I have the suspicion that Pope Francis is a fan of Scrooge, the crusty, mean, emotionally gnarled miser of Charles Dickens' A Christmas Carol.
Dickens called him "a squeezing, wrenching, grasping, scraping, clutching, covetous old sinner! Hard and sharp as flint, from which no steel had ever struck out generous fire; secret, and self-contained, and solitary as an oyster."
