Walking on Water collects 12 brief meditations by Madeleine L'Engle on the nature of art and its relation to faith. L'Engle, the beloved author of A Wrinkle In Time among others, has written and spoken widely and wisely about the connection between religion and art. The gist of her understanding is as follows: "To try to talk about art and about Christianity is for me one and the same thing, and it means attempting to share the meaning of my life, what gives it, for me, its tragedy and its glory. It is what makes me respond to the death of an apple tree, the birth of a puppy, northern lights shaking the sky, by writing stories." She believes that "[b]asically there can be no categories such as 'religious' art and 'secular' art because all true art is incarnational, and therefore 'religious.'" And "incarnation," in L'Engle's view, means "God's revelation of himself through particularity." In this book there is some slippage between L'Engle's autobiographical and critical voices. As a result, she often claims Christian significance for works whose meaning is not intentionally Christian. She admits this freely: "[B]ecause I am a struggling Christian, it's inevitable that I superimpose my awareness of all that happened in the life of Jesus upon what I'm reading, upon Buber, upon Plato, upon the Book of Daniel. But I'm not sure that's a bad thing. To be truly Christian means to see Christ everywhere, to know him as all in all." ~ Michael Joseph Gross
