Viva Cristo Rey!
Anyone who thinks man is king of the universe is practicing and preaching something other than orthodox Catholicism. Yes, man is the pinnacle of God’s creation but man is not and never will be “king” of the universe.
My guess is he meant “pinnacle of creation” or something to that effect and misspoke. I want to believe he was just sloppy and it doesn’t mean a profound misunderstanding on his part. He is the pope after all.
Based on the truncated quote by the poster and taken alone, it reads to me that the center-of- reflection and the center-of-life IS the King of the universe (whom we know as our trinitarian God). No?
