According to Catholicism, if there is human dignity is there also an angelic dignity? If there is human dignity is there also an angelic dignity?

What does Catholcism say about this?
If there is human dignity is there also an angelic dignity?

First of all, what is a Catholic definition of dignity


  The excellence that deserves recognition and praise in a person or thing. Highest in dignity is God, whose superiority over all creation is the basis for adoration. (Etym. Latin dignitas, dignity, worthiness, worth.)


St. Thomas Aquinas responds in the affirmative: Yes the angels possess an angelic dignity.


  From what has been said above (I:108:6), it may be shown that some angels are sent in ministry by God. For, as we have already stated (I:43:1, in treating of the mission of the Divine Persons, he is said to be sent who in any way proceeds from another so as to begin to be where he was not, or to be in another way, where he already was. Thus the Son, or the Holy Ghost is said to be sent as proceeding from the Father by origin; and begins to be in a new way, by grace or by the nature assumed, where He was before by the presence of His Godhead; for it belongs to God to be present everywhere, because, since He is the universal agent, His power reaches to all being, and hence He exists in all things (I:8:1). An angel's power, however, as a particular agent, does not reach to the whole universe, but reaches to one thing in such a way as not to reach another; and so he is "here" in such a manner as not to be "there." But it is clear from what was above stated (I:110:1), that the corporeal creature is governed by the angels. Hence, whenever an angel has to perform any work concerning a corporeal creature, the angel applies himself anew to that body by his power; and in that way begins to be there afresh. Now all this takes place by Divine command. Hence it follows that an angel is sent by God.
  
  The empyrean heaven belongs to the angelic dignity by way of congruity; forasmuch as it is congruous that the higher body should be attributed to that nature which occupies a rank above bodies. Yet an angel does not derive his dignity from the empyrean heaven; so when he is not actually in the empyrean heaven, nothing of his dignity is lost, as neither does a king lessen his dignity when not actually sitting on his regal throne, which suits his dignity.


According to the Catechism of the Catholic Church, man should respect the angels as being created spiritual creatures that aid us here on earth.


  In Brief 
  
  350 Angels are spiritual creatures who glorify God without ceasing and who serve his saving plans for other creatures: "The angels work together for the benefit of us all" (St. Thomas Aquinas, STh I, 114, 3, ad 3).
  
  351 The angels surround Christ their Lord. They serve him especially in the accomplishment of his saving mission to men.
  
  352 The Church venerates the angels who help her on her earthly pilgrimage and protect every human being.
  
  353 God willed the diversity of his creatures and their own particular goodness, their interdependence and their order. He destined all material creatures for the good of the human race. Man, and through him all creation, is destined for the glory of God.
  
  354 Respect for laws inscribed in creation and the relations which derive from the nature of things is a principle of wisdom and a foundation for morality.


An interesting note is that St. Gregory of Nazianzen teaches us that the sacerdotal dignity of ordained Catholic priests surpasses the dignity of the angels, who have a high esteem and reverence for the priesthood.
