Hebrews Part 2

INTRO: In the first message I introduced the letter to the Hebrews. Now I want to first introduce the first 2 chapters. Angels are the concern of the first two chapters. Angels are mentioned 12 times in this book, and 10 of those are in chapters 1-2. So the theme of angels dominates these two chapters. I have already hinted at why the writer deals with angels in these two chapters. A writer I quoted in the previous message said this:
"The contrast between Christ and the angels in Heb 1–2 has aroused the curiosity of many interpreters. 1 Were angels merely chosen as one among other OT mediators (e.g. Moses, Melchizedek, Levitical priesthood) to show the superiority of Christ as the ideal high priest? Or were there distorted teachings on angels among first-century readers that demanded correction? Some suggest the author's purpose was to refute an angel Christology, 2 while others see angelic veneration similar to that practised in Colossae (Col 2.18) in view. 3 Yet the book contains neither a prohibition against the 'worship of angels'" https://www.marquette.edu/maqom/GleasonAngels.pdf
What he is saying is, why do the first 2 chapters of Hebrews deal so much with angels? Is it that the writer merely mentions angels to show the superiority of Jesus Christ as the ideal High Priest? Were there false teachings that had crept in among them about angels? Or was there an unhealthy veneration of angels such as is mentioned in Colossians 2:18? This verse says:
