What do Dimmesdale's parshioners infer from his sermon?

The think the Holy Spirit had entered their minister and possessed him. They thought him to be prophet like,

"nor had inspiration ever breathed through mortal lips more evidently than it did through his. Its influence could be seen, as it were, descending upon him, and possessing him, and continually lifting him out of the written discourse that lay before him, and filling him with ideas that must have been as marvellous to himself as to his audience."
