A good deal of Middle English prose is religious. The Ancren Riwle teaches proper rules of life for anchoresses (religious women) - how they ought to dress, what work they may do, when they ought not to speak, and so on. It was probably written in the thirteenth century. Another work, The Form of Perfect Living, was written by Richard Rolle with the same sort of aim. His prose style has been highly praised, and his work is important in the history of our prose.
