What is the author's style in Orpheus Descending by Tennessee Williams?

There are various hints of a religious dimension to the play in the many allusions to Christianity. Val's full name, Valentine Xavier, contains the names of two Christian saints, hinting perhaps at another element of his nature. It might seem that the sensual Val is an unusual candidate for sainthood, but he does boast of his capacity to overcome the demands of the physical body—a self-denying asceticism characteristic of some forms of saintly life. For example, he tells Lady that he can sleep on a concrete floor or go without sleep for forty-eight hours if he wishes.
