Aulén wrote a huge amount of material in his lifetime and his most famous work –Christus Victor – was published in Swedish in 1930, with an English translation in 1931.

Aulén was also an avid composer and was heavily involved in the committee responsible for the Swedish Church's new hymn book published in 1937.

Aulén retired his bishopric in 1952, returning to Lund to devote himself to his academic work, surviving his wife who died in 1959.

Aulén was a prominent member of the 'Lundensian' school of theology, along with Anders Nygren, Ragnar Bring and Gustaf Wingren.

[9] Regardless of whether they agree with his arguments, most contemporary discussions of the Atonement follow Aulén's three categories,[1][2] and the term Christus Victor has become synonymous with the 'classic' view he advocated.
