More than most other virgin martyrs, Cecilia really knows her stuff, where "stuff" is Christian Theology. Cecilia uses this knowledge to convert pagans by preaching and teaching. So important is this "loore" that even after Cecilia's head is dangling from her neck, she continues to teach and preach to the faithful. Cecilia accuses Almachius of a lack of education because of the argumentative errors he makes; for her, this "lewedness," or unlearnedness in rhetorical matters, is a sign of a similar unlearnedness in his soul, one that could likely be rectified with her "wise loore." Yet despite the importance of knowledge and teaching in "The Second Nun's Tale," certain passages imply that it is not enough for a full Christian faith: after an gaining knowledge of Christianity, a convert must receive the sacraments and commit to living a life free of sin, in this way perfecting one's learning.
"The Second Nun's Tale" focuses more on the power of wisdom and knowledge than on its actual content.
In "The Second Nun's Tale," a character's apparent knowledge and learnedness are an indication of the state of his soul.
