I love “Lucifer” but their theology is difficult to fathom. I think they are building it as they go to survive the plot (just like “Charmed” did).
It is a lot of fun, hilarious, very human, has great music deftly supporting the storyline, and wildly Progressively Leftist.
What it has in common with Pope Frank is it's entertainment.
But "Lucifer" is better.
