Flannery O 'Connor put much conscious thought into her dual role of Catholic and fiction writer, and reading her written reflections on the matter reveals that she had developed a whole literary philosophy devoted to reconciling the two, and joining them into a single unified force to prove the truth of the Faith. O 'Connor observed a Manichaeism in the mind of the average Catholic reader, resulting from a conceptual separation between nature and grace in considerations of the supernatural, thus rendering fictional experience of nature as either sentimental or obscene. Nature imagery is everywhere in O 'Connor, and it is often used to reinforce the negativity of the lives and mental states of her characters.
The novice reader of O 'Connor may well wonder how her work, grotesque and violent as it is, would be considered "Christian" or "Catholic" significance. As to the, at times, extreme use of violence in her significance, O 'Connor 's literary philosophy allowed for the use of it in the service of some greater vision of spiritual reality. Heidegger was a definite influence on O 'Connor, and ideas such as this, as well as his concept that essential truth is a mystery that pervades the whole of human existence, dovetail perfectly with the larger theological interpretation
