E.M. Forster

This line appears in the novel A Room With a View by E.M. Forster: "Paganism is infectious--more infectious than diptheria or piety."

In The Celestial Omnibus and Other Stories, also by E.M. Forster, there is a story called "The Curate's Friend". In this story, the main character has the unique ability to see fauns, a quality none of the other characters share. The man is living an inauthentic life, in several ways out of touch with his truer self. Yet he is committed to this way of existence and the people and things assembled around it. He goes on a kind of picnic with a woman he loves. During the picnic, he encounters a faun. The faun wants only one thing--to serve the man. The man resists the faun's overtures, being attached to his staid but false life. The woman, seeing only half of the interaction with the faun--the man's side--assumes it's the man's embarrassing attempt at comedy. The woman breaks up with the man, and the man gives in to the faun's desire to serve him. The man's life changes; he becomes authentic and happy, that day and forever after, though he must keep the reason a secret, given where he works. 

The story is a kind of Chronicles of Narnia for Religio Romana:

Already in the wood I was troubled by a multitude of voices--the voices of the hill beneath me, of the trees over my head, of the very insects in the bark of the tree. I could even hear the stream licking little pieces out of meadows, and the meadows dreamily protesting.
