[3][clarification needed] Wooster was accepted on trial for the Methodist itinerary at the 1793 conference, and assigned to ride the Granville Circuit in Massachusetts.
[8] He travelled north with fellow circuit rider Samuel Coate, reaching the quarterly meeting of the Upper Canada district after a twenty-one-day journey through a lightly populated wilderness.
At the end of the day's public business, Dunham retired with the other conference leaders to discuss organisational matters.
[9] Although Wooster was a preacher of significant faith and fervor, he had a poor constitution, and after circuiting riding in Upper Canada through June 1798,[10] he returned to his parent home ill, suffering from tuberculosis,[11] and died on 6 November 1798.
There he preached numerous sermons around Kingston, often centering on what he maintained were Wooster's last words: "Ye must be sanctified or damned".
[13] Wooster preached in a simple, straightforward style, employing common language which allowed him to appeal widely to people unfamiliar with theology.
At one Methodist meeting around the Bay of Quinte, an audience member was arranged to be disruptive, talking and swearing during the sermon.
