On the contrary the angels were created for the service of God and the service of man. They are his angelos which means messengers. They do not partake of the Divine Nature as man does. From the Catechism of the Catholic Church:
[quote=CCC 460]The Word became flesh to make us “partakers of the divine nature”:78 "For this is why the Word became man, and the Son of God became the Son of man: so that man, by entering into communion with the Word and thus receiving divine sonship, might become a son of God."79 "For the Son of God became man so that we might become God."80 "The only-begotten Son of God, wanting to make us sharers in his divinity, assumed our nature, so that he, made man, might make men gods."81
The references are:
78: 2 Peter 1:4
79: St. Irenaeus, Adv. haeres. 3, 19, 1: PG 7/1, 939.
80: St. Athanasius, De inc. 54, 3: PG 25, 192B.
81:St. Thomas Aquinas, Opusc. 57, 1-4.
In effect we are Divinized. This is not a dignity that the angels can receive as they were not created for that purpose. So, the dignity of a human person in the state of Sanctifying Grace is infinitely greater than the dignity of any angel.
Many of the Early Church Fathers speak about this Divinization and at times I think that we forget our place in the Divine Plan.
