Her beauty is transcendent of her representation of Christian truth. The lion follows Una into the house of mother and daughter who represent the monasteries and their ignorance of the needs of the world. The lion defeats the church robber who brings his steals to the house of the mother and daughter and Una departs in the morning. Faith is the foundation of virtue and it is this virtue that saves Una from Sansloy, a man without the law of God, (Kathryn Walls, "'Add Faint Vnto Our Force': The Meaning of Una's Advice," 530-532). Sansloy defeats the lion because when one is without the law of God then he can defeat the laws of nature. Sansloy takes Una as a prisoner and wishes to have his lustful way with her. When Una cries for help as Sansloy wishes to taint her virtue, the woodgods from the forest emerge and come to the aid of the maiden. Spenser depicts this faunes and satyrs as primitive, idolatrous beliefs of the ancients. They scare off Sansloy and when they come face to face with Una they bow down to her, thinking she is a goddess, not realizing the Christian truth that she represents, (Richard Jordan, "Una Among the Satyrs," 123-132). .
Una's main goal within the poem is to help Redcross achieve true holiness. She represents the truth that Redcross must find in order to defeat the evils of this world. Early on in the poem Redcross is betrayed by the villains Archimago and Duessa and led astray. Convinced that Una tarnished her virtue by images made by Archimago, Redcross departs from the inn they were staying at and in a series of unfortunate events, becomes captured by a giant. Upon waking and learning Redcross left without her, Una becomes distraught but sets out to search for Redcross. Deceived by Archimago as well, Una must look within herself for the truth, and only lets men save her when she can no longer help herself. When Una meets King Arthur and they proceed with breaking Redcross out of the prison of the giant, they defeat Duessa as well.
