Rebecca:
In Philo's view, would God direct all of His angels to worship these 'gods' / Logos? (re: Hebrews 1:6)

Medini:
What is the Greek word used there? Does it always have to mean worship? I think you will find that it is just as credibly rendered as "bow down". Considering that our midrashic sources have G-d directing his angels to bow down to Adam, it wouldn't surprise me to have them bow to this supreme angel/"god"/Logos as Philo presents it.
