No it isn't.
In the Bible, angels has to do with ... angels. Not things men do that may be "eloquent".
No one knows if there is a heavenly language, or the language that is pre-Tower of Babel, and I am of the opinion, that GOD put into ADAM the pre-TOWER of Babel language spoken in heaven too, which seems MORE LIKELY than the mysterious heavenly Language THEORY.
Yes it is, the VOICE of Authority, with an eloquence beyond normal speech, was how Men perceived them, but it obviously was an Earthly language.
Matthew 1:20-25 (ASV)
20 But when he thought on these things, behold, an angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Spirit.
21 And she shall bring forth a son; and thou shalt call his name JESUS; for it is he that shall save his people from their sins.
22 Now all this is come to pass, that it might be fulfilled which was spoken by the Lord through the prophet, saying,
23 Behold, the virgin shall be with child, and shall bring forth a son, And they shall call his name Immanuel; which is, being interpreted, God with us.
24 And
Joseph arose from his sleep, and did as the angel of the Lord commanded him, and took unto him his wife;
25 and knew her not till she had brought forth a son: and he called his name JESUS.
The Angel Commanded that Voice of Authority.
AND, I think MARY would argue with you:
Luke 1:26-35 (ASV)
26 Now in the sixth month
the angel Gabriel was sent from God unto a city of Galilee, named Nazareth,
27 to a virgin betrothed to a man whose name was Joseph, of the house of David; and the virgin's name was Mary.
28 And he came in unto her, and said, Hail, thou that art highly favored, the Lord
is with thee.
29
But she was greatly troubled at the saying, and cast in her mind what manner of salutation this might be.
30
And the angel said unto her, Fear not, Mary: for thou hast found favor with God.
31 And behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS.
32 He shall be great, and shall be called the Son of the Most High: and the Lord God shall give unto him the throne of his father David:
33 and he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
34 And Mary said unto the angel, How shall this be, seeing I know not a man?
35 And the angel answered and said unto her, The Holy Spirit shall come upon thee, and the power of the Most High shall overshadow thee: wherefore also the holy thing which is begotten shall be called the Son of God.
Okay, even MARY noticed the difference in his Voice.
Genesis 21:17 (ASV)
17 And God heard the voice of the lad. And the angel of God called to Hagar out of heaven, and said unto her, What aileth thee, Hagar?
Fear not. For God hath heard the voice of the lad where he is.
Merriam-Webster, defines
Eloquence definition is - discourse marked by force and persuasiveness.
What do you call that?
Now here is possibly the Pre-Incarnate Christ:
Genesis 22:11-12 (ASV)
11 And the angel of Jehovah called unto him out of heaven, and said, Abraham, Abraham. And he said,
Here I am.
12 And he said, Lay not thy hand upon the lad, neither do thou anything unto him. For now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son, from me.
Now that is the ULTIMATE UNDERSTATEMENT, because I have heard the voice of the LORD at least Twice in my life. I guarantee you that Abraham was shaking in his bootstraps. Both times I guarantee you that I WAS.
One time when my wife and I were just a few short years into our marriage. My wife got addicted to pain pills, and I had all kinds of people praying for her. Even her Mother came over to stay with her for awhile. One mourning as she got up, she SAW her mother Praying for Her. My wife broke down in mournful TEARS, and fell on her knees to begging the Lord to take the addiction away. YES HE DID. From a lethal dose for most people (that indicates that she was addicted for quite awhile because she built up a tolerance),
TO ZERO, WITH NO WITHDRAWAL SYMPTOMS. When we went to her Dr. to explain why she did not need the Rehab Center now. Her Doctor just snapped back "If you believe that you are either a FOOL or a LIAR." And I knew then that her Doctor was a non-christian. So he insisted she would have to go thru Rehab. A few days into that NON-CHRISTIAN Rehab, I got called in for a Group Therapy Session. There were two Counselors and the rest of the GROUP. And they were itching to start with my wife and I, as she told me they were making fun of her faith. AND YES, THEY DID. They were making fun that we thought we could Trust the LORD, instead of them. ALL OF A SUDDEN A BOOMING VOICE CAME INTO TO MY HEAD, AND SAID JUST ONE WORD,
WALK ! ! ! I CAME OUT OF THAT CHAIR AS IF IT HAD BEEN ELECTRIFIED, I MEAN THEIR WAS NO WAY I COULD NOT MAKE MY MUSCLES NOT OBEY THAT VOICE. I looked over to my wife and said, "ARE YOU READY." AND SHE SAID "YES." When we got out to my Jeep, there was a flat tire, so I busied myself to changing the tire, and I had not asked her what had just happened. Just as I was about to tighten the last lug nut, she got out of the care and came back to the left rear tire where I was, so I asked, "Did you hear anything in that room?" She said, "Just one word, WALK ! ! !" I said, "THAT IS IT, we are out of here!"
About 10 years later, when we were living in Crescent City, California, I was driving by myself back to Nebraska, by myself. I was going to pick up Grand-kids to come out to the coast for a vacation. I spent the first night in a MOTEL in Elko, NV. The next mourning as I was on the on ramp to I-80, I noticed a hitch hiker as, so I stirred to the left giving him enough room and sped up, not intending to pick him up. I was at merging speed 65 m.p.h., when that same BOOMING VOICE SHOUTED,
"PICK HIM UP ! ! !" I MEAN the FASTEST that I stopped from 65 m.p.h., with all four wheels screaming on the pavement. INSTANT MUSCLE REACTION AND EVERYTHING. I was sitting in the car SHAKING, when the hitch hiker ran up to where my car was, opened the door, and asked "Are you stopping to give me a ride?" I said, "Yeah, you get in the car, because GOD JUST TOLD ME TO "PICK YOU UP ! ! !" To make A LONG STORY SHORT, I was blessed by leading him to the LORD that DAY.
So you can see, you will have NO CHANCE that Angels speak in an Non-Eloquent voice, especially when I see JOHN in his Vision or Reality bowing to an angel.
Revelation 19:9-10 (NIV)
9 Then the angel said to me, "Write: 'Blessed are those who are invited to the wedding supper of the Lamb!'" And he added, "These are the true words of God."
10 At this I fell at his feet to worship him. But he said to me, "Do not do it! I am a fellow servant with you and with your brothers who hold to the testimony of Jesus. Worship God! For the testimony of Jesus is the spirit of prophecy."
