“These parallel passages are speaking of the same event. Paul, in Thessalonians, calls it “the voice of the Archangel” and John, in His gospel, calls it “the voice of the Son of God.”
Michael the Archangel is another title/name/character of Jesus Christ.

Because while I appreciate the sentiment, I don’t think it’ll happen.
