What are the characteristics of the Prioress that indicate that she may not be a devout member of the Church? Which of the seven deadly sins might she represent?

The Prioress is supposed to be a religious figure but she does not look or act the part. Instead of rosary beads with a crucifix, she carried vanity beads. She dresses garishly rather than simply. She is also extremely large which tells us she suffers from the sin of gluttony.
