How do the various saints mentioned in Fifth Business contribute to our understanding of Dunstan Ramsay's character?

After Mrs. Dempster brings William back to life, Ramsay begins to believe she has more than just an ordinary preacher’s wife in her. She then appears on the statue of the Madonna, and later Ramsay finds out that Surgeoner attributes his salvation from vagrancy to her gift of herself in the pit.

These spiritual events are not explained scientifically, and the reader gets the feeling that Ramsay savors the mystery of the apparition of a miracle. They seem to be a confirmation that even if there is not a well-defined divinity overseeing things, there is at least a human function creating the spiritual experience of saints bestowing favors on the living.
