Sack was born in Goldap, East Prussia (today Gołdap, Poland) and studied Lutheran theology at the University of Königsberg. He started to work as a Pastor at the Parish of St. Anschar and the „Bethlehem”-hospital in Eppendorf, Hamburg. In 1914 he returned to East Prussia and became a Pastor with the Evangelical State Church of Prussia's older Provinces in Lyck (Ełk). In 1924 he moved to Pillkallen (Dobrovolsk) and in 1927 to Lasdehnen (Krasnoznamensk). After the Nazis took over power in Germany he opposed the Nazi-influenced "German Christians" and joined the Confessing Church. In 1942 he was arrested by the Gestapo, accused of "Weakening the Resistibility of the German people" after Sack had expressed his concerns about the German victory in a confirmees lesson.
