Hi.
Without wanting to give any 'respect' to this fallen angel Lucifer, I will say this:-
1. Scripture indicates he was an angel of beauty:-
Ezekiel 28:13-25 "You were in Eden, the garden of God; Every precious stone was your covering: The sardius, topaz, and diamond, Beryl, onyx, and jasper, Sapphire, turquoise, and emerald with gold. The workmanship of your timbrels and pipes Was prepared for you on the day you were created.
You were the anointed cherub who covers; I established you; You were on the holy mountain of God; You walked back and forth in the midst of fiery stones.
You were perfect in your ways from the day you were created, til iniquity was found in you."(emphasis added)
Let's be clear that satan is a fallen angel, in comparison to the Lord Jesus Christ who is the very Word of God made flesh, not an angel and not the 'brother' of a fallen angel.
2. This fallen angel Lucifer, now known as satan/the devil (the accuser/adversary) was cast out from God's presence, whereas the Lord Jesus is at the right hand of God the Father:
Revelation 12:7-9 "and war broke out in heaven: Michael and his angels fought with the dragon; and the dragon and his angels fought,
but they did not prevail, nor was a place found for them in heaven any longer.
So the great dragon was cast out, that serpent of old, called the Devil and Satan, who deceives the whole world; he was cast to the earth, and his angels were cast out with him."
See Hebrews 1, please try to look objectively, without any LDS commentaries/interpretations, to see the DIFFERENCE in NATURE/ESSENCE between Jesus and angels.
3. The Lord Jesus gives His followers authority over the power of the fallen angel satan:-
Luke 10:17-19 "Then the seventy returned with joy, saying, "Lord, even the demons are subject to us in Your name; and He said to them, "I saw Satan fall like lightning from heaven.
Behold, I give you the authority to trample on serpents and scorpions, and over all the power of the enemy, and nothing shall by any means hurt you."
I will leave it there for now...
I appreciate that we don't want to give light to satan. We do not either.
But, it is imparative that we know who he was at one time in order to have a discussion and full knowledge of how he fits into the scheme of our Heavenly Father.
From the scriptures you have quoted, we know that at one time he was a dazzling, powerful, next to God and Jesus spirit. Whether you call him a cherub, an angel, a spirit, lucifer, it doesn't matter. He was powerful and had a place next to God himself and was once an impressive righteous, perfect person.
We know this because even when he turned against God and Jesus, he was still able to persuade 1/3 of the stars in heaven (other angels) to follow him, and they were so committed to him that he was able to cause a war in heaven. Michael, the archangel had on his side 2/3 of the stars of heaven (other angels) and was able to defeat lucifer and his angels only by the blood of the Lamb (who is Jesus Christ himself).
Lucifer and his angels were forced out of heaven and were thrown down to the earth, to tempt and bother man. lucifer's name was changed to satan, and he was present in Eden to tempt our first parents and helped create the fall of man. So from the beginning, he was doing his best to thwart the plans of God and Jesus.
In lucifer's best moments though, many Christian commentators believe that lucifer was second only to Jesus next to God the Father.
Isaiah says that lucifer was a 'son of the morning', which means that he was one of the first to be created by God the Father.
Now that we know about lucifer/satan, lets turn our attention the Jesus.
We know that Jesus was the firstborn of the spirit children of God.
See Colossians 1:15
15 Who is the image of the invisible God, the firstborn of every creature.
(So we see from this scripture that Jesus was the firstborn of all the creatures of God)
Also see Revelations 3:14
14 And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God.
(Again, we can see that Jesus was the beginning or first of the creations of God)
We know there were many spirit sons of God in heaven from these scriptures:
Job 38:7
When the morning stars sang together, and all the
sons of God shouted for joy?
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.
Job 2:1
Again there was a day when the
sons of God came to present themselves before the Lord, and Satan came also among them to present himself before the Lord.
(So the idea that God had 1 son is not correct. But what is correct is that of all the spirit children of God or sons of God, (angels - of which Jesus was one of them) only one of them was the only-begotten son of God, and that was Jesus. Jesus has the distinction of being the firstborn of the spirit angels/sons of God of God, and he also has the distinction to be the
only-begotten son of God in the flesh.
So when the scriptures say in:
Hebrews 1:4
4 Being made so much better than the angels, as he hath by inheritance obtained a more excellent name than they.
(Jesus was made (notice made) better than the angels because he inherited his Fathers genes and his Fathers name, with was more a more excellent name than for instance, my father's genes and name.
Notice also in Hebrews 2:9
9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
(We notice this scripture because it says Jesus was made (notice made) a little lower than the angels.....)
So in these 2 Hebrews scriptures we have Jesus made far better than angels, and Jesus made a little lower than the angels. I hope that is not too confusing.
In either scripture though the word 'made' is used. So the idea that Jesus was the firstborn (made) spirit son of God, should not be difficult to understand, and it does not derail his divinity, because he has existed forever and ever, just like the Father.
Was Jesus an angel? Many Christian commentators say yes. Many websites say yes, Jesus was an angel, because he was a messenger for the most High God the Father. He was the chief angel. Many scriptures attest to this, In fact being the perfect son and one who hated iniquity and loved righteousness, he became the voice for the Father, and gained the title, the Word of God.
Could Jesus and lucifer be brothers. Of course they could. Jesus was the firstborn of the sons of God. lucifer was a son of the morning, so he was born shortly after, maybe even the second son of God.
Both Jesus and lucifer had to be made/created by the same God, God the Father.
Both Jesus and lucifer are referred to as the morning star.
Isaiah refers to lucifer as the morning star in Isaiah 14:12(ESV) and Jesus is referred to the morning star by himself in Revelation 22:16 (ESV). Therefore many Chistian commentators have suggested that they were both superior individuals at one time.
Lucifer finally chose to go against God, and we know what happened to him. Jesus was always loyal to God. Because of his loyalty and his sinlessness, God the Father brought Jesus to sit by His side. God did not do that for any other of his sons of God (angels), but only Jesus. God the Father called Jesus God and gave him a throne, and a sceptor of righteousness. Jesus's God even annointed his head with the oil of gladness above Jesus's fellow sons of God.
See Hebrews 1:8-9
8 But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom.
9 Thou hast loved righteousness, and hated iniquity; therefore God, even thy God, hath anointed thee with the oil of gladness
above thy fellows.
(who are Jesus's fellows?)
There is a lot of study that goes into this subject. It is not easy to pull out all the scriptures that refer to the pre-mortal existence. But they are certainly there. Hope you take the time to read what I have written. Let me know what you think.
