Dorothy Sayers on Writing and the Trinity

My eighth grade English teacher introduced me to Shakespeare, E.E. Cummings, and essays by writers on writing. I still read them all. Currently I am enjoying a piece of non-fiction - a theological analogy by the murder mystery writer, Dorothy L. Sayers, on how the structure of a creative (author's) mind is a reflection of the Christian Trinity. She discusses the book as at one and the same time an Idea, an Energy, and a Power. The "Book as Thought" is analogous to God the Father; the "Book as Written" compares to God the Son, and the "Book as Read" is for God the Holy Spirit. Throughout the piece she uses her own experience as the author of the Peter Whimsy books to illustrate her claims. They make sense to me as an author as well. I think that this book should be the basis for the meditations of a Christian writers' retreat. I think I will try to make that happen.
