That the angels are created and that we are not pre-existent as spirit children, means we are not "brothers" with angels.
You teach there are three kinds of beings, God who is one of kind, angels with wings etc and then mankind, mortal and evil.
We teach there is only one kind of being and they all make up on eternal family of heaven and earth, Eph 3:14-15.
We’ll start with;
Rev 12
“And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels,
……And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ:
for the accuser of our brethren is cast down, which accused them before our God day and night.
And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.”
What is this talking about? Who are the brothers
Two examples;
Zech
1 And he shewed me Joshua the high priest standing before the angel of the Lord, and Satan standing at his right hand to resist him.
2 And the Lord said unto Satan, The Lord rebuke thee, O Satan; even the Lord that hath chosen Jerusalem rebuke thee: is not this a brand plucked out of the fire?
Job 1
6 ¶Now there was a day when the sons of God came to present themselves before the Lord, and Satan came also among them.
7 And the Lord said unto Satan, Whence comest thou? Then Satan answered the Lord, and said, From going to and fro in the earth, and from walking up and down in it.
8 And the Lord said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil?
9 Then Satan answered the Lord, and said, Doth Job fear God for nought?
Satan’s original calling was to be the accuser, it wasn’t an evil calling. In the pre-earth life he was to give opposition, to ask is this person worthy of the calling?(see Jer 1) After time he became angry with the situation and tried to replace Jesus.
Obviously we are the angels brothers.
Here is another passage
Rev 1
8 And I John saw these things, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel which shewed me these things.
9 Then saith he unto me, See thou do it not:
for I am thy fellowservant, and of thy brethren the prophets, and of them which keep the sayings of this book: worship God.
And then Job 38
4 Where wast thou when I laid the foundations of the earth? declare, if thou hast understanding.
7 When the morning stars sang together, and all the sons of God shouted for joy?
Morning ‘stars’ as in plural. One of Jesus titles is “the morning star” Rev 22:16. And Lucifer is also known as the morning star or star of dawn. See Isa 14:12 in the Hebrew. These two stars, brothers, sang together at the foundation of the world along with the other Sons of God.
Luke 3: 38 Which was the son of Enos, which was the son of Seth,
which was the son of Adam, which was the son of God.
Adam was there along with the rest of us.
“ Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.” John 20
