On the contrary, The Mother of God is a mere creature. Therefore the worship of latria is not due to her.
I answer that, Since latria is due to God alone, it is not due to a creature so far as we venerate a creature for its own sake. For though insensible creatures are not capable of being venerated for their own sake, yet the rational creature is capable of being venerated for its own sake. Consequently the worship of latria is not due to any mere rational creature for its own sake. Since, therefore, the Blessed Virgin is a mere rational creature, the worship of latria is not due to her, but only that of dulia: but in a higher degree than to other creatures, inasmuch as she is the Mother of God. For this reason we say that not any kind of dulia is due to her, but hyperdulia.
Reply Obj. 1: The honor due to the king's mother is not equal to the honor which is due to the king: but is somewhat like it, by reason of a certain excellence on her part. This is what is meant by the authorities quoted.
Reply Obj. 2: The honor given to the Mother reflects on her Son, because the Mother is to be honored for her Son's sake. But not in the same way as honor given to an image reflects on its exemplar: because the image itself, considered as a thing, is not to be venerated in any way at all.
Reply Obj. 3: The cross, considered in itself, is not an object of veneration, as stated above (AA. 4, 5). But the Blessed Virgin is in herself an object of veneration. Hence there is no comparison. _______________________
SIXTH ARTICLE [III, Q. 25, Art. 6]
Whether Any Kind of Worship Is Due to the Relics of the Saints?
Objection 1: It would seem that the relics of the saints are not to be worshiped at all. For we should avoid doing what may be the occasion of error. But to worship the relics of the dead seems to savor of the error of the Gentiles, who gave honor to dead men. Therefore the relics of the saints are not to be honored.
Obj. 2: Further, it seems absurd to venerate what is insensible. But the relics of the saints are insensible. Therefore it is absurd to venerate them.
Obj. 3: Further, a dead body is not of the same species as a living body: consequently it does not seem to be identical with it. Therefore, after a saint's death, it seems that his body should not be worshiped.
