake of the power to create by reason of which latria is due to God: and so this gloss drew a distinction, by ascribing latria to God in respect of creation, which is not communicated to a creature, but dulia in respect of lordship, which is communicated to a creature.
Reply to Objection 2: The reason why we love our neighbor is God, since that which we love in our neighbor through charity is God alone. Wherefore the charity with which we love God is the same as that with which we love our neighbor. Yet there are other friendships distinct from charity, in respect of the other reasons for which a man is loved. In like manner, since there is one reason for serving God and another for serving man, and for honoring the one or the other, latria and dulia are not the same virtue.
Reply to Objection 3: Movement towards an image as such is referred to the thing represented by the image: yet not every movement towards an image is referred to the image as such, and consequently sometimes the movement to the image differs specifically from the movement to the thing. Accordingly we must reply that the honor or subjection of dulia regards some dignity of a man absolutely. For though, in respect of that dignity, man is made to the image or likeness of God, yet in showing reverence to a person, one does not always refer this to God actually.
Or we may reply that the movement towards an image is, after a fashion, towards the thing, yet the movement towards the thing need not be towards its image. Wherefore reverence paid to a person as the image of God redounds somewhat to God: and yet this differs from the reverence that is paid to God Himself, for this in no way refers to His image.
Whether dulia has various species?
Objection 1: It seems that dulia has various species. For by dulia we show honor to our neighbor. Now different neighbors are honored under different aspects, for instance king, father and master, as the Philosopher states (Ethic. ix, 2). Since this difference of aspect in the object differentiates the species of virtue, it seems that dulia is divided into specifically different virtues.
Objection 2: Further, the mean differs specifically from the extremes, as pale differs from white and black. Now hyperdulia is apparently a mean between latria and dulia: for it is shown towards creatures having a special affinity to God, for instance to the Blessed Virgin as being the mother of God. Therefore it seems that there are different species of dulia, one being simply dulia, the other hyperdulia.
Objection 3: Further, just as in the rational creature we find the image of God, for which reason it is honored, so too in the irrational creature we find the trace of God. Now the aspect of likeness denoted by an image differs from the aspect conveyed by a trace. Therefore we must distinguish a corresponding difference of dulia: and all the more since honor is shown to certain irrational creatures, as, for instance, to the wood of the Holy Cross.
On the contrary, Dulia is condivided with latria. But latria is not divided into different species. Neither therefore is dulia.
I answer that, Dulia may be taken in two ways. In one way it may be taken in a wide sense as denoting reverence paid to anyone on account of any kind of excellence, and thus it comprises piety and observance, and any similar virtue whereby reverence is shown towards a man. Taken in this sense it will have parts differing specifically from one another. In another way it may be taken in a strict sense as denoting the reverence of a servant for his lord, for dulia signifies servitude, as stated above (A[3]). Taken in this sense it is not divided into different species, but is one of the species of observance, mentioned by Tully (De Invent. Rhet. ii), for the reason that a servant reveres his lord under one aspect, a soldier his commanding officer under another, the disciple his master under another, and so on in similar cases.
Reply to Objection 1: This argument takes dulia in a wide sense.
Reply to Objection 2: Hyperdulia is the highest species of dulia taken in a wide sense, since the greatest reverence is that which is due to a man by reason of his having an affinity to God.
Reply to Objection 3: Man owes neither subjection nor honor to an irrational creature considered in itself, indeed all such creatures are naturally subject to man. As to the Cross of Christ, the honor we pay to it is the same as that which we pay to Christ, just as the king's robe receives the same honor as the king himself, according to Damascene (De Fide Orth. iv).
