Hebrews 1:5
Hebrews 1:55For to which of the angels did God ever say: “You are My Son; today I have become Your Father”? Or again: “I will be His Father, and He will be My Son”?
"Today I have become your father" (NWT) is read as proof that Jesus had a beginning — "today" is a point in time, therefore Jesus was begotten at some point. Combined with "firstborn of all creation" ( NWT) and , the Watchtower builds the doctrine that Jesus is the first and highest created being — Michael the Archangel before incarnation.
is the knockout text against the Jesus-is-Michael doctrine. The author poses a rhetorical question — "to which of the angels did God ever say, 'You are my son'?" — and the expected answer is "none." If Jesus is Michael, the argument collapses: an archangel son would be the obvious counter-example. The "today" of (which quotes) is enthronement language — the day of Messianic royal installation, applied in the New Testament to the resurrection and ascension (; ). Not a statement about ontological origin; a statement about installed kingship. The Son is eternal; his installation as messianic king happens in time. Doorstep form: "If Jesus is Michael, name any other angel in Hebrews 1 who could have been the counter-example to 1:5. The author says there is none."
