 In 1932 he and his brother Harald jointly published "Über drei Haupttypen der religiösen Erlebnisformen und ihre psychologische Grundlage" (On Three Major Types of the Form of the Religious Experience and their Psychological Bases).He published multiple articles, including a series on the historical origins of Christianity, later published in book form as "Hvem Jesus var og hvad kirken har gjørt ham til" (Who Jesus was and what the Church made of him) which criticised liberal theology for indecisiveness and aroused serious disagreements in the theology department of the university.In 1928, Schjelderup applied for a position as vicar in the parish of Værøy and Røst, but although he was the only applicant, the Minister of Church Affairs, Sigvald Mathias Hasund, did not appoint him.
