Aberdeen was one of the congregations with a meeting house of the Rosenorter Gemeinde in Saskatchewan. The founder of this Gemeinde was Peter Regier (1851-1925). He had been appointed Ältester in 1887 in Prussia. He emigrated to Tiefengrund, Saskatchewan in 1893. Enough families had settled in the area so that in 1894 the Rosenorter Gemeinde of Saskatchewan had been founded. In 1909 there were enough families in the wider area to form districts with a minister in charge of each. One of these was Aberdeen which had families worshipping together since 1907 under the leadership of Cornelius Ens. There were 130 members worshipping in this district. In 1910 the meeting house at Aberdeen was completed. During the next decade or so the congregation was served by various non-resident ministers of the Gemeinde. Jacob Nickel emigrated to Aberdeen in 1924 and remained their leader until 1937. During this time he also taught in the Bible School in Rosthern. The meeting house was moved onto a basement at the same site in 1939. The building was renovated in 1950 and again in 1964. In 1962 the Rosenorter Gemeinde was dissolved and each congregation became independent. The membership was 103 in 1963. That figure remained fairly constant; in 2000 it was 102. Leaders of the congregation were: Cornelius Ens (1907-1915), Jacob Nickel (1924-1937), Peter Koop (1932-1946), Heinrich Neudorf (1932-1947), Bernhard Fast (1947-1955), Franz Koop (1951-1973), John Peters (1973-1976, 1983), John Kroeger (1977-1982), Verner Friesen (1984-1991), Rod Suderman (1992-1999), David Neufeld (2000- ).
