No need to go too far into the weeds. I'm slow and have already lost sight of the main point.
Main point: is there some SDA doctrine that depends on Jesus being Michael? If so, what is it?
The only verses that probably need to be looked at are ones that concern Michael, Jesus's identity and angels.
For me, it is a fairly simple matter to see Jesus is not Michael. Just sticking in Daniel, one sees various Princes mentioned, like of Persia and Greece, and Michael is grouped among them in Daniel 10:13. Throw in the Enoch reference, and Jesus not being Michael is reasonable.
In my opinion, the only reason to insist Jesus is Michael is because it is somehow important to a denomination's identity.
AV Col 1:27 To whom God would make known what [is] the riches of the glory of this mystery among the Gentiles;
which is Christ in you, the hope of glory:
"
Main point: is there some SDA doctrine that depends on Jesus being Michael? If so, what is it?",
It's a test from GOD for all who will be lost. Recognizing Jesus everywhere in the bible, so that those who are Jesus', can be like Jesus.
A Little review in critical thinking ...
AV Mt 25:40-41 And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done [it] unto one of the least of these my brethren, ye have done [it] unto me. 41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
A subtle understanding from these verses is, NOT RECOGNIZING Jesus in the Bible or other believers is hazardous to eternal life.
Rereading this quote from before,
What is Jesus' major reason of the goats, failing to get eternal life ???
More evidence about "
goats" ...
AV Re 16:4-7 And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood. 5 And I heard the angel of the waters say,
Thou art righteous, O Lord, which art, and wast, and shalt be, because thou hast judged thus. 6 For they have shed the blood of saints and prophets, and thou hast given them blood to drink; for they are worthy. 7 And I heard another out of the altar say,
Even so, Lord God Almighty, true and righteous [are] thy judgments.
"
For they have shed the blood of saints and prophets, ...", GOD's people in the time of the end, will be murdered in mass.
"
Even so, Lord God Almighty, true and righteous [are] thy judgments.", And GOD will past "
thy judgments", denying them eternal life.
Heart of the matter for GOD ...
AV Hb 10:29-30
Of how much sorer punishment, suppose ye, shall he be thought worthy,
who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace? 30 For we know him that hath said,
Vengeance [belongeth] unto me, I will recompense, saith the Lord. And again,
The Lord shall judge his people.
"
who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, ...", This is symbolic language, and needs to be understood as such.
So what does this mean to you as GOD's "
sanctified" in symbolic meaning ???
Your other option is to give a literal meaning, if so what is it ???
The results according to GOD ...
"
Vengeance [belongeth] unto me, I will recompense, saith the Lord. And again,
The Lord shall judge his people.", This should be clear that "
The Lord shall judge his people." and "
Vengeance [belongeth] unto me" will be the results of GOD's "
thy judgments".
Revelation and Hebrews was clear that those who are GOD's "
sanctified" that can not recognize Jesus and/or "
the blood of the covenant" will lose eternal life.
Summary Conclusion ...
AV Jn 5:25
Verily, verily, I say unto you, The hour is coming, and now is, when the dead shall hear the{definite article} voice of the Son of God: and they that hear shall live.
AV 1Th 4:16 For the Lord himself shall descend from heaven with a shout, with
the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
AV Ju 1:9 Yet
Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said,
The Lord rebuke thee.
"
The Lord rebuke thee.", Will receive GOD's "
thy judgments", up to and including "the devil he disputed". So dispute GOD's resurrection power, and those that do, join 'the devil's "
thy judgments".
It's really your choice to decide if Jesus in all forms, has resurrection power over you, and others. And accept GOD's "
thy judgments" on those it falls upon who do not.
Bonus feature ...
"
who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing", Who have "
trodden" the sabbath that Jesus kept in righteousness "
under foot" ???
AV Jn 16:2
They shall put you out of the synagogues: yea, the time cometh, that whosoever killeth you will think that he doeth God service.
When did GOD asked anyone "
sanctified" in the NT/NC to "
killeth" anyone ???
“Question - Which is the Sabbath day?
“Answer - Saturday is the Sabbath day.
“Question - Why do we observe Sunday instead of Saturday?
“Answer - We observe Sunday instead of Saturday because the Catholic Church, in the Council of Laodicea (A.D. 364), transferred the solemnity from Saturday to Sunday.”
Peter Geiermann, C.S.S.R., The Convert’s Catechism of Catholic Doctrine, p. 50, 3rd edition, 1957.
Check Question: Who and when made sabbath "
an unholy thing" ???
Check Question: Who and when made sunday holy ???
AV Re 19:20
And the beast was taken, and
with him the false prophet that wrought miracles before him, with
which he deceived them that had received the mark of the beast, and
them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
Those suffering GOD's "
thy judgments", a very salvific issue in GOD's works.
Yours in Christ, Michael
