Wrycza served a number of parishes between his ordination and the beginning of the First World War, and remained a fully committed Roman Catholic priest until his death. He also spent his life as an activist, however, for the Kashubian and later the Polish causes. In 1909 he was one of the founding members of the Society of Young Kashubians along with Aleksander Majkowski, Jan Karnowski, and Leon Heyke. Drafted into the German Army in 1914, he served for two years as a medic before returning in 1916 to his priestly duties. In 1917 he founded the Society of Polish Youth, an organization devoted to taking control of Poland by armed struggle, and barely escaped execution by the German "Grenzschutz Ost" in 1919 as a member of the Military Organization "Pomerania."Ks. ppłk JÓZEF WRYCZA at sitwp.umwp.pl
