Rosendal was born in Grevie, Skåne, the son of Andreas and Teolinda Rosendal. His mother died early and his father moved to the United States so he and his sister were raised by an aunt.
After graduating from Lunds Privata Elementarskola he began his theological studies at Lund University in 1918. He was ordained on 25 May 1922 by bishop Gottfrid Billing and moved to Väsby to begin his work as a priest. By the recommendation of Bo Giertz he started to read books of Carl Olof Rosenius, which made a lasting impression.
Rosendal himself used the neo-thomistic paradigm and resisted all kinds of liberal theology as well as the dialectical theology of Karl Barth.
Rosendal was one of the theologians that worked for the foundation of the International League for Apostolic Faith and Order (ILAFO). In Sweden his influence can be seen in the foundation of the high church organization arbetsgemenskapen Kyrklig Förnyelse (aKF), which was inspired by his book, Kyrklig förnyelse.
