Angels are spirit beings. It is irrrelevant as to whether they "sing" as understood by Man.
THE ANGELS
The existence of angels - a truth of faith
328 The existence of the spiritual, non-corporeal beings that Sacred Scripture usually calls "angels"
is a truth of faith. The witness of Scripture is as clear as the unanimity of Tradition.
Who are they?
329 St. Augustine says: "'Angel' is the name of their office, not of their nature.
If you seek the name of their nature, it is 'spirit';
if you seek the name of their office, it is 'angel':
from what they are, 'spirit',
from what they do, 'angel.'"
188 With their whole beings the angels are servants and messengers of God.
Because they "always behold the face of my Father who is in heaven"
they are the "mighty ones who do his word, hearkening to the voice of his word".189
330 As purely spiritual creatures angels have intelligence and will:
they are personal and immortal creatures, surpassing in perfection all visible creatures,
as the splendor of their glory bears witness.190
Christ "with all his angels"
331 Christ is the center of the angelic world. They are his angels:
"When the Son of man comes in his glory, and all the angels with him. . "191
They belong to him because they were created through and for him:
"for in him all things were created in heaven and on earth, visible and invisible,
whether thrones or dominions or principalities or authorities - all things were created through him and for him."192
They belong to him still more because he has made them messengers of his saving plan:
"Are they not all ministering spirits sent forth to serve, for the sake of those who are to obtain salvation?"193
332 Angels have been present since before creation of Mankind and throughout the history of salvation,
announcing this salvation from afar or near and serving the accomplishment of the divine plan:
they closed the earthly paradise;
protected Lot;
saved Hagar and her child;
stayed Abraham's hand;
communicated the law by their ministry;
led the People of God;
announced births and callings;
and assisted the prophets,
just to cite a few examples.194
Finally, the angel Gabriel announced the birth of the Precursor and that of Jesus himself.195
333 From the Incarnation to the Ascension, the life of the Word incarnate is surrounded
by the adoration and service of angels.
When God "brings the firstborn into the world, he says: 'Let all God's angels worship him.'"196
Their "song of praise" at the birth of Christ has not ceased resounding in the Church's praise: "Glory to God in the highest!"197
They protect Jesus in his infancy,
serve him in the desert,
strengthen him in his agony in the garden,
when he could have been saved by them from the hands of his enemies as Israel had been.198
Again, it is the angels who "evangelize" by proclaiming the Good News of Christ's Incarnation and Resurrection.199
They will be present at Christ's return, which they will announce, to serve at his judgement.200 (Catechism of Cathoolic Church)
I believe in angels .
Angels have protected me and mine .
I was on my way home one night and I suddenly stopped at a corner that I usually don't stop at .
I'm sure an angel nudged me . If I hadn't stopped I would have hit a woman dressed in dark clothing dead on .
ANGELS: They are in ~34 books, and the word "angel" appears ~275 times.
Jesus on Angels:
(to his disciples) The Parable of the Lost Sheep..."children's angels?"
Matthew 18 (NIV)
10 "See that you do not look down on one of these little ones (childen).
For I tell you that their angels in heaven always see the face of my Father in heaven...
11 The Son of Man came to save what was lost....
he is happier about that one sheep than about the ninety-nine that did not wander off.
14 In the same way your Father in heaven is not willing that any of these little ones should be lost.
(to his disciples) Arrest in the garden of Gethsemane
Matthew 26 (NIV)
52 "Put your sword back in its place," Jesus said to him,
"for all who draw the sword will die by the sword.
53 Do you think I cannot call on my Father,
and he will at once put at my disposal more than twelve legions of angels?
54 But how then would the Scriptures be fulfilled that say it must happen in this way?"
Angels were CREATED before the world in a state of holiness.
Colossians 1 (NIV) The Supremacy of Jesus the Christ
13 For he has rescued us from the dominion of darkness
and brought us into the kingdom of the Son he loves,
14 in whom we have redemption, the forgiveness of sins.
15 He is the image of the invisible God, the firstborn over all creation.
16 For by him all things were created:
things in heaven and on earth,
visible and invisible,
whether thrones or powers or rulers or authorities;
all things were created by him and for him.
17 He is before all things, and in him all things hold together.
18 And he is the head of the body, the church;
he is the beginning and the firstborn from among the dead,
so that in everything he might have the supremacy.
19 For God was pleased to have all his fullness dwell in him,
20 and through him to reconcile to himself all things,
whether things on earth or things in heaven,
by making peace through his blood, shed on the cross.
Angels have intellect, emotions, and free will.
1 Peter 1:12 (NIV)
12 It was revealed to them that they were not serving themselves but you,
when they spoke of the things that have now been told you
by those who have preached the gospel to you by the Holy Spirit sent from heaven.
Even angels long to look into these things.
Luke 2 The Shepherds and the Angels
8 And there were shepherds living out in the fields nearby,
keeping watch over their flocks at night.
9 An angel of the Lord appeared to them,
and the glory of the Lord shone around them,
and they were terrified.
10 But the angel said to them,
"Do not be afraid. I bring you good news of great joy that will be for all the people.
11 Today in the town of David a Savior has been born to you; he is Christ the Lord.
12 This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger."
13 Suddenly a great company of the heavenly host appeared with the angel, praising God and saying,
14 "Glory to God in the highest, and on earth peace to men on whom his favor rests."
15 When the angels had left them and gone into heaven, the shepherds said to one another,
"Let's go to Bethlehem and see this thing that has happened, which the Lord has told us about."
Jude 1
6 And the angels who did not keep their positions of authority but abandoned their own home
—these he has kept in darkness, bound with everlasting chains for judgment on the great Day.
Angels are SPIRIT beings who live forever, not human, do not reproduce, and have great power.
One ARCHangel is named "Michael". Another named "Gabriel"? Seraphim! Cherabim!
Do they have wings? Most have appeared as a man dressed in white...glowing?
"Guardian Angels":
Hebrews 1 The Jesus the God-Man, the Son, the Messaih is Superior to Angels
14 Are not all angels ministering spirits sent to serve those who will inherit salvation?
Angels have been and may be MESSENGERS, who PREDICT, ANNOUNCE, PROTECT, DEFEND, AID, CARE for,OBSERVE, ENCOURAGE those who believe.
