Lines 77-87. What is the minister's usual style or preaching? Is he using the same style now?

Hooper's style was usually mild and persusive.

"Mr. Hooper had the reputation of a good preacher, but not an energetic one: he strove to win his people heavenward by mild, persuasive influences, rather than to drive them thither by the thunders of the Word."

No, his style has become gloomy and dark.

"The sermon which he now delivered was marked by the same characteristics of style and manner as the general series of his pulpit oratory. But there was something, either in the sentiment of the discourse itself, or in the imagination of the auditors, which made it greatly the most powerful effort that they had ever heard from their pastor's lips. It was tinged, rather more darkly than usual, with the gentle gloom of Mr. Hooper's temperament."
