What is the theme in The Scarlet Letter by Nathaniel Hawthorne?

The Scarlet Letter deals with the theme of sin and guilt. Hawthorne, however is not content to simply categorize these traits. Although Hester and Dimmesdale are the principal "sinners" their love provides a sense of absolution that lies beyond the context of the church. Their sin is actually one of the only examples of love in the book. The fact that Hester is eventually able to transcend her indiscretions within the village adds another layer to this theme in the story.
