Sørenssen received his cand.theol. in 1785. He worked as a teacher in his home town of Christiansand and in Strømsø in Drammen, before in 1797 he became a priest in Risør. In 1804, he was the most important priest in Christiansand. On 11 April 1811, he was invited to be bishop of Christiansand, and Sørenssen was the last Norwegian bishop to be ordained in Copenhagen. The bishopric covered Agder and Rogaland at that time.
He was a representative at the first two Stortings, and was also a politician from 1814 to 1817. He did not have a special interest in politics, and did not speak at the Storting's meetings.
He died on 16 August 1845, on the way between Moss and Son on a visit.
