Arnfeld was the son of Christian Morck and Christine Christensen. He married twice, to Irene Norre (1944) and Hildur Thorkildson (1948).
A graduate of Augustana University College in Camrose, he became a Lutheran minister and worked as a missionary in South America. As of 1966, he was in Bogota, Colombia.
He served on the editorial staff of the Lutheran Synod of Colombia which translated the hymnal into Spanish: They took 8–9 years to translate the lyrics, and two more to prepare the music.
