Johan was the son of Svend Busch Brun, a farmer, and Mette Catharina Nordala.
He was educated in Trondjhem (now Trondheim), and was appointed family tutor to Councilor Meinche, accompanying his son to Soro, Denmark.
He returned to Trondjhem shortly thereafter, where he failed his theological and homiletic exams, and spent three years there teaching and preaching.
He traveled to Copenhagen in 1767, and after intense study passed his theology exams.
In 1771, he became private secretary to Bishop Gunnerius, and was ordained the next year.
He became pastor at the Korskirken (Church of the Cross) in Bergen, Norway, in 1774, and Bishop of Bergen in 1804.
