What idea does the description of the prioress in the prologue to Chaucer's The Canterbury Tales convey?

Having now introduced the Knight (the highest ranking pilgrim socially), the narrator now moves on to the clergy, beginning with The Prioress, called 'Madame Eglantine' (or, in modern parlance, Mrs. Sweetbriar). She could sweetly sing religious services, speaks fluent French and has excellent table manners. She is so charitable and piteous, that she would weep if she saw a mouse caught in a trap, and she has two small dogs with her. She wears a brooch with the inscription 'Amor vincit omnia' ('Love conquers all'). The Prioress brings with her her 'chapeleyne' (secretary), the Second Nun.
