Feeling that he is in full possession of Dimmesdale's secret, Chillingworth begins his unrelenting torture of the minister, subtly tormenting him with comments designed to trigger fear and agony. Dimmesdale does not realize Chillingworth's motives, but he nonetheless comes to fear and abhor him.
As Dimmesdale's suffering becomes more painful and his body grows weaker, his popularity among the congregation grows stronger. Such mistaken adoration, however, further tortures Dimmesdale and brings him often to the point of making a public confession that he is Pearl's father. The minister’s sermons are eloquent, but his vague assertions of his own sinful nature are taken by his parishioners as further evidence of his holiness.
Because Dimmesdale is incapable of confessing that he was Hester's lover and that he is Pearl's father — the one act necessary to his salvation — he substitutes self-punishment. He beats himself with a bloody whip and keeps frequent all-night vigils during which his mind is plagued by frightening visions. On one such night while he is seeking peace, Dimmesdale dresses carefully in his clerical clothes and leaves the house.
