“Psalm 103 and 148 both command Angels to worship God”
Oh yes, of course. I don’t see from there why we should be praying to angels or worshiping them. I don’t doubt they are worshiping God quite constantly in heaven.
But the Psalms *are* prayers. And prayers are merely petitions - that is the reason you have “prayers for relief” when you file a suit in court, or if you asked “what, pray tell, are you talking about?” There is a distinction between such prayer and worship, which is only for God.
