In the tale of Sir Gawain and the Green Knight, the lady of the castle tempts Sir Gawain with a magical, green girdle and explains to him that the wearer of this corset "could not be killed by any craft on earth.(1854)" Sir Gawain, amidst an ethical dilemma, accepts the gift and chooses to conceal it from Lord Bercilak. This passage contains three of the main themes of the story, the inner and outer conflicts between Sir Gawain's ethics and desire to live, and the test of religion.
When Sir Gawain is offered the girdle, his knightly principles are questioned. The honorable thing would be to reject the offer or bring it to the lord of the castle, but Gawain places the preservation of his life ahead of chivalry. The knight has withstood the lady's constant barrage of sexual advances, and kept his promise to the lord of the castle, but when the chance to save his life is presented, he accepts the offer with little resistance. He is then ecstatic about the thought that he will survive his meeting with the knight the next day, shown by "He thanked her with fervent heart, as often as he ever might. (1866-7)" Later, Sir Gawain finds three faults in his actions, the first being his cowardice, in direct contrast to the main principles of knighthood, the second being his covetousness, his lust for life, and the third being his lack of faith in God. Even when it is shown that God has forgiven him by healing the wound on his neck, Sir Gawain still feels that he has sinned, and is not as willing to forgive himself. He decides that more atonement is in order, so he makes the decision to wear the girdle from then on, as a sign of his mortal sin, but even then he does not feel that he has been cleansed of his sin. He understands that he will be forced to bear the shame and disgrace of the sin for the rest of his life.
The observers" opinions of whether Sir Gawain is forgiven are the complete opposite of Sir Gawain's.
