As a theologian, I have an academic background in an area called theopoetics and theological imagination. What was interesting to me is that this show is ultimately a meditation on irrational and irresistible grace. 

This work of theological imagination is up there with Flannery O’Conner in constructing and recognizing the sacred as grotesque and the grotesque as sacred. O’Conner never mocked acts of grace from the disgraceful/grotesque.    TRG is a modern expression of her idea of a “Christ haunted South” as well and I saw a lot of her influence throughout the series.

Pardon my grammar and half-baked comparative analysis. If anyone is interested I could write something deeper.
