Technically it is an old belief that there were seven principal angels (it was already expressed in the book of Tobit) - and as I mentioned, there were already certain people who came up with the idea that Jesus was originally one of those seven angels who got ‘promoted’ to being the Son of God, just as there are people who thought of Jesus as a mere man born through natural generation or that the preexisting heavenly power called Christ descended to the man Jesus on His baptism or that Jesus and Adam are one and the same person.
I know of one sermon written by an anonymous 2nd-3rd century North African ascetic - but ascribed to Cyprian of Carthage - which expresses this view, saying that God created those seven angels from fire and made one of those His son (there is a scribal gloss in the manuscript which makes clear that it is “
against the universal/catholic faith”), and that this ‘promoted’ angel is the “
Lord Sabaoth/Lord of hosts” of Isaiah’s vision!
Some state that one of the possible sources of the “Christ=angel” belief is that Jewish work entitled the
Prayer of Joseph, which explicitly states the belief that an angel could appear both as an angel and a man: some believe that the work may present Jacob as a human incarnation of an angel called Israel, who competed with Uriel over their rank:
Thus Jacob says: “
I, Jacob, who speak to you, and Israel, I am an angel of God, a ruling spirit, and Abraham and Isaac were created before every work of God; and I am Jacob, called Jacob by men, but my name is Israel, called Israel by God, a man seeing God, because I am the first-born of every creature which God caused to live.”
And he adds: “
When I was coming from Mesopotamia of Syria, Uriel, the angel of God, came forth, and said, I have come down to the earth and made my dwelling among men, and I am called Jacob by name. He was angry with me and fought with me and wrestled against me, saying that his name and the name of Him who is before every angel should be before my name. And I told him his name and how great he was among the sons of God;
Are you not Uriel my eighth, and I am Israel and archangel of the power of the Lord and a chief captain among the sons of God? Am not I Israel, the first minister in the sight of God, and I invoked my God by the inextinguishable name?”
St. Justin Martyr shares the belief with the work (
Dialogue with Trypho 125) that the name ‘Israel’ refers to a heavenly being: however, he differs from the
Prayer of Joseph in that he believes that there were not one and the same being but two distinct persons who only happened to share the same name:
[3] Accordingly the name
Israel signifies this, ‘
A man who overcomes power’; for
Isra is ‘
a man overcoming’ (ἄνθρωπος νικῶν), and
El is ‘
power’ (δύναμις). And that Christ would act so when He became man was foretold by the mystery of Jacob’s wrestling with Him who appeared to him, in that He ministered to the will of the Father, yet nevertheless is God, in that He is “
the firstborn of all creatures.”
[4] For when He became man, as I previously remarked, the devil came to Him—i.e., that power which is called the serpent and Satan—tempting Him, and striving to effect His downfall by asking Him to worship him. But He destroyed and overthrew the devil, having proved him to be wicked, in that he asked to be worshipped as God, contrary to the Scripture; who is an apostate from the will of God. For He answers him,
"It is written: 'You shall worship the Lord your God, and Him only shall you serve.’" (Matthew 4:10) Then, overcome and convicted, the devil departed at that time.
[5] But since our Christ was to be numbed, i.e., by pain and experience of suffering, He made a previous intimation of this by touching Jacob’s thigh, and causing it to shrink.
But Israel was His name from of old/from above (ὄνομα αὐτῷ ἄνωθεν), to which He altered the name of the blessed Jacob when He blessed him with His own name, proclaiming thereby that all who through Him have fled for refuge to the Father, constitute the blessed Israel. But you, having understood none of this, and not being prepared to understand, since you are the children of Jacob after the fleshly seed, expect that you shall be assuredly saved. But that you deceive yourselves in such matters, I have proved by many words.
