Maybe, although most critical scholars don’t think Paul wrote Colossians.
In terms of Paul’s view of Jesus’s prehuman existence, by far the best indication is Phil 2.5-11, while 1 Cor 8.4-6, 2 Cor 8.9, and a few other passages offer some insight.
In Philippians 2, if we accept that Paul is here referring to Jesus’s prehuman existence, as most scholars do, I think the JW reading of the passage makes the best sense by far. In this passage, Jesus is clearly a heavenly being who is distinct from and subject to God. Instead of trying to usurp God’s position, with an implied contrast with either Adam or Satan, or both, he chose to come to earth as a human, and then he humbled himself even to the point of death. For that reason, God rewarded him and exalted him to a higher position than he originally had and, reflecting Jesus’s humility, this is all still to the glory of God, not himself. This passage so clearly shows that Jesus is a spirit being who is subordinate to God that trinitarians tie themselves in all sorts of knots trying to get it to say something else. It doesn’t flat out say that Jesus is an angel, but what is the name for a heavenly being that is subject to God and does his will? It seems pretty clear. One of the best treatments of the passage I’ve come across is this article by Jack Sanders. I can send a pdf if anyone wants to access it, it let me know.
