"The Second Nun's Tale" juxtaposes the good judgment of Valerian and Tiburtius in immediately accepting Christianity's truths with the very bad judgment of Almachius, who judges Christians as guilty of a crime. In portraying Almachius as a senseless judge, Cecilia points to the fact that only God is the true judge. Accordingly, this story shows those who follow God's rules receiving their just rewards in eternal life with him.
