Matthew Poole's Commentary: "And whether he will put forth an audible voice or not at that day, or whether this archangel be not the same with Christ himself, who is the Head of all principality and power,
Colossians 2:10, I leave it as doubtful..."
Meyer's NT Commentary: "...Ambrosiaster and Olshausen, as well as Alphen and Honert (in Wolf), understand no angel at all, but the two first understand Christ (!), and the two last the Holy Ghost (!)..."
Gill's Exposition of the Entire Bible: "the sense be, that Christ shall descend from heaven with a voice, or shall then utter such a voice, as will show him to be the archangel; or as the Syriac version renders it, "the head", or "prince of angels"..."
Obviously you will be able to cherry pick a few people that will back your view. I do not doubt that. But your first quote undercuts your view. Matthew Poole states that he doubts that this archangel is Christ himself.
Are you saying that Jesus and Micheal are the same?
I think that this may be a Jehovah Witness teaching.
Anyone who thinks he is infallible in his understanding of the verse is only deceiving himself.
Lucky we have the Holy Spirit to guide us with these things. He will lead us into all truth. So, in time, those who have the Holy Spirit who are interpreting incorrectly, will eventually understand.
How many of us are actually living like we believe it, though?
Yes, this is the real issue, bigger than all the end-times debates. Many people who call themselves believers will debate end times until their face is blue but are their lives reflecting what they profess to believe?
If we truly believe in God, judgment, heaven and hell, and that Christ died for sin, then our lives should reflect that. As James says, faith without works is dead, a profession without a changed life is empty.
And part of living in a way that shows true belief is to do as God commanded, to tell as many people as possible the Gospel. Also, part of that change is to love our neighbour enough not to stay silent. If we really believe people face judgment, then warning them and pointing them to Christ is an act of love, not harshness. To not warn them, as many believers choose not to do, is not loving our neighbour.
Penn Jillette once said, "If you know of everlasting life, and you know of everlasting death, how much do you have to hate somebody to not tell them of it?"
Acts 1:8 shows that the Spirit was given so that we would speak. So, a Spirit-shaped life will move toward telling people what Jesus did on the cross, even if imperfectly, even if with some fear.
The question isn’t just what do we believe about the end, it’s, are we living and speaking like it’s true?
So, live in a way that honours God and don't be like most Christians who stay quiet. Love people enough to tell people the Gospel.
